Lists on the subject

The gun Remington 51 (also Remington Model 51 ) is one of John Pedersen developed and Remington UMC produced automatic pistol with a delayed blowback . About 65,000 pieces were made between 1918 and 1927.

construction

The Remington 51 pocket pistol was designed for the American civil market and was initially only produced in .380 ACP ( Series of 1918 ), from 1921 also in .32 ACP ( Series of 1921 ). John Douglas Pedersen (* May 21, 1881 - May 23, 1951) began developing the pistol before the First World War , and filed the first patent application in July 1915. What is remarkable for the time is that the construction works entirely without screws . The Remington 51 had an internal hammer and a single-action trigger . It had a manual safety lever, an automatic magazine safety (prevents the triggering of a shot when the magazine is removed) and a grip safety . The latter is a multi-purpose control element that also serves as an actuator for catching the sled. Since it only emerges from the handle when the weapon is cocked, it also functions as a status indicator for the concealed internal hammer.

Remington undertook extensive experiments with wax impressions in order to find the most ideal, ergonomic handle shape possible . Due to its good German characteristics , the company advertised the Reminton 51 as " self-aiming ". The delayed closure also minimized the perceived kickback, which in turn had a positive effect on the shooting precision.

Overall, the pistol is significantly more compact, flatter and also slightly lighter than its contemporary competitors in the .380 ACP caliber - but the weight advantages were more evident in the larger 53 model. Commercially, the Remington 51 was not a great success, although the onset of the global economic crisis also played a role.

Clasp

With the delayed mass lock (English: hesitation lock ) of the Remington 51, the slide and locking piece initially move back together by 0.083  inches (2.11 mm) until the actual, independently movable locking block is braked by a locking shoulder on the handle. The slide accelerated by the impulse then moves further backwards against the force exerted by the locking spring due to its inertia , whereby the locking block is raised and can move on together with the slide. With self-loading weapons, a breech block is used to delay the repeating process long enough after the shot has been released until the projectile has left the barrel and the system pressure has dropped to a safe level. With simple, unlocked spring-mass closures , this is achieved solely through the inertia of the closure piece, which is why these are only suitable for relatively weak cartridges.

Due to the delayed locking of the Remington 51, the breech and the entire weapon can be made more compact and lighter. In addition, it enables the use of a fixed barrel, which enables a low barrel axis and increases the weapon’s intrinsic precision. Remington advertised the system as a "breech ... positively locked" system , which is actually not entirely accurate. However, the system designed by Pedersen is much simpler than traditional interlocks such as the Browning system .

Remington 53

The Remington 53 pistol (alternative designation: Remington Model 1917 ) was a military variant in the larger caliber .45 ACP . It was 210 mm long and weighed around 907 g unloaded, the magazine capacity was 7 rounds. The weapon differed from the Remington 51, among other things, by an external hammer, it also had a conventional slide stop lever and did not have manual safety devices. It was lighter and more precise than the Colt 1911 and had fewer springs and moving parts. In addition, due to the delayed mass locking, the perceived kickback was noticeably less. The pure manufacturing costs of the Remington 53 should be well below those of a Colt 1911.

The pistol passed the US Navy procurement tests conducted at the Savage Arms rifle range in Utica in June 1918 , after which Remington requested an offer for 75,000 pistols. Although the company improved its offer in July 1919, the weapon was no longer introduced after the end of World War I, not even by the US Army , which had carried out appropriate tests in 1920. The only known prototype is now in the Remington Factory Museum.

Effects

Pedersen's delayed mass lock was also used on the SIG MKMO submachine gun developed by Gotthard End in 1933 . Pál Király , who previously also in the Swiss Industrial Company had worked (SIG), developed at the end of the 30's have very similar submachine gun Danuvia 39M with hebelübersetztem blowback ( lever-delayed blowback ). This is based on a patent by Pedersen from March 1922 for a variant of the Remington 51 that was not built.

In January 2014, Remington presented the sub- compact R51 self-loading pistol in 9 × 19 mm caliber with a Pedersen bolt.
