Built in the United States, this Gen4 compact 9mm features U.S.-specific roll marks: the frame is marked "MADE IN USA GLOCK, INC., SMYRNA, GA," the slide is marked "USA," and the barrel is marked "US." The barrel hood carries "9x19," a circled "3D," the Glock logo, "US," and the pentagon "P" proof. The barrel also shows a pentagon "P" proof mark.
This example retains key Gen4 updates, including the RTF grip with finger grooves, the interchangeable backstrap system, and an enlarged magazine release. The black polymer frame pairs with a matte black slide and a Glock accessory rail with a single slot for compatible attachments.
Factory Glock polymer sights are installed, with a white dot front and a white U-outline rear. The pistol uses Glock’s striker-fired Safe Action system and a 4.02-inch steel barrel. The bore is exceptionally clean with strong polygonal rifling.
A purposeful setup, it comes ready with eight factory magazines (three 18-round extended and five 15-round), plus an SLR-branded magazine well funnel that is neatly fitted to the frame. The package is rounded out with the factory hard case, owner’s manual, and two non-beavertail Gen4 backstraps.
