The [[MAC-10]] and [[MAC-11]] were 1970s blowback-designed weapons with the magazine carried in the pistol grip and a select-fire switch. The [[.45 ACP]] MAC-10 had a rate of fire of 1,100 RPM, and the 9×19mm version 1,200-1,500 RPM. The MAC-11 could also fire 1,200-1,500 RPM with its lighter [[.380 ACP]] cartridges. These guns were designed by [[Gordon Ingram]] and [[Military Armament Corporation]] in the US. The weapons were used in special operations and covert applications in Vietnam and by Brazilian anti-terrorist units, most people fitting it with a silencer using its threaded barrel. While some sources call the MAC-10 and MAC-11 machine pistols,<ref>{{cite web |url=http://www.cheaperthandirt.com/MediaPages/ArticleDetail.aspx?mediaid=97 |title=MAC-10/MAC-11 Machine Pistol |publisher=Cheaperthandirt.com |access-date=2009-11-05 |url-status=dead |archive-url=https://web.archive.org/web/20090112062822/http://www.cheaperthandirt.com/MediaPages/ArticleDetail.aspx?mediaid=97 |archive-date=2009-01-12 }}</ref> the guns are also referred to as compact submachine guns.

Since it is difficult to control machine pistols when they are fired in fully automatic mode, some manufacturers developed an "intermittent-fire" setting that fires a burst of three rounds instead of a continuous stream. The first of these guns is the [[Heckler & Koch VP70]], the 70 designating the year of origin; 1970. That is a 9&nbsp;mm Parabellum, 18-round, double action only, select fire-capable polymer frame pistol. It is the first polymer-framed pistol, predating the [[Glock 17]]. The stock incorporates the semi-auto/three-round burst selector, therefore it will only fire a three-round burst with the stock attached. Cyclic rounds per minute for the three-round bursts is 2,200 RPM. Despite the VP70's potential, it was never adopted by the ''Bundeswehr''.

In 1976, a shortened version of the 9&nbsp;mm Parabellum [[Heckler & Koch MP5]] was introduced; the [[Heckler & Koch MP5#MP5K|MP5K]] (K from the German ''Kurz'' = "short") was designed for close quarters battle use by clandestine operations and special services. The MP5K does not have a shoulder stock, and the bolt and receiver were shortened at the rear. The resultant lighter bolt led to a higher rate of fire than the standard MP5 (900-1000 RPM vs. 800). The barrel, cocking handle and its cover were shortened and a vertical foregrip was used to replace the standard handguard. The barrel ends at the base of the front sight, which prevents the use of any sort of muzzle device.

Another popular machine pistol using the three-shot burst system is the 9&nbsp;mm Parabellum [[Beretta Model 93R]]. Introduced in 1979 the Beretta Model 93R, it is a select-fire machine pistol meant for police and military use. It offered extra firepower in a smaller package and is suited for [[concealed carry in the United States|concealed carry]] purposes such as VIP protection, or for [[Close Quarters Battle|close quarters maneuvers]] such as room-to-room searches. A selector switch and the foldable foregrip allow the pistol to fire three-round [[burst mode (firearm)|bursts]] with each trigger pull for a cyclic rate of 1100 rounds per minute. The designers limited it to three round bursts for ease of control. A 20-round magazine and a metal shoulder stock may also be fitted.<ref>{{cite book|last1=Hogg|first1=Ian V.|author2=John Weeks|title=Military small arms of the 20th century|edition=7th|year=2000|publisher= Krause Publications|location=Iola, Wisconsin|isbn=978-0-87341-824-9|pages=63–64}}</ref>

The Stechkin APS made a comeback in the late 1970s when Russian [[Spetsnaz]] special forces units in [[Afghanistan]] used the suppressor-equipped [[Stechkin APS#APB silent variant|APB variant]] for clandestine missions in enemy territory, such as during the [[Soviet–Afghan War]].

The 9&nbsp;mm Parabellum [[Uzi#Micro-Uzi|Micro Uzi]] is a scaled-down version of the [[Uzi submachine gun]], first introduced in 1983. It is 460&nbsp;mm (18.11&nbsp;inches) long with the stock extended, and just 250&nbsp;mm (9.84&nbsp;inches) long with the stock folded. Its barrel length is 117&nbsp;mm and its muzzle velocity is 350&nbsp;m/s. Used by the Israeli Isayeret and the US Secret Service, Micro-Uzis are available in open-bolt or closed-bolt versions. The weapon has an additional [[tungsten]] weight on the bolt to slow the rate of fire, which would otherwise make such a lightweight weapon uncontrollable.

The 9&nbsp;mm Parabellum [[Glock]] 18 is a [[select-fire]] variant of the Glock 17, developed in 1986 at the request of the Austrian [[counter-terrorism|counter-terrorist]] unit [[EKO Cobra]]. This machine pistol has a lever-type select-fire switch, installed on the left side, at the rear of the serrated portion of the slide (selector lever in the bottom position for continuous fire, top setting for single fire). The firearm is typically used with an extended 33-round capacity magazine and may be fired with or without a shoulder stock. The pistol's rate of fire in fully automatic mode is approximately 1,100–1,400 RPM.
