The G40 Gen4 MOS pairs a long-slide 10mm setup with a 6.02-inch barrel to deliver an extended 8.31-inch sight radius. Capacity is factory-rated at 15+1, and this example includes three OEM 15-round magazines to support range or field use.
The slide features the Glock MOS cut with the cover plate installed from the factory, and it comes with the Glock MOS Adapter-Set 02, including plates, screws, and wrench. The slide has been professionally refinished in a non-black light gray/tan tone for a distinct, durable look.
Upgraded sights include a high-visibility three-dot arrangement: a bright front blade with an orange ring around a green dot, paired with a square-notch rear featuring two green dots. A flat-faced trigger shoe with an integral safety tab is installed for a consistent trigger interface.
The Gen4 polymer frame has a black finish with Gen4 RTF texture and finger grooves, plus the included modular backstrap set with beavertail options for fit tuning. It retains Glock's Safe Action system and trigger safety, a standard left-side magazine release, and an accessory rail.
Manufactured in Austria, this pistol carries the "MADE IN AUSTRIA / GLOCK, INC., SMYRNA, GA." marking and has matching serial numbers on the frame and slide (BHGZ916); barrel unnumbered. The steel barrel uses Glock's hexagonal rifling with a right-hand twist.
