Apex Tactical Competition Action Enhancement Kit .40 S&W

Folks, if you’re running a Smith & Wesson M&P in .40 S&W and you’re serious about shaving time off your splits at the range or in competition, listen up. This here is the Apex Tactical Competition Action Enhancement Kit. Apex Tactical out of Arizona builds these kits, and they know what they’re doing. We’re a licensed FFL dealer right here on the Texas border—Bordertown Guns—and we ship these to every state in the union, no exceptions.

This drop-in metal kit is built for action shooters who need a clean, consistent trigger break without the heavy factory pull. Stock M&P triggers in .40 S&W usually sit around 7 to 8 pounds. This kit drops that pull weight by about 4 pounds, getting you down into a much more manageable range for fast, accurate shooting. It uses a shot-peened striker spring and a shot-peened trigger return spring—hardened steel that holds up better over thousands of rounds compared to the factory springs. That means less wear, fewer surprises.

Now, Apex engineered this as a drop-in kit, meaning for most M&P models you won’t need to file or fit anything. But I’ll be straight with you: if you’re not comfortable detail-stripping your pistol’s frame and working with sear engagement, have a gunsmith or a qualified armorer handle the install. It’s straightforward if you know your way around a pistol, but we’d rather see you get it done right than force it.

One thing to note—this kit is designed to work with M&P pistols that already have an Apex Polymer or Aluminum Action Enhancement Trigger installed. If you haven’t swapped your trigger shoe yet, you’ll need to pick one of those up first. This is the internal kit that does the heavy lifting on the pull weight and consistency.

At Bordertown Guns, we handle our business the same way we handle our firearms—no nonsense, no fluff. This Apex kit is a solid upgrade for competitors who want a repeatable, reliable trigger without turning their pistol into a science project. It’s built to last, it’s made in the USA, and it ships from our shop to your FFL dealer wherever you are. If you’ve got questions, give us a call or stop by. We’ll set you straight.
