CZ 52
The CZ 52〔http://www.makarov.com/pdf/cz52d.pdf〕 (also known by the Czechoslovak military designations vz. 52,〔Předpis pro výcvik ve střelbě - 7,62 mm pistole vz. 52, Pěch III-140, Ministerstvo národní obrany, Praha, 1953〕 for "model of 1952", and CZ 482) is a semi-automatic pistol designed by two brothers, Jan and Jaroslav Kratochvíl, in the early 1950s for the Czechoslovak military. Around 200,000 vz. 52s were made by Česká Zbrojovka in Strakonice from 1952 to 1954.〔 The vz. 52 replaced the 7.65 mm Browning caliber (.32 ACP) Vz.50, which had acquired a reputation for unreliability and was underpowered for its role as a military service sidearm. After 30 years of military service, the vz. 52 was eventually replaced by the 9×18mm Makarov caliber vz. 82.
==Description==
The CZ 52 pistol is a roller-locked short recoil–operated, detachable box magazine–fed, single-action, semi-automatic pistol chambered for the 7.62×25mm Tokarev cartridge (the gun was originally designed for 9 mm Luger caliber but due to political pressures had to be redesigned for the then-standard Soviet pistol cartridge). It weighs approximately two pounds unloaded. Military models feature either a parkerized finish or a gray oxide coating, while some CZ 52s were arsenal reblued in the 1970s. These re-finished guns are usually marked as such.
Ergonomically, the grip of the CZ 52 is long when measured from front to rear and slim from side to side with a low "hump" which meets the web of the hand at the rear. This causes the bore axis to sit high above the grip, resulting in very strong felt recoil. Due to its high muzzle velocity and projectile shape, certain higher pressure FMJ ammunition fired from the CZ 52 pistol will penetrate the lower rated NIJ IIA ballistic vest, but is stopped by a standard police issue NIJ II or better ballistic vests,
