CZ Model Pistol

By E. J. HofFschmidt

The Czech Model 27 pistol has had a short but intriguing history. During the early 1920's, the newly formed Czech army was seeking a military pistol. Around the same time the Mauser firm was experimenting with a pistol designed by Josef Nickl, who had been an assistant to Paul Mauser. The Nickl design featured a locked slide with rotating barrel, and the hammer was external. Lockwork, frame, and magazine were like that of the Mauser Model 1910 Pocket Pistol. Eventually the Czechs were licensed to manufacture this gun. It was issued in 1922 and revised in 1924 to become the standard military pistol. Although the main topic of this article is the Model 27, the Model 24 must be mentioned because it is often mistaken for the later Model 27 gun.

Like the Mauser prototype, the Model 24 is a locked-breech gun with a barrel that rotates to unlock. This feature was dropped in the Model 27, since a simple blowback system is strong enough for the cal. .32 cartridge.

The Model 27 saw wide service before, during, and after World War II, and thousands were brought back from Europe by U. S. soldiers. There are 3 more or less common variations in markings. Late prewar and early wartime manufactured guns are usually blued and well finished and are usually marked "Böhmische WafFenfabrik AG in Prag" along the top of the slide. As the war progressed, efforts were made to increase production by substituting stamped for machined parts. The side-plate, safety arm, magazine catch, and firing pin retainer were all replaced by sheet metal stampings. The trade name was dropped, and the German code letters "fnh" and "Pistole Modell 27 Kal. 7.65" were stamped into the slide. The fine prewar bluing was dropped in favor of the more durable Parkerized finish. Production was- started up again by the Czechs shortly after the end of World War II. These postwar guns are marked "Ceska Zbrojovka-Narodni Podnik" above "Strakonice" which means Czech National Cooperative Arsenal in Strakonice.

As pocket pistols go the gun is simple, compact, and reliable. The sights and grip are good. The efficient Mauser-type safety catch is one of the best features of the gun. Simply cock the hammer and

From the military standpoint it leaves a lot to be desired. So little of the hammer is exposed that it is awkward to cock if the shooter's hands are greasy or wet. The magazine safety is another debatable feature. If the magazine is lost, the round in the chamber cannot be fired. The gun cannot even be used as a single-shot weapon. When the last shot is fired, the magazine follower holds the slide open. This makes it necessary to remove the magazine against the pressure of the spring-loaded slide, which greatly slows magazine changes. The Czechs too realized the shortcomings of the Model 27 and around 1950 replaced it with a double-action pistol greatly resembling the Walther Model PP.
