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 hitting your marks fast, this kit from Apex Tactical is the real deal. We’ve seen a lot of trigger jobs come through the shop, but Apex’s Competition Action Enhancement Kit is the one that keeps showing up in match bags and range bags alike. It’s not flashy—it’s functional. And that’s exactly what you want when the timer starts.

This is a drop-in metal kit that takes the factory trigger pull—usually sitting around 7.0 to 8.0 pounds—and drops it by about four pounds. That’s a noticeable difference. The break gets cleaner, the reset gets snappier, and you’re not fighting a heavy pull when you’re trying to stay on target. Apex uses shot-peened striker and trigger return springs here, which means they hold up better over the long haul. No sagging, no surprises after a few thousand rounds.

Installation is straightforward enough for someone who’s comfortable detail-stripping an M&P, but we always recommend having an armorer or a gunsmith handle it if you’re not 100% sure. One wrong step and you’re chasing parts across the bench. That said, the kit is engineered to drop in without extra fitting in most cases. It pairs best with M&P pistols that already have an Apex Polymer or Aluminum Action Enhancement Trigger installed—if you’re starting from a stock gun, you’ll want to pick up one of those triggers first.

This isn’t a gimmick. It’s a practical upgrade for competitors and experienced shooters who need consistent, repeatable trigger behavior round after round. No mush, no creep, just a clean break that lets you focus on the front sight. Whether you’re shooting USPSA, steel challenge, or just running drills on a Saturday morning, this kit will tighten up your splits and make your .40 feel like a whole different gun.

We’re Guns Warehouse, and we ship nationwide to all 50 states through your local FFL. If you’ve got a license, we’ll get this out the door fast. No fuss, no nonsense—just good gear from a shop that knows what works.
