The .45 G.A.P. Trio is made up of the GLOCK 37 (G37) and the newly released GLOCK 38 (G38) and GLOCK 39 (G39). The G38 and G39 are almost duplicates of existing compact and subcompact models with a few significant changes. Starting with the receiver, the current "dog leg" .45 caliber ejector has been used, as has the extended slide stop lever, and the redesigned trigger bar of the G37 has been used. The G38 also has light rails that accept all GLOCK Safe Action Tactical Lights. As to magazines, the G38 holds eight and the G39 six rounds in a semi-staggered column.
