Remington introduces its R51 pistol, a modern version of the old Remington Model 51 released in 1918.

The original Remington Model 51 relied on a unique type of action created by John Pedersen, a designer best known for the “Pedersen Device” that turned a bolt-action Springfield 1903 rifle into a semi-automatic magazine-fed pistol caliber rifle with a simple bolt change. Like the original, the latter day Model 51′s barrel remains fixed in place. After ignition, the breech block slides slightly backwards before tilting down and out-of-the-way, imparting enough momentum to the slide to carry it through the reloading cycle.
