LFA LF AMPX G19X | 9mm | 3.9 in | 17 Rd

The Live Free Armory LF AMPX is an aluminum match-grade pistol built on a Glock 19X-style frame, chambered in 9mm with a 3.905-inch barrel and a 17-round capacity. The design centers on precision machining: a CNC-machined 17-4 stainless steel fire control unit and an aluminum milled frame reduce play and flex for consistent performance. The slide features stepped quad windows, deeper serrations, and an RMR optic cut for direct mount red-dot optics. A compact red-dot such as the Holosun 507K pairs well with the RMR cut and remains under $1,000.
