YMMV Greatly. I posted this some time ago on another forum re the concept of the .25 Trigger Job. I re-posted it here in response to an inquiry re the same in 2017.
"I have been shooting Glocks since 1990. The most reliable, repeatable triggers (Edited to add SAFE) triggers I have had and used came with the 5.5 TRS (OEM trigger return spring) with an OEM "minus" connector, a dab of grease/lub on the bearing surfaces and thousands of dry fires/live fires. Move away from this formula, particularly with non OEM parts or parts that get "polished" to the point that metal is removed at your own peril.
It is not a 1911 trigger and is never going to be. If that is driving your train then 1. get a 1911 or 2. consider the offerings of Apex for the M&P.
Be safe and well all."
I only have Gen 1-3 guns. I am told that some Gen4 and Gen5 guns are quite fine with completely stock set ups. See an armorer, get it back to stock. Dry fire the snot out of it, take a class and shoot it and I suspect that your trigger and your results will be just fine.
