Glock G39 Gen3 .45 GAP Subcompact with Extended 4 in Barrel, TG-H3 Tritium/Fiber-Optic Sights, Nightstick TSM-12G Light/Laser, and Mixed-Capacity Magazines
This Austrian-made Glock G39 Gen3 in .45 GAP is a customized subcompact configured with an extended, non-threaded ~4 in steel barrel, TG-H3 tritium/fiber-optic sights, and a Nightstick TSM-12G light with green laser. It includes both extended and subcompact magazines for capacities up to 10+1, plus the original Glock-marked barrel, factory case, and manual. The setup offers a distinctive extended barrel configuration while keeping the compact Gen3 form factor.
The Gen3 subcompact polymer frame features finger grooves and no integral accessory rail. The slide and chamber are marked "GLOCK 39 AUSTRIA 45 G.A.P." and ".45 G.A.P." respectively, with Glock proofing present. An importer mark is present on the frame, reflecting its Austrian origin and U.S. importation. Note: The installed slide/upper is a non-matching replacement; the frame and original Glock barrel are serialized PTX105, while the installed slide’s breech-block shows L43400.
Extended Barrel: An extended, non-threaded barrel (approximately 4 inches) is installed, increasing the overall length compared to the standard configuration. The original Glock-marked factory barrel is also included, giving you both the extended setup and the option to return to the standard barrel if desired.
Sights and illumination are set up for visibility in varied lighting. The installed TG-H3 tritium/fiber-optic 3-dot sights provide bright aiming references, and the Nightstick TSM-12G light with green laser is mounted to the pistol for immediate target identification and an auxiliary aiming point.
Magazine flexibility is a highlight of this package. It comes with two 10-round extended magazines that enable a 10+1 capacity, plus three 6-round subcompact-length magazines. A palm swell grip adapter is packaged for those who prefer a fuller grip profile on the subcompact frame.
