I figured one of each would be fun, although I wavered between two 45 acp guns, as 45 acp would be more saleable?

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.
