The Gen5 G17 platform delivers practical upgrades including a flared magwell, ambidextrous slide stop lever, and a reversible magazine catch. The full-size black polymer frame features the Gen5 texture for a secure hold and an accessory rail for mounting lights or lasers.
The slide wears a matte black nDLC finish with both forward and rear cocking serrations. It is cut for Glock’s Modular Optic System (MOS) and comes with the MOS cover plate installed, making it optics-ready from the factory.
Its 4.49-inch Glock Marksman Barrel is cold hammer forged with enhanced polygonal rifling and a revised crown, designed for consistency and long service life. Chambering is 9mm Luger, and the action is short-recoil, locked-breech, striker-fired.
Factory Glock 3-dot night sights are installed, with the rear marked 6.1 for a clear, consistent sight picture. Capacity is 17+1 (model specification), and this example includes one 17-round magazine.
This pistol also features tasteful performance-oriented touches: an aftermarket skeletonized trigger shoe with a safety tab, and an upgraded guide rod. The frame bears a U.S.-made marking from Smyrna, GA, adding useful provenance for buyers who track origin details.
