I just got a Ruger Mark III target pistol in .22lr. It's the stainless Hunter model with 6.5" fluted barrel. Looks and feels great but the only problem was a heavy trigger that measured out at just under 5 lbs. I couldn't see keeping that trigger, especially in a target gun.
Here's the gun out of the box:
I had heard some guys at the local club talking about putting Volquartsen triggers and sears in their Rugers. I have never messed with triggers before but they made it sound so simple I thought I'd give it a try. I found what the ads called "drop-in" kits and ordered the Volquartsen Mark III kit. Here's what I got: Not really what I'd call 'drop-in'.
The instructions that came with the kit were detailed but short and had no pictures or diagrams. I started looking around on YouTube and found several videos about putting in this trigger kit.
I came across two main problems. (1) Most of the videos I found show how to work on the Ruger 45/22 and there are some parts differences between that gun and my Mark III. I had to guess and experiment with the exact placement of a couple of springs. (2) Most of the videos use a Mark II kit with an extra bushing which lets you get rid of the magazine disconnect in theMark III. I had bought the Mark III kit so the parts I had to put back in the hammer assembly were different (and more complicated) than show in the videos. I hunted around and found a bushing that will let me get rid of the disconnect with the Mark III kit, but it didn't get here in time for my project.
The stripped frame and all the parts:
Like I said above, I have never taken any trigger, sear, or hammer assemblies out of a pistol before. It was a slow process and I got frustrated more than once but I finally got there. If I had a video that showed the exact gun and parts I was using it might have been easier. I had to stop and take various assemblies apart several times and chased a couple of parts around the room but I think it's all back together. It dry fires fine and I'll take it to the range tomorrow.
Was it worth it? That heavy 5 lb trigger is gone and the new one measures in at a crisp 2 lbs (actually a couple ounces shy of 2 lbs). It feels great.
While I was at it, I also added some target grips and a spring kit that makes it a lot easier to eject a magazine. The grips came with a stainless extended bolt release that matches the gun better than the blued one that came in the basic kit. Here's the finished project ready for some target practice:
