The 22/45 Target configuration combines a stainless steel receiver and bull-profile barrel with Ruger’s polymer frame to deliver a durable, full-size .22 LR pistol. The satin stainless finish is matched to a 5.5-inch bull barrel for steady handling.
The Zytel polymer frame uses a 1911-style grip angle with integral polymer grip panels for a consistent hand fit. Controls include a push-button, left-side magazine release and a manual thumb safety, with a single-action trigger.
Target-focused sights consist of a fixed, ramped front and a fully adjustable rear target sight. The Mark II setup provides a last-round bolt hold-open and, true to the series, does not include a loaded-chamber indicator or a magazine disconnect.
This pistol operates on a simple blowback action and is chambered in .22 LR with a 10+1 capacity. It was manufactured in the USA in 1999 and is cataloged as KP512 (Model 00192).
