Trigger Pin Wobble on 22/45. Normal?

[Ghostmaker]

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?

Don't know if that is normal or within factory spec.
But, you can buy all sorts of trigger shim kits from:

Mine will move side to side if you push on it, but it isn't loose by any means. (I have removed the magazine safety.)

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?

That amount of side play doesn't look unusual to me. The trigger pin is positively located by a spring that fits into a groove just where the pin goes into the right side of the frame.

It's a plastic trigger. One of the first upgrades many 22/45 owners make is to install a Volquartsen target sear and adjustable trigger, which fits better and removes the long take-up slack and overtravel.

Well, first of all, the trigger is aluminum, not plastic. Also, the trigger pin is not positively located either side-to-side or 'wobble' wise as the holes are .010" oversize on the frame. Why would I purchase a $50 trigger that would still wobble? I have no intention of purchasing a Volquartsen, but there is nothing wrong with it. The only real advantage is that it gives you pre-travel and over-travel adjustments. Even with the wobble, I do not find the trigger pull objectionable after the slack is taken up.

I have a box-stock 22/45 also, and have found the same about the trigger quality as you have. My trigger pin is locked up tight by that spring. One time when I thought it was loose, it was because I had mistakenly swapped it with the sear pin. I agree, once the slack is gone, the break isn't too bad. Mine breaks at 4.5 lbs. I just remind myself that Service Pistol rules require a 4 lb trigger. My Ruger is a good training pistol. Once I get a target pistol with a good trigger I should shoot great.
