The H/47 submachine gun (Czech: Samopal H/47), also known as the ČZ 246, is a Czech prototype submachine gun.

History[edit | edit source]

Designed from 1946 to 1947 by Czech engineer Jaroslav Holeček, an employee of CZ, the H/47 was one of a number of submachine guns tested by the Czech which incorporated the idea of having the center of gravity of the magazine as close as possible to the gun's bore axis.

The first prototype was tested alongside two similar designs, the ZB 47 and ZK 471; the initial prototype performed very poorly (in fact, the weapon had to be manually cycled each time the weapon was to be fired) and was rejected outright. Despite the rejection, work on the weapon continued, so an improved design was drawn up; as with the older H/47, the weapon was designed by Holeček, but this time he was assisted by Jiří Čermák (who would later join CZ's rival company, ZB).

The newer design was a far cry from the original design in terms of appearance; it was noted to have far better performance than the older prototype. Despite its performance, a report was later published by CZ stating that the development of both prototypes would halt entirely due to the weapon not functioning as intended.

Both prototypes have been acquired by the Czech Military History Museum in 1995 from ZB.[1][2]

Design Details[edit | edit source]

A very strange and unconventional submachine gun, even by modern standards, the H/47 is a blowback-operated submachine gun with a very strange curving segmented bolt. The weapon's bolt curves downwards in the direction of the receiver, with the 43-round magazine fed into the weapon through the stock.

The weapon's charging handle is a normal charging handle on the first prototype and a crank on the second prototype; the charging handle is on the right side on both weapons. Both H/47 prototypes are very different in appearance; the first prototype has a perforated barrel shroud and a notable lack of wooden furniture while the second prototype drops said shroud altogether, with prominent wooden furniture.[1][2]
