Turn your allen screws all the way flush with the edges of the trigger. This allows you to put the trigger through while the gun is still completely assembled. *Note…some triggers are different shapes and may or may not fit through the trigger guard space. Fortunately, Ive been able to get all of mine through that way*.
Slide your new trigger through the front of the trigger frame while the gun is assembled. This step is pretty straightforward. Just remember be careful not to force anything and scratch your anodizing. If it doesn’t slip in that easily, you may need to unscrew your setscrews a tad more.
Replace the trigger pin. Acidcustoms triggers come w/ a trigger pin. Don’t try and use the stock one, I checked….it seems too big to fit through the bearings.
Replace the trigger pin setscrew. I put a small drop of blue loctite on this as well. No need to overtighten it. You might strip your frame if you try to much.
Use your allen wrench to adjust the trigger setscrews. I always adjust the trigger where I want it first….THEN…adjust the activation setscrew.
This may or may not be necessary depending on your trigger style and whether or not you have already adjusted your return stop and it doesn’t require tweaking by luck. I had to adjust it this time, but its still minimal disassembly.
Tweak it to your liking. Probably only need minor adjustments from here. Then you can walk around the house like a dork walking your trigger just to make sure you like the feel of it.
