The G19 Gen4 MOS pairs a 4.02 inch barrel with Glock’s striker-fired Safe Action system in a compact, carryable format. The polymer frame features Gen4 RTF texturing with finger grooves and an integral accessory rail. A reversible magazine catch and the Gen4 dual recoil spring assembly round out the user-focused updates.
The slide is factory-cut for Glock’s Modular Optic System and comes with the MOS cover plate installed. Included MOS Adapter-Set 01 plates with hardware provide the interfaces needed to mount miniature red-dot sights via the appropriate adapter plate.
Ergonomics are easily tailored using the included Gen4 Modular Backstrap System (set of three). Fixed polymer sights are standard, with a white-dot front and a fixed polymer rear notch that provide a clear, familiar sight picture.
Capacity is 15+1 in 9mm Luger, and this pistol includes three Glock OEM 15-round magazines. Also included is a Gemtech 9mm threaded barrel for the Glock 19 (not installed), offering an additional barrel option when desired.
This Austrian-marked pistol features matching serialized slide and frame. Markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." molded into the left side of the polymer frame, the slide marked "GLOCK 19 Gen4 AUSTRIA 9x19," and an "AT" stamp on the barrel.
