Probably a broken record on my part by now, but if you have (or can scrounge) the necessary roll pin punches, and can deal with the microscopic sear spring & plunger, it's a fairly easy installation. Randy's videos really cover it well.
(Just plan on doing the sear and spring/plunger at the same time. IMHO, there's a slight advantage to doing the trigger spring while the sear assembly is out of the gun, too, but not much. You can do the drop safety plunger anytime; getting the rear sight off can be interesting, but I had no problem. I did use a sight pusher, though, but it seemed like it would have been easy enough with just a nylon punch.)
I ended up with a DCAEK on two M&Ps - a Compact and a Full Size. Quite a difference when just the Compact had been done.
(IMHO, any smith ought to be able to do this for about a 30 minute bench charge if he's seen the videos or done it before. 1911 guys also should be able to handle it if they've got the roll pin punch and a magnifier
.... I'm a 1911 guy
and had to rebuild a P3AT a couple times. Close enough.... Or, as I tell people, I usually get the grips back on the correct side of a 1911....
