If your windage error is 2 inches at 22 yds that would indicate a 0.002 inch adjustment. Please don’t try to get that with a bigger hammer!!! We use jack screws for that sort of movement. But as you noted the trigger pull is rougher so when you fix that compared to your other pieces, the 2” problem might go away. Shoot a few rounds with your other hand and see if the POI moves?
Another check you can do is insert a proper bore rod and survey the bore alignment to the sight alignment. Some of the knockoff 1911’s use a lock screw from the bottom up to pin the rear sight. Any sign of a lock screw?
I don’t have a jack screw. :)
Old school. Drift the sight left or right. Would be a lot easier if it was adjustable. But the gun wouldn’t have been $349.99 if it had that feature. No sign of a lock screw from the bottom. I think they legitimately did it close to spec for the 1911A1. I will pull the slide and double check, but I don’t think they could even do that and retain all of the 1911 design.
Actually, 2 inches at 22 yards isn’t bad really. Trigger is crisp but higher weight than I’m used to. It has a good break.
I’ll give that other hand trick a try. Could be the heavier trigger has me pulling a little though I did a lot of making sure that I’m not doing it. Doesn’t mean I’m not though.
Interestingly, when I pulled out my Colt Government, it was delightful. I worked the trigger on that one with some polishing, though it was good out of the box anyway. I have the proper stones and jigs for doing the sear, but in this case, I just polished with a fine ceramic stone, to remove any uneven surfaces, taking care to not change any angles.
I have to mention that I do enjoy tinkering with things of this nature.
I also should mention that I incorrectly reassembled the trigger mechanism on an AR-15 many years ago, which resulted in it firing 1 shot, and then refusing to fire again. A learning experience - LOL.
Anyway, I’ll be toying with this one for a while. It seems to be of very high quality, given the price, just lacking the high-end finish and features. If it works with standard 1911 parts, it could easily be turned into a really nice shooter.
