1918-1960s


In World War I, in the last year of the conflict, the Germans developed the Bergmann MP 18, a small, hand-held automatic weapon with a 'rifle-like' form (including a wooden stock). Even though it looked like a small rifle, it used 9mm pistol ammunition, which introduced the idea of an automatic weapon that fired pistol rounds. Up until this point, machine guns were always heavy weapons mounted on tripods or wheeled artillery mounts. While heavy machine guns such as the Maxim gun and the Vickers gun were fearsome defensive weapons in a built-up emplacement, they were very hard to move to a new position if the army had advanced to a new area, or if it had to fall back. The German Army recognized that to break the stalemate of trench warfare

, a light, hand-held automatic weapon was needed that would enable individual soldiers to move with the gun to new firing positions.

The Germans also did experiments with converting various types of pistols to machine pistols (Reihenfeuerpistolen, literally "row-fire pistols"). The Luger P08 long barrel pistol was issued in World War I to German artillery crews. It was manufactured with a longer barrel as it was recognized that artillery crew needed a lighter weapon than a rifle but with similar accuracy to defend themselves. It had a newly developed pistol cartridge, the 9mm Parabellum, which was designed for low recoil without sacrificing penetration and stopping power. Although not armour piercing, the bullet more than sufficed for the time.

Unlike the Luger, the Mauser C96

 pistol was modified to fire in a fully automatic mode. First produced in 1896 as one of the first commercially successful and practical semi-automatic pistols, Spanish gunmakers in the late 1920s introduced "select fire" copies of the C96 with detachable magazines, and in the early 1930s Mauser engineers introduced the model 711 and 712 Schnellfeuer variants, which included a fire selector mechanism allowing fully automatic fire at a rate of 1000 rounds/minute. Due to the weapon's light barrel, the fully automatic rate of fire could only be used for short bursts.

 mechanism and the double-action trigger. In addition, the Stechkin APS has an automatic fire mode, which is selected using the safety lever. In burst or automatic fire, the pistol should be fitted with the wooden shoulder stock; otherwise, the weapon quickly becomes uncontrollable. The Stechkin was intended as a side arm for artillery soldiers and tank crews. In practice, it earned a strong following in the ranks of political and criminal police, special forces and the such. Many KGB and GRU operatives favored the Stechkin for its power and magazine capacity. Though somewhat heavy and cumbersome, it was the only "high-powered" alternative to the modest-performing PM. As a pistol, the Stechkin is being slowly replaced by the Yarygin PYa; as a PDW, it was replaced by the AKS-74U compact assault rifle, now widely used in law enforcement.

1970s-1980s





Since it is difficult to control machine pistols when they are fired in full automatic mode, in the 1970s, some manufacturers developed an "intermittent-fire" setting that fires a burst of three shots instead of a full-automatic stream. In the 1970s, the Italian Beretta

In 1988, an unusually designed US 9mm machine pistol named the Calico M950 was introduced. Unlike most machine pistols, which use magazines in the pistol grip or in a vertical box, the M950 uses a 50-round or 100-round helical magazine which is mounted parallel to the barrel. To get a sense of how the helical magazine appears, and how it is mounted, one can imagine a machine pistol with a bulky optical scope mounted on the picatinny rail on the top of the weapon.

 and the compact versions of the Uzi series have been placed in both classes. The popularity of submachine guns in recent years has led many weapons previously described as machine pistols to be advertised to as submachine guns, such as the Brugger & Thomet MP9 (formerly known as the Steyr TMP

).

The Steyr TMP (Tactical Machine Pistol) is a 9 mm blowback-operated, rotating-barrel weapon that is 282 mm long and that can fire 800-900 rounds per minute; despite its small size, lack of a stock, and the fact that it is called a "tactical machine pistol", it is often classed as a compact submachine gun. Likewise, the German Heckler & Koch MP5K (a weapon small enough to be concealed on one's person or in a briefcase), is also classed as a compact submachine gun.

A machine pistol is typically based on a semi-automatic pistol design. While most machine pistols are designed to be fired with one hand, their light weight, small size, and extremely rapid rates of fire make them difficult to control. To improve accuracy, some machine pistols are fitted with a shoulder stock

 offers an optional forward handgrip, which is another way of increasing weapon controllability in full automatic mode.

Tactics


There are many tactics where machine pistols come into play, including room clearing, personal defense, close quarter battle and door breaching.

Military


As an offensive weapon, the machine pistol has limited uses, because it fires pistol ammunition and has a short barrel, which means that it is both inaccurate and lacks power in open-country fighting at a several-hundred meter range. When the machine pistol was first introduced during the last year of World War I, it was used in trench warfare

. In World War II, machine pistols were carried by platoon leaders, artillery crews, and tank crews.

In the decades after World War II, machine pistols were used in close quarter combat where a rifle would be too unwieldy, such as in urban house-to-house fighting or in tunnels. While training doctrines for machine pistols vary between armies, in general, soldiers are instructed to use the weapon for short bursts, rather than for an uninterrupted period of automatic fire, because the weapon easily gets out of control in sustained firing, which means that many of the rounds may be off target. As well, given the high rate of fire of machine pistols, sustained firing wastes ammunition.

In the 1990s and 2000s, as body armor became increasingly common on battlefields, the machine pistol became less useful in a military setting, because its low-powered pistol ammunition is not able to penetrate ceramic-plated Kevlar military vests. As a result, armies began to issue a new weapon to artillery crews and tank crews: the personal defense weapon
Personal defense weapon

, a compact submachine gun-like firearm which incorporates some of the advantages of a carbine, in that it can fire armor-piercing, higher-powered ammunition. Unlike the machine pistol, which is a relative of the semi-automatic pistol, the PDW is more like a scaled-down rifle.

One of the advantages of using machine pistols is that they use the same ammunition that is used in standard-issue pistols. This means that a soldier who is equipped with a machine pistol as his primary weapon and a pistol as a backup defense weapon can use the same ammunition This allows a soldier to carry one only type of ammunition. In contrast, PDWs usually use specialized or proprietary ammunition in unusual calibres.

Military machine pistols usually use fully jacketed ammunition in accordance with the Hague convention. Fully jacketed cartridges are less likely to become deformed and flattened on impact, which means that the damage that they do to the body is moderated. This actually leads to worse injuries than unjacketed or hollowpoint rounds would do to stop an attacker. Some special forces use specialty ammunition in machine pistols or PDWs, such as loading several tracer rounds per magazine to aid in night-time shooting.

Law enforcement

s for VIPs security are sometimes issued machine pistols rather than submachine guns for tactical and media considerations. Whereas a team of bodyguards carrying larger submachine guns may indicate to would-be aggressors that the VIP is an important politician, a machine pistol such as the Glock 18 can be concealed in a standard holster. Since even the unholstered weapon is indistinguishable to most observers from a standard pistol, this may lessen attention from media or potential attackers as to the security measures that are in place.

When bodyguards are carrying a machine pistol in a concealed holster, they have to choose a weapon that does not have parts that might snag when the weapon is being withdrawn from the holster. For similar reasons, a bodyguard with a holster-carried, concealed weapon is typically not able to mount accessories onto the weapon, such as optical sights or forward handgrips. The exception is cases in which a bodyguard conceals the weapon in a briefcase.

Law enforcement agencies use machine pistols for hostage rescues and for breaching gang compounds because the weapons offer a very high rate of fire in a small weapon, which can be maneuvered inside houses and stairwells, places where an assault carbine such as the Colt M4

 would be unwieldy. Another reason that law enforcement agencies use machine pistols in hostage rescue situations is that the low-powered pistol ammunition loses its energy, which means that the bullets are less likely to go through walls and injure innocent parties. Some Mexican police officers working in urban environments carry both a 9 mm machine pistol and a standard semi-automatic side arm.

Air marshals who provide security on private airplanes also carry machine pistols may use speciality ammunition such as frangible bullets, which break apart when upon impact. Frangible bullets such as the Glaser Safety Slug are designed to ricochet less and be less likely to puncture the hull of an aircraft, which lessens the danger of decompression if the officer has to fire on an attacker.

When law enforcement agencies are using machine pistols in non-concealed settings, this makes it feasible to add accessories such as optical sights, laser sights, flashlights, forward handgrips, rear stocks, or sound suppressors. Many 2000s-era machine pistols have mounting rails to facilitate the addition of accessories. Agencies sometimes use sound suppressors for maneuvers in which it is anticipated that shots may be fired indoors, because the sound pressure from indoor firing can be deafening. Some machine pistols offer the option of using translucent plastic magazines which allows the officer to quickly verify the level of ammunition left in the magazine. Another option that law enforcement officers may use on occasion is high-capacity magazines such as single or double drum magazines.

Different law enforcement agencies in different countries have different regulations regarding how machine pistols are loaded and carried. Depending on the type of machine pistol, some agencies train their officers to carry the weapon with a round in the chamber, the weapon cocked and the safety on. Other agencies may prefer that officers carry the weapon without a round in the chamber. While this makes the weapon safer to carry and reduces the likelihood of an accidental discharge, it also means that there will be a longer delay before the officer can fire the weapon.

Agencies also have different training doctrines regarding how the weapon is drawn and brought into position onto the target. Variants include withdrawing the weapon while pointing it downwards, then bringing it up towards the target; the same method but pointing the weapon upwards, and bringing it down towards the target; and the cross-body draw. The first method may be safer, in that if there are any unintended discharges, they will go into the ground. With a machine pistol that can empty its 20-round magazine in a second and a half, bringing the weapon into play by moving it down onto the target or using a cross body draw could result in unintended injuries if the weapon accidentally discharges.

Criminal use



MAC-10 and TEC-9


In the decades after the 1980s, there were newspaper reports about the use of the MAC-10 or the Tec-9 in crimes, including gang-related crimes and the Columbine High School massacre
Columbine High School massacre
The Columbine High School massacre occurred on Tuesday, April 20, 1999, at Columbine High School in Columbine, an unincorporated area of Jefferson County, Colorado, United States, near Denver and Littleton. Two senior students, Eric Harris and Dylan Klebold, embarked on a massacre, killing 12...

. The Tec-9 (known as the AB-10 after 1994) "bears the dubious distinction of being one of the most widely used 'criminal' guns in USA"; it "was used in several mass murder cases...[,] street fights and other violent crimes." The Tec-9 is sold as a semi-automatic weapon, but soon after its release in the US, the "US Bureau of Alcohol, Tobacco and Firearms (BATF) found that this semiautomatic pistol can be easily converted back to full automatic, and restricted it[s] manufacture."

The MAC-10 is "...known on the streets as 'Spray and pray' because of its popularity in drive by shootings and its ability to fire up to 1000 rounds of ammunition every minute" (sic); gun websites claim that the nickname is also a reference to the weapon's inaccuracy. An article on California street gang violence states that "killings and drive-by shootings have evolved as the most frequent violent crimes committed by gang members since the early 1980s..., with an abundance of large-caliber handguns, shotguns, and automatic and semi-automatic weapons--including AK-47s, Mac-10s, and Uzi submachine guns".

In September, 2010, a UK newspaper reported that a member of the gang Peckham Young Gunz was "accused of helping to hide a Mac-10 machinegun used in the execution of Curtis Smith". An article in another UK newspaper described a case in which "Gangsters wielding hand guns and a powerful MAC 10 machine pistol struck three times within hours in Wolverhampton"; in one event, a "group of men brandishing a MAC 10 machine pistol sprayed a nearby pub with a hail of bullets".

A UK newspaper article describes a 2003 case in which two teenage "girls were shot accidentally, detectives think, by gunmen from a gang known as the Burger Bar Boys who were aiming for nearby targets in the Johnson Crew, a rival gang. The gun used in the shooting, a Mac 10, fires so rapidly it is difficult to control. Among gangsters it is known as 'the spray and pray'". Police attribute the deaths "to a feud between rival gangs".

A US newspaper reported that an alleged gang member of Juggalo Rydas, Dewey W. Dixon, "will be serving a mandatory 15-year prison sentence for shooting up an apartment with a Mac-10" in September 2008. The prosecutor stated that "This case...has all the hallmarks of criminal street gang activity: a drive by shooting in response to a perceived slight and a graffiti tagging of the intended victims' apartment." A UK newspaper reported the case of a self-taught gunsmith named Grant Wilkinson, who "was ordered to serve a minimum term of 11 years after a jury found him guilty of running a gun factory supplying lethal Mac-10 weapons to criminals, mainly in London". Wilkinson "...adapted blank-firing replicas [of Mac-10s] into live-firing guns" in his home workshop.

A CBS news article describes a 2009 US case in which police shot and killed a man in Times Square after he opened fire on police officers with a Mac 10. In another US case in 2009, "jurors found Chanreasmey Prum guilty today of first-degree murder,
three counts of attempted murder, and gang and gun charges". Prum was "wearing a mask and carrying a MAC-10
submachine gun, [as] he approached a party barbecuing at the park" and then shots were fired and a 13-year-old boy was killed.

During the 1990s in Croatia, "illicit copies" of "machine pistols were manufactured locally", including the "‘ERO’, an exact copy of the Israeli UZI machine pistol". These illegally made Croatian weapons "also ended up in the Dutch criminal world: between 1998 and 2000, a couple dozen ‘Croatian UZIs’ were seized". In Croatia, "machine pistols of the American Ingram brand" were also illegally copied and manufactured.

Gavrilovic was "a former member of Serbian State Security", who shortly before his death had "... provided documentary evidence of corruption, even naming names."

Criticism


Machine pistols have long been criticized for their inaccuracy. The inaccuracy of most machine pistols occurs because it is hard to control a fully automatic weapon that has such a low weight and in many cases, lacks a proper shoulder stock. As a result, in the hands of all but the most expert shooters, machine pistols being fired on full automatic tend to rise up during firing. As well, machine pistols often have very short barrels, which means that the bullets are not accurate beyond a hundred meters or so. One solution is to design the weapon so that it can fire three-round bursts, rather than uninterrupted automatic fire. Another solution is to steady the weapon in some fashion, either by outfitting it with a shoulder stock, using a shoulder strap to pull down on the front of the barrel, or resting the weapon against a hard surface which can be used as a bracing point.

Gunsite, a US firearms training facility, decided against teaching machine pistol firing when it was founded in 1976. Facility experts believed that it is "a slob's weapon, useful only by half-trained or poorly motivated troops"; they claimed that the machine pistol "hits no harder than a pistol and is no more portable than a rifle." Nevertheless, even the critics from Gunsite concede that the machine pistol is useful for a few situations, such as boarding an enemy boat in low light or when repelling boarders in a naval situation. Walt Rauch notes that "...despite the 50 to 70 years of bad press that has accrued to the concept of shooting a hand-held machine pistol", in which critics contend that the weapon will "spray bullets indiscriminately all over the area", he believes that the 2000s-era models such as the Glock 18 are controllable and accurate in full-auto shooting.

Fictional usage

, the title character uses a Beretta 93R with a futuristic dress and retitled the "Auto-9". A review of the film noted that even though it was a futuristic film, the film's design esthetic depicted machine pistols in a manner that was "...firmly grounded in design trends that were already at work in the 1980’s": the futuristic-looking and "...daunting machine pistol [used by the RoboCop] was just a slight redress of a real-world firearm, the Beretta Auto-9."
