The .45 G.A.P. (often called the .45 "GAP") pistol cartridge was designed by Ernest Durham, an engineer with CCI/Speer, at the request of firearms manufacturer Glock to provide a cartridge that would equal the power of the .45 ACP, have a stronger case head to reduce the possibility of case neck blowouts, and shorter to fit in a more compact handgun. G.A.P. is an initialism for "Glock Automatic Pistol", and the .45 G.A.P. is the first commercially introduced cartridge identified with Glock.
