Colt 22 Scamp  Experimental Prototype

               The Colt "22 SCAMP"
Pistol and Cartridge were one of a few prototype cartridges and
pistols tested to replace the M1911A1 in the early 1970s.
As the requirement for accuracy led to the design of the 22 Scamp Cartridge,
it was found the 5.56 caliber rifle cartridge was too hot for a handgun, and
the 9-mm parabellum round had too relatively heavy a recoil.
The design team settled on a rimless version of a 22 Hornet as the basis
of their new cartridge, leading to the "22 Scamp" design.
Despite positive reviews by military personnel who got to test the
"Scamp" Prototype, it was rejected, as the military decided they were
not looking to replace the M1911A1 pistol at the time because they were already
working on a parallel development - the Personal Defense Weapon.
For the above reasons the gun and cartridge where not put into
production and this experimental prototype cartridge is Truly Very Rare.
