Apex Tactical Duty/Carry Action Enhancement Kit 357 Sig

If you’re running a Smith & Wesson M&P in .357 Sig, you already know the round packs a punch. What you might not love is the factory trigger. That’s where this Apex Tactical Duty/Carry Action Enhancement Kit comes in. Apex Tactical is the name in M&P trigger upgrades—they’ve been at it longer than most, and their stuff just plain works. This kit is made specifically for the .357 Sig, along with 9mm and .40 S&W, so you’re not guessing on fit.

We’re talking about a drop-in kit that gets your pull weight to a consistent 5.0 to 5.5 pounds. That’s right in the sweet spot for a duty or carry gun—heavy enough to be safe, light enough to shoot straight. The kit includes a fully machined sear, a duty/carry spring set, an ultimate striker block kit, and a slave pin. All metal parts, no plastic junk. The goal here is simple: shorter over-travel and a shorter, more positive reset. You’ll feel the difference on the second shot, and the third, and the fourth.

Now, Apex says professional installation is recommended, and we’ll echo that. If you’ve got a gunsmith you trust, have them put it in. If you’re handy with a punch and a vise, you can do it yourself, but take your time. Once it’s in, you’ll get a clean, crisp break without the grit and mush you get from the factory setup. It’s not a race gun trigger—it’s a carry trigger. It’s meant to be reliable, repeatable, and safe when it counts.

Here in Louisville, we know a thing or two about shooting. Whether you’re at the range out in Jeffersontown or carrying down I-65, you want gear that doesn’t quit. This Apex kit delivers. And since Kentucky Gun Shop is a licensed FFL dealer, we can ship this out to you no matter where you are—all 50 states, no problem. Just make sure your receiving FFL is lined up, and we’ll take care of the rest.

Price is $110. That’s a fair shake for what you’re getting: machined parts, proven design, and a trigger that’ll make your M&P feel like a whole different gun. Give us a call or order online. We’ll get it headed your way.
