If you're running a Smith & Wesson M&P in .40 S&W for competition or just want a cleaner, lighter trigger without sending your pistol off to a smith for a week, this Apex Tactical Competition Action Enhancement Kit is the move. Apex Tactical has been the go-to for M&P trigger work for years, and this kit is purpose-built for shooters who want a serious reduction in pull weight without messing with the gun's reliability.

Out of the box, most .40 M&Ps roll out with a trigger pull somewhere between 7 and 8 pounds. This drop-in metal kit shaves off about 4 pounds from that, putting you in a much more manageable range for fast, accurate splits on the clock. It's not a gimmick—it's engineered. The kit includes shot-peened striker and trigger return springs that hold up better over the long haul than factory parts. That shot-peening process reduces metal fatigue, so you're not swapping springs every other season.

That said, if you're already running an Apex Polymer or Aluminum Action Enhancement Trigger, this kit drops right in with no extra fitting.

This kit is built for the .40 S&W specifically, so don't try to shoehorn it into a 9mm or .45—it's not the same. Apex knows the .40 has its own recoil impulse and slide dynamics, and they've tuned the springs and sear geometry accordingly. You get a consistent, repeatable trigger break that doesn't wander on you in the middle of a stage.
