About this product
Apex Tactical Competition Action Enhancement Kit – .40 S&W
If you’re running a Smith & Wesson M&P in .40 S&W and you’re serious about tightening up your splits at the range or in a match, this kit from Apex Tactical is worth a hard look. We stock these here at Iowa Gun Shop in Des Moines because they deliver exactly what they promise: a cleaner, lighter trigger pull without turning your pistol into a project gun.
Apex Tactical built this Competition Action Enhancement Kit as a drop-in metal setup. It knocks about four pounds off the factory trigger pull—assuming you’re starting around 7 to 8 pounds, which is typical for these pistols. That gets you down into the 3–4 pound neighborhood, which is where a lot of competitive shooters want to be. The kit uses shot-peened striker and trigger return springs, so they hold up better over time than the stock parts. You won’t be swapping them out every season.
Installation is straightforward for someone who’s done this before, but we’ll be honest: if you haven’t worked on an M&P trigger, get a gunsmith or armorer to handle it. It’s not that it’s hard, but a few minutes with a pro saves you headaches and keeps everything running right. The kit is designed to fit M&P pistols that already have an Apex Polymer or Aluminum Action Enhancement Trigger installed. If yours is stock, you’ll want to pick up one of those triggers first.
This isn’t a magic box that rewrites your pistol’s DNA—it’s a practical, engineered upgrade that makes a real difference in how the gun feels and performs. The trigger break is more predictable, the reset is positive, and the overall consistency goes up. For competitors and experienced shooters who rely on repeatable performance, that’s what counts.
