Automatic pistol launches 9mm Barabellum pistol and revolver launches.38 special revolver, which has been favored by police all over the world. When Glock 17 pistols were born, they were even more popular all over the world, but an obvious problem also appeared-these standard (full-size) automatic pistols or revolvers are bulky and often inconvenient for secret police or agents wearing plain clothes to carry. As a result, many manufacturers have introduced small 9× 19mm automatic pistols, also known as "palm thunder". These small automatic pistols are either independently designed or developed on the basis of standard models.
China CS/LP5 automatic pistol
CS/LP5 automatic pistol, also known as NP42 mini automatic pistol, was improved on the basis of NP42 automatic pistol (Foreign Trade 92-9) by Chongqing Changfeng Machinery (merged with Construction a long time ago). Mainly in order to shorten the length and reduce the volume, the single-row magazine is used to load ammunition, which is more convenient for concealed carrying.
The internal structure of CS/LP5 automatic pistol is basically the same as that of NP42 automatic pistol, which adopts short recoil automatic mode and spin lock mode. The gun is fired by hammer rotation, and single/double action shooting can be selected as required.
The caliber of CS/LP5 automatic pistol is 9mm, and 9mm DAP92 series pistol or 9mm Barabellum pistol can be used (in essence, the former is a variant of the latter, and the casings of both are 19mm long, but the former is longer). The gun has a total length of 160mm and a barrel length of 90 mm, and seven single-row magazines are used for ammunition supply. After loading the empty magazine, the total weight of the gun is 0.64kg.
In terms of safety, CS/LP5 automatic pistol is equipped with compulsory insurance, as well as trigger insurance and fall insurance (and an insufficient insurance). The compulsory safety of the gun adopts symmetrical design, which can be easily used even by left-handed people.
Austrian Glock 26 and Glock 43 automatic pistols
Glock series automatic pistols have been welcomed by police all over the world since their birth. On the road of miniaturization, Glock has also made great efforts, such as Glock 26 and the latest Glock 43.
Glock 26 automatic pistol is a 9× 19mm caliber automatic pistol, with a total gun length of 165mm and a barrel length of 87mm. After loading the standard empty magazine, the mass of the whole gun is 0.6 15kg.

The standard magazine is 15 rounds, and long magazines of 17 rounds or 33 rounds can also be used. In addition, Glock also provides a plus base for these magazines, which can increase the ammunition capacity of two more bullets.
The insurance method of Glock 26 automatic pistol is quite special. It uses "double triggers" to trigger insurance instead of compulsory insurance. The shooter only has a chance to pull the trigger after pulling the safety bump in front of the real trigger. This kind of insurance institution can be said to be controversial, because it may close down because of the linkage.
Glock 43 automatic pistol is a further reduced and slimmer version of Glock 26 automatic pistol. The original Glock 26 automatic pistol adopts double-row single-entry magazine, and the Glock 43 automatic pistol adopts single-row magazine. Glock 43 automatic pistol has a total gun length of 159mm and a barrel length of 86 mm After being loaded into a standard empty magazine, the total gun weight is 0.509kg. The internal structure of the gun is exactly the same as that of Glock 26 automatic pistol, but the volume is smaller. The magazine used in Glock 43 automatic pistol is 6 rounds in a single row, and the plus base can be installed to increase the capacity of 2 rounds.

Small automatic pistol, because of its small size and short barrel, has less muzzle kinetic energy than standard automatic pistol. For example, the muzzle kinetic energy of CS/LP5 automatic pistol is about 400J, which is only 80% of NP42. But it is precisely because of miniaturization that it is easy to carry and can play an unexpected role.
