Item Description
Bryant Ridge Auction Company is pleased to present this sought after semi-auto pistol today for a penny start auction, this is the Remington UMC Model 51!
Introduced in 1918, the Model 51 was developed from patents and designs from John D. Pederson of Pederson Device and Irwin-Pederson fame as a hesitation-locked blowback semi-automatic pistol with multiple overlapping safety features and good ergonomics. The serial number stamped on the left side of the frame has a "PA" (Pedersen's Automatic) prefix except on very early models. When the pistol was first marketed in 1919 the top of the slide was stamped with the two-line inscription: "THE REMINGTON ARMS UNION METALLIC CARTRIDGE CO, INC. REMINGTON ILION WKS. ILION, N.Y. U.S.A. PEDERSEN'S PATENTS PENDING."
"PA23" is know to be one of the earliest PA prefix examples and this example holds serial number "PA63"!

Bryant Ridge's Analysis:
The gun has three safeties: a thumb-operated safety, a grip safety, and a magazine safety. The grip safety locks the disconnector, locks the sear in the hammer notch, locks the slide, and serves two additional functions. Since the grip safety does not pop out unless the gun is cocked, it acts as a cocked weapon indicator. It also serves as a lock open device for the slide if it is engaged when the slide is retracted. Squeezing the grip safety with the slide locked open will cause the slide to close and, if a full magazine has been previously inserted, a round will be chambered. The thumb safety cannot be engaged unless the hammer is cocked, and when in the safe position it locks the grip safety so it cannot be disengaged.
Interestingly enough, the thumb safety does not appear on the original patent drawings, though it does appear on all the known prototypes. Remington advertised that the gun could be carried safely with only the grip safety in operation, but the thumb safety could be utilized by those who preferred a more positive lock. The Model 51 also has a magazine safety which prevents it from being fired when the magazine is not inserted. The magazine safety does not appear on any of the known prototypes.
The unique locking mechanism of the Remington 51 is rather difficult to describe in words. It has been labeled as a “momentum block” system and as a “blowback/recoil” system, in an effort to differentiate it from a simple blowback action, a delayed blowback action, or a standard locked recoil action. R.K. Wilson considered it a type of delayed blowback mechanism, and that seems reasonable to me, though others may certainly disagree. The Remington U.M.C. company, in one of its advertising brochures, stated: “Breech remains positively locked until bullet has left the muzzle--not a blow-back action.”
The gun consists of the usual receiver and slide components, but the breech block is separate. Sometimes the breech block is referred to as being in two parts, the rearmost portion that supports the rear of the firing pin being integral with the slide. But the moveable portion is independent of both slide and receiver, and since it contains the firing pin, firing pin spring, and the extractor it is usually referred to as the breech block. When recoil begins, the slide moves toward the rear. The breach block remains against the back of the cartridge until the slide moves backward approximately 0.083 inches. The slide continues its rearward motion for a further 0.2 inches, whereupon the moveable portion of the breech block is lifted out of engagement with the receiver and effectively becomes part of the slide as it recoils. The cartridge is ejected in the usual manner; a new round is stripped from the magazine and chambered by the returning slide. An advantage of Pedersen’s moveable breech block design is that it allows for a lighter slide than a straight blowback operated pistol, and hence an overall lighter weapon.

Bryant Ridge's Analysis:
The Remington Model 51 was designed by John D. Pedersen prior to the First World War. The first patent application on the gun was filed in 1915. In 1920, seven patents were issued for the weapon. Six went to John Pedersen, and one went to Crawford C. Loomis, both employees of the Remington Arms Company. Between 1921 and 1926, an additional 25 patents were granted for various aspects of the gun’s mechanism, most to Pedersen. Many of the patented mechanisms were never utilized in a production gun.
One has only to hold the Remington 51 to feel its quality. The first thing you notice is how well the grip fits your hand--the result of extensive testing with hand molds to determine the correct size and shape for the average hand. Similar effort went into calculating the correct grip angle to allow the gun to point naturally. Very few guns feel so much like an extension of the hand as does the Remington 51. W.H. B. Smith says: “With the sole exception of the Luger, and the new German Walther P38, the Walther PPK, Sauer-38 and Mauser HSc (all foreign developments) this Remington 51 is probably the best-balanced, most-instinctive-pointing pistol ever made.” Some of the Remington advertising went so far as to describe the pistol as “self aiming.” R.K. Wilson says the Remington 51 is “...in the opinion of many authorities, the best pocket self-loading pistol ever designed...”
