The G39 is Glock's subcompact take on the .45 GAP cartridge, offering a 6+1 capacity in a two-pin Gen3 frame. This example has the Gen3 finger grooves and molded checkering for a secure hold, along with left-side controls consistent with the era, including the slide stop and magazine release.
Its 3.43 inch steel barrel uses Glock's octagonal polygonal rifling, and the provided documentation notes the octagonal profile. The 1:15.75 twist supports the .45 GAP's typical bullet weights while maintaining Glock's known barrel characteristics.
Trijicon tritium night sights are installed, with a Trijicon-marked tritium front sight. These sights provide a bright, durable aiming reference in low light and are a practical upgrade over standard polymer sights.
Markings include "MADE IN AUSTRIA" and "GLOCK, INC., SMYRNA, GA," with the slide roll-marked "GLOCK 39 AUSTRIA 45 G.A.P." These factory stamps and the included test envelope dated 05/17/2005 provide clear identification and provenance.
The package is complete with the original Glock hard case and manual, the captive recoil spring assembly, and seven factory magazines. It is a straightforward, ready-to-go subcompact .45 GAP setup with quality night sights and ample magazines.
