    I just took my new 22/45 Lite (MK III) out of the box and noticed that the trigger is really wobbly. It almost looks like the factory pin is too small. Is this right?

    The left side pin hole measured .158" and the right side was .166" diameter. The pin diameter was .155" (5/32 is .156"). So, basically the holes are oversize (which I already knew). The side-to-side clearance on my MK II is about .006" and on the MK III it's about .050". I also tested the trigger pin and holes on my MK II and they were .155" for the pin and the holes gauged.156" or so. The pin, therefore, is not the problem. I could also not get a #22 drill bit (.1570") through the hole in the trigger. Therefore, the trigger is in spec.

    For the machinists out there, I was using drills from my drill indexes and trying to insert them backwards into the holes. The pin was measured with calipers.

    Here's my issue. If I send it off to Ruger, are they going to fix it or are they just going to replace the frame with another built on the same tooling?

    Ruger's QC has went downhill on the MK3's big time. We have had a lot of issues pop up over on RFC. Send it back, they eventually will make it right.

    I read through several of the problems, but this problem did not seem to be covered.

    Got no idea.... If I owned the same ruger I'd test it myself, but I don't. I'd send it back. That trigger side to side wobble would annoy me while shooting.

    Will be watching this thread......hopefully ill learn something.

    I have a #19 drill bit and plan on reworking it sometime this week. Walked around a gun show and picked up ever MK III 22/45 I could find. EVERY ONE OF THEM had the same issue.

    How about shimming the trigger to eliminate the wobble?
    Adding a thin, large diameter washer between trigger body, where the pin goes through, and the inside of the frame might do the trick.
    If there's not much space there, a suitable shim could be made from scratch, from shim stock.
    Just a thought.

    After reading your post I checked mine and discovered it has a little side to side movement too. I never noticed it before. Not going to mess with mine since it doesn't bother me and shoots just fine.

    Well, it's not the side-to-side play as much as it is the hole wobble. If you look closely at the pin, it wobbles around in the hole. I bought some commercial shims and I will be shimming it as well. The old pin will be cut down so I can use it as a slave pin for assembly. There will be a video. I've got the stuff to do it with, just need the time now.
    I didn't see too many posts about this, so I figured the majority of folks did not notice or care. I've shot probably 100,000 rounds or so through the MK-II's that I own, so I am somewhat familiar with how the trigger is supposed to feel. It will end up feeling better, I know, but I'm not expecting the angel chorus to start singing when it's done.

    Fixed

    Well, after lots of thought, a few shims, a drill bit, and some time, I was able to reduce the wobble + side-to-side play about 95%. MUCH MUCH better now and I'm really loving the gun now. Wish it had come from the factory WITHOUT the LCI, WITHOUT the Mag Disconnect, and with properly toleranced parts... but in the end, I made it the gun it should have been. I knew what I was getting into with the LCI and Mag Disconnect, but the trigger wobble is just shameful.

    TLDR? Then just watch the video: :D
