Ruger® redesigned the platform of their famous 22 pistol to make the Mark IV™ 22/45™ LITE Semi-Auto Rimfire Pistol with a simple rear-mounted takedown button and a frame-mounted pivot pin that eliminate the complexities of field stripping previous models. The Mark IV pistol disassembles and reassembles easily, allowing proper chamber to muzzle cleaning. The 22/45 LITE utilizes a single-piece, aerospace-grade aluminum receiver with a ventilated barrel shroud that houses a tensioned stainless steel barrel. The muzzle is threaded at 1/2''-28 for attaching aftermarket suppressors, and it's fitted with an aluminum thread protector. The aluminum receiver coupled with a Zytel® polymer grip frame results in a super lightweight, full-sized pistol. The top of the receiver has a Picatinny rail mount if the shooter desires to use optical sights. A manual, ambidextrous thumb safety locks the sear, while allowing the pistol to be loaded and unloaded when engaged, and a magazine disconnect prevents the pistol from firing once the magazine is removed. The Mark IV model does not have a loaded chamber indicator on the side of the receiver or an internal key lock.
