Who designed the guns used in the "Limited Class" and "Open Class" pistols offered by A & B?
.45 ACP The .45 ACP (Automatic Colt Pistol), or .45 Auto (11.43×23mm) is a handgun cartridge designed by John Browning in 1905, for use in his prototype Colt semi-automatic pistol. After successful military trials it was adopted, along with the Browning .45 Colt handgun, as the .45 M1911 cartridge. The handgun was designated M1911 pistol.
Colt Model 1910 The Colt Model 1910 was a prototype .45 ACP caliber automatic pistol developed by John Browning as an improvement of the earlier Colt Model 1909, which was rejected by the United States Department of War due to the Cavalry's belief that the design was too complicated for use by enlisted men, and because it lacked a safety mechanism.
