The Ruger MK IV 22/45 Lite uses a 1911-style grip angle (matching the Colt 1911) and a threaded aluminum Lite barrel shroud that is drilled with lightening cuts and tapped for a suppressor. At 25.4 oz it is significantly lighter than bull-barrel MK IV variants. The grip angle makes it a natural 1911 training companion.
