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 shaving time off your splits, this Apex Tactical Competition Action Enhancement Kit is exactly what you need. Straight out of Prescott, Arizona, Apex Tactical knows what it takes to make a production gun feel like a custom rig. This drop-in metal kit pulls about 4 pounds off that factory trigger—most stock M&Ps come in around 7 to 8 pounds, so you’re looking at a crisp 3-4 pound pull after install. That’s a whole lot of slop and grit gone, just clean breaks.

The kit is built around shot-peened striker and trigger return springs. That’s not just fancy talk—it means they’ve been hardened and smoothed to last longer than the factory springs, even under heavy use. The whole thing is metal construction, no plastic parts to wear out or flex. It’s designed to drop in without a bunch of filing or fitting, but we’ll be straight with you: we recommend having a gunsmith or certified armorer handle the install. It’s not that it’s hard, but a trigger job is one of those things you want done right the first time. If you’re local to Louisville, stop by Kentucky Gun Shop and we can point you to a few smiths we trust. If you’re ordering from out of state, we ship nationwide via FFL—just make sure your receiving dealer is on board.

One thing to keep in mind: this kit works with M&P pistols that already have an Apex Polymer or Aluminum Action Enhancement Trigger installed. If you haven’t upgraded the trigger itself yet, you’ll want to pick one up first. The kit is compatible with all M&P models chambered in .40 S&W, so it covers the full-size, compact, and even the Shield if you’re running that caliber.

This isn’t for the casual plinker. It’s for the competitor who wants repeatable, predictable trigger pulls round after round. The springs are engineered for extended service life, and the whole package is built to hold up to the abuse of match schedules and practice sessions. At $115.50, it’s a solid investment in consistency. Whether you’re at the range in Jeffersontown or shooting a match out in Shepherdsville, this kit will tighten up your groups and shave time off your transitions.

Order it from Kentucky Gun Shop and we’ll get it out the door fast. If you’re in Louisville, come see us in person. If you’re anywhere else in the country, we’ll ship it to your FFL—all 50 states, no exceptions. Apex Tactical makes the parts; we make sure you get ’em.
