Loving this M&P9. first handgun I've owned in a long time that has been perfect out of the box. Seeing all these threads about trigger jobs has got me thinking I may benefit from it. My M&P9 is the standard one, not the PRO version. I am not one to "tinker" with stuff so I will admit to being a bit intimidated by the thought of it. APEX seems to be the trigger of choice around here. Specifically, which trigger is the one I need to be looking at and on a 1-10 (10 being the HARDEST THING YOU'VE EVER ATTEMTED) scale how difficult is it to complete without completely screwing something up? I almost hate to even mess with the M&P, but the trigger could use some work.
