Ruger Mark IV 22/45 Lite .22 LR 4.4-inch 10-Round G10

Part of Ruger's Mark IV 22/45 Lite family, this semi-automatic pistol is built for accurate, low-recoil .22 Long Rifle performance in a lightweight package. It features a tensioned, cold hammer-forged 4.4-inch stainless steel barrel and a ventilated aerospace-grade aluminum receiver with a factory Picatinny rail. The polymer frame and oversized G10 grip panels provide a secure hold, while the simple one-button takedown enables fast, tool-free field-stripping for maintenance. An adjustable rear sight and fixed front sight complete the sighting system.
