I absolutely love my Ruger Government Target model. I learned how to shoot with that gun. I taught my kids to shoot with that gun and when I have grandkids I will teach them to shoot with that gun.

mm David/ Lee, thank you for posting! This is the BEST tutorial I have seen for how to tune a MK II. Question: Absent some type of jig, is there a preferred technique for keeping things square while stoning; e.g. move part across stationary stone, or move stone across stationary part? Thanks! ***** djoch.... oh, boy! Not everyone can sharpen a chainsaw. My dairyman neighbor once said, “A farmer must know when he can do it. And when someone else should do it." Eyeball + practice. It’s difficult to maintain square contact by hand. I like a vise when it’s available, work by hand when it’s not. Manufacturers tend to get engagement angles right, however going rough on the cut. The rough CONTACT PATCH between hammer & sear causes a glitchy squeeze. If the HAMMER DOG (shelf of full cock notch) is smooth, most likely the pull feels smooth. I’ve worked with files, stones, and belt abrasives to reduce the dog (narrowing contact patch). The hammer may be worked by hand on a stone or diamond-impregnated steel plate on a bench or firm surface. I follow the radius of the hammer to reduce the dog (the sear follows this arc on reset). While the factory parts may (or may not) have some roughness, the parts are cut square, and it is critical to ENGAGEMENT & RELEASE that stock removal parallels axis of rotation. To dress the notch, I fold fine emery paper over a thin knife blade, angle the blade as though to slice through the hammer pivot hole, and stroke back and forth. As square to hammer as possible. Task here is to smooth the dog, or take-up surface----not change its angle. A few strokes requires a new fold of emery paper. The key to trigger work is patience, which includes frequent assembly to dry fire. David Bradshaw |

kgb.... clever little fouling deflector. How does that not interfere with the magazine? David Bradshaw It sits in the space ahead of the magazine, when the mag is inserted the front of it is slightly higher than the deflector as well. I don't remember who made them but believe they are no longer available. Some have made their own version, here's how a contributor over on Rimfirecentral did one with a slice of pop can www.rimfirecentral.com/threads/blast-shields-101.869866/#post-8241538 |

Guy on Rimfire Central says, with deflector in frame he cleans trigger group very 5,000 rounds; instead of at 500 rounds. Fired some old Remington 40 grain Round Nose ammo recently. An appalling cake of what appears partially burned powder & wax. Cleaned pistol, including firing pin----which a deflector wouldn’t help. Rimfire ammo ranges wide from filthy to relatively clean. In nature of design, a blowback autoloading mechanism invites fouling into breech area. Pressure evacuates rearward as well as forward. In development of the S&W Model 41 .22 pistol, clearance between top of slide and “topstrap” intended to prevent jamming from fouling. A sawtooth pattern across the top of the slide intended to promote reliability. I was told by an old mentor Hartley Perry Smith, aka “High Power” Smith, that the first production M-41 slide lacked clearance to prevent fouling stoppage. One advantage of learning the trigger on the Ruger is learning disassembly-reassembly through practice. Familiarity replaces intimidation. In my experience, familiarity does not breed contempt, it breeds respect David Bradshaw |
