Ruger Mark II Auto pistol was introduced in 1982. The Sturm Ruger company virtually made its name with its Standard .22 Automatic pistol, which was first introduced in 1949 and has been the firm’s anchor ever since. At the end of 1981, with over one million of this and its target version, the Ruger Mark I sold, it was announced that an improved version, the Mark II, would be marketed during 1982.

The Mark II maintains the same basic form and appearance as its predecessor, a blowback pistol using a fixed barrel and a bolt that reciprocates within a tubular receiver; several parts are, in fact, interchangeable between old and new models.

The changes are minor in form but add up to significant improvements; the trigger has been changed in material and shape, and its pivot system has been redesigned so that it is now possible to retract the bolt to unload or examine the chamber while the safety is applied and with the sear firmly locked; the magazine has been reworked and now accepts 10 rounds instead of the former nine; the rear of the receiver has been cut away on each side so that it is now easier to grasp the bolt retraction ears, and a new bolt hold-open device has been adopted.

The old model used the safety catch as a hold-open device, but the Mark II has a small catch above the left grip which, when depressed, allows the bolt to close after it has been held open by the magazine follower after the last shot has gone.


An impressive weapon, the Ruger Mark II Auto Pistol is available in Standard models with fixed sights and with 4.75 in or 6 in barrel lengths, a Target model with fully adjustable sights and a 6 in barrel, and a ‘Bull Barrel’ model with adjustable sights and a heavy 5 in the barrel.
