I replaced the stock sear on my Mk III 22/45 with a VQ sear. Previously I had installed a Clark Mk II hammer bushing. I had expected to see an improvement in the trigger. After the sear replacement, I have significantly greater trigger pretravel and very little, if any, reduction in trigger force. This is probably not the right words, but you all know what I mean.

I probably did something wrong. What?

Hi oldpal, I'm surprised at the lack of reduction in trigger force. Mine dropped several pounds

If your machine saavy, there are pictures of several aftermarket pretravel screw installations done to take it up...

I'll leave any more detailed idea's up to BE and the others...

What you describe is very rare if you did not get a lower trigger pull. VQ uses a more relaxed angle which lowers the force. Did you lay the two side by side to see what the differences are.

Was this a bargin sear or factory fresh one? Is the sear face polished?

It would be rare if your trigger didn't drop pull weight with the VQ seear. Unless your old trigger was already near 2 lbs before you changed the sear.

You know, the trigger pull weight on my pistol is better than I had thought, but I am far from an expert or experienced in triggers. I don't have a scale and have been just "feeling" it and it was probably not to bad originally. Anyway I shot it yesterday comparing it to a Ruger standard auto pistol that I also thought had an OK trigger. The 22/45 with the VQ sear and Clark bushing was much better. I guess the next thing I need to do is get a VQ trigger and work on the pre-travel. The shipping and handling from Midway is killing me with so many separate orders.

You can add a pre-travel to your factory trigger. It's not hard to do, here is a link on one way of doing it. http://www.guntalk-online.com/forum/viewtopic.php?t=651

If you do this to a MKIII you need to file the nub off the back of the trigger that is suppose to seat the mag if not fully seated. This function does not work unless you think a 50# trigger is normal. So it's no loss.

blue, thanks for this info. If I had the equipment to modify the stock trigger I might try it. When I had access to a complete instrument shop this job would have been easy, but not now. A new VQ trigger is simpler.
