The Ruger MKIV competition .22lr is the latest semi auto come out of one of America's favorite gun companies. The all stainless steel frame and slab side 5.5" barrel balances like a dream, and the adjustable rear sights are simple to sight in with a variety of ammunition. Clean crisp trigger breaks clean and the thumbrest style checkered laminate grips fit the hand like a glove. A major upgrade to the MKIV over previous generations of Ruger .22lr handguns is the greatly enhanced takedown. Unlike older models where breaking down a Ruger MK series pistol can be tricky to say the least, the MKIV version has a hinge pin on the front of the receiver and a simple button on the rear will pop the handgun open for cleaning without need for tools. The magazine on the Ruger MKIV .22lr pistol drops free for smooth reloads and enlarged bolt ears make for easy manipulation.
