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.
Revolver A revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. Revolvers might be regarded as a subset of pistols, or as an equal-ranking subset of handguns, distinct from pistols. Though the term "revolver" usually only refers to handguns, other firearms may also have a single-action revolving chamber. These include some models of grenade launchers, shotguns, and rifles. These are different from other firearms with revolving chambers, such as miniguns and gatling guns in that revolvers typically require the hammer to be re-cocked with each shot and require manual reloading, while miniguns are semi-automatic or automatic and often belt-fed.
