Trigger replacement

I'm going through my Kimbers adding stuff and doing a bit of customizing and would like to install a smooth trigger in place of the stock serrated one. Are 1911 triggers standard? Is this something I can do myself? Any recommendations?

Yes, it is something you can do yourself and I recommend you buy Jerry Kuhnhausen's books THE COLT .45 AUTOMATIC, VOL. I and THE U.S. M1911/M1911A1 PISTOLS A SHOP MANUAL.

No, not all 1911 triggers are 'standard' - in the sense that you can simply swap the old with a new one.

Yes, you can do this yourself, depending on how good you are at stuff like this, and how well you prep before starting the job.

See the attached picture I put together. The colored arrows indicate most of the places that might need adjustment in order to properly fit a new trigger. Physically installing it will be easy, getting it to work properly is the key.

Depending on the new trigger you get:

- At the red arrows, you might have to remove material/polish this area to get the shoe to clear in the top and bottom of the frame

- At the light blue arrow, you might have ensure that the angle and front to back position is correct

- At the dark blue arrows, you might have to polish the bow surface, adjust the shape of the bow (Brownell's sells a shaping block), or adjust the width of the bow to get the trigger to slide freely in the frame slots

- At the green arrow, you will have to properly adjust the overtravel screw - if not, properly done, it could cause an unsafe condition.

I would recommend that you get Jerry Kuhnhausen's Shop Manual #1 and possibly #2 (Brownell's sells these also) and read up on the subject.

It's not difficult to do, just easy to mess up.

Hope this helps.

I'm not going to work today. The voices in my head told me to stay home and clean my guns (and check the 1911 Forum).
