Trigger pull too light

[AndyJay]

After replacing my hammer, I noticed that the pull had lightened considerably. At first I thought this was a good thing, but several unintentional "double-taps" have shown me otherwise. (The shots did go nicely on-target, but geez, that's unsettling.)

So, what is it exactly that controls the amount of pressure needed to release the hammer? Staring intently at the pistol while chanting "Om" has not yielded answers, nor has reading goat entrails, which is odd, because those are my favorite methods for solving difficult computer problems.

Is this just a simple matter of a spring, or are we talkin' new sear and whatnot?

Thanks very much for your attention,

Andy

Bending the left and center legs of the sear spring will alter the pull weight. I was working this the last couple of days. My gun doubled, then quintupled (I had to test it two or three times, to make sure it actually was malfunctioning. All of my friends wanted to test it as well, but I digress), and while bending the sear spring wasn't the proper fix, it did add about a pound to the pull weight. I placed the spring, on edge, on a piece of paper, and traced around the outside, so I had a reference for how much I was bending. I bent both legs back (away from the sear and disconnector) about 1/8", measured at the tips, and that took off the previously-added pound. I've noticed that after some cycles, the pull weight "settles down" some, so it may take a bit of bending, dryfiring, bending, etc. to fine-tune it. I like a 3.5# trigger, with a snappy reset, so there's plenty of adjustability, but if you are fiddling in the 2#-3# range, tread very carefully.

Any time you change the hammer/sear pair, they will always needs to be fitted to each other.

I would say it's an engagement problem over a sear spring tension problem.

Thanks very much for sharing your experience with me, RickB and Wichaka. I will try changing the tension on the sear spring, though I suspect Wichaka may have pinpointed the problem-- when I changed the hammer, I left the original sear in place. Completely ignorant on my part, but hey, that's how one learns, no? This may wind up being a gunsmith job, which I try to avoid (not so much because of the expense, but because I like the feeling of having done something myself-- well, that and I hate to part with the pistol for long periods of time).

With any luck, my terrible job of reinstalling the flat spring after putting on the beavertail may have resulted in a flattened-out spring (I managed to hook the top under the sear a couple of times), so I'll definitely check that out first before getting a sear and making hard decisions.

Thanks again!
