The Karabin samopowtarzalny wzór 38M (Kbsp wz.38M self-repeating rifle Model 38M), was a prototype Polish 7.92mm semi-automatic rifle used by the Polish Army during the Invasion of Poland of 1939.
History
The rifle was designed by a Polish engineer Józef Maroszek (1904-1985). He was known mainly as a designer of the Polish anti-tank rifle wz.35 "Ur". Maroszek was one of the three winners of Poland’s 1934 self-loading rifle trials. Several prototypes and pre-production samples of his rifle were manufactured from 1936 to 1938.[1] After a Polish army order was received, small scale production began in 1938. It is believed only about 150 rifles of this pattern were completed before the German invasion of Poland. Production was not resumed under the German occupation. The wz.38M rifles were manufactured by the Zbrojownia Nr. 2 (Arsenal No.2) in Warsaw (Praga). Barrels were supplied by the Panstwowa Fabryka Karabinow (State Rifle Factory) in Warsaw.
The highest serial number observed is 1054 (it is assumed numbering started from "1001", not counting the prototypes and pre-production examples).[2] The decision was made to begin serial production of the rifle at the Fabryka Broni arms factory in Radom in 1938. However, it is unclear if any rifles of this pattern left the Radom factory before the German invasion (all the surviving examples display Arsenal Nr. 2's "Zbr.2" markings). Maroszek stated he had seen a group of German soldiers armed with wz.38M rifles in occupied Warsaw. This is perhaps the only indication Maroszek rifles were reissued to Nazi forces.
The rifle is gas operated with the gas tube located under the barrel. It features a Browning/Petter system in which the bolt tilts up to lock; in the case of the Kbsp wz.1938M, against the front edge of the ejection/loading aperture in the top of the receiver.[3] It has a ten-round non-detachable magazine loaded from Mauser stripper clips. The safety lever is located on the right side of the receiver, just above the trigger. The rifle has a Mauser-style tangent leaf rear sight graduated from 300 to 2,000 m (330 to 2,190 yd). The bayonet lug accepts a standard Polish issue wz.29, and the barrel is equipped with a muzzle brake to ameliorate recoil. For a pioneering self-loading rifle, its design is strikingly advanced in its simplicity and functionality; for example, it's composed of several sub-sections interlocked by a single removable steel pin, and thus can be disassembled in moments. When the last round is fired, bolt is locked back. Rifle has also interesting function similar to Czech ZH-29, where if the gun is loaded with charger clips the bolt can be released into battery with trigger pull. There is also a non-reciprocating charging handle located at the right side of the rifle. Today, this is a difficult to find military rifle on the collector market. There are only nine known examples in collections around the world[citation needed] (1. Polish Army Museum, Warsaw, Poland, deactivated; 2. Central Armed Forces Museum, Moscow, Russia; 3, 4, 5, 6, 7, 8. private collections in the United States; 9. private collection in Germany). The known serial numbers are: 1014, 1017, 1019, 1027, 1030, 1040, 1048, 1054. (The Russian museum and the Ohio collection rifles serial numbers are unknown.)[citation needed]
In April 2017, serial number 1048 was acquired at auction by the Polish government for $69,000.[4]
Relation about combat usage
According to the Maroszek relation, while personnel were evacuating from Instytut Techniki Uzbrojenia (Weaponry Technology Institute) the train they were traveling in was attacked near the city of Zdołbunow by two German warplanes flying at low altitude. As he states in his memoirs, Maroszek kept shooting through the window by his wz. 38M rifle, eventually killing the gunner and wounding the pilot of one of the planes, forcing it to land.[5]
