If I’m being honest, one of the first things I did was remove the factory PC trigger and replace it with an Apex Duty Carry trigger kit with the Poly/Curved trigger. While the pull and the break on the factory PC trigger felt pretty good, I’ve always disliked the hinged shoe on the M&Ps. The curved factory shoe just always felt kinda wonky to me and just never felt good to my trigger finger.
The Apex Aluminum/Curved FSS Kit is really slick and can be lightened up from where mine is at 4.5lb to significantly lighter if you wish. I’m planning on keeping the Apex FSS installed in my duty gun based off of how I shot with it over the past two days.
I believe CHPWS has an ACRO plate for the new 2020 CORE/“Optics Ready” footprint but it’s not available yet.
Word is that Aimpoint is releasing a updated ACRO with significantly improved battery life using a 2032 battery very soon.
