Apex Tactical 100161 Action Enhancement Trigger & Duty/Carry Kit – S&W M&P Shield 45

Let’s talk about your Shield 45. If you’ve been running that factory hinged trigger and thinking, “There’s got to be something better,” you’re right. This is the Apex Tactical 100161 kit, and it’s the real deal. Apex has been making triggers for Smith & Wesson M&P pistols long enough that they’ve got it dialed. This kit combines their Duty/Carry kit and their Action Enhancement Trigger into one drop-in package that’s built for the Shield 45 and Shield 45 M2.0. No guesswork, no gunsmithing degree required.

First thing you’ll notice: that factory hinged trigger is gone. Replaced with a solid aluminum trigger body. Smooth face, center-mounted pivoting safety that keeps all the factory safety specs intact. Apex didn’t cut corners on safety—they just made the trigger better. Pre-travel and over-travel get cut down by about 20%. That’s not a gimmick, that’s measurable. You pull the trigger, it moves less, it stops sooner, and you stay on target.

The Duty/Carry side of this kit is where it really shines for everyday use. Apex tuned it to a pull weight right around 5.0 to 5.5 pounds. That’s not a hair trigger. That’s a consistent, repeatable pull that works for concealed carry or duty use. No mush, no stacking. Just a clean break and a short, positive reset you can feel and hear. The over-travel is shorter than stock, and the reset is more detectable—so when you’re shooting fast, you know exactly when that trigger is ready to go again.

This kit is drop-in. You don’t need to file, fit, or swear at it. Take your Shield 45 apart, swap the parts, put it back together. If you’ve field-stripped your pistol, you can do this. Apex includes everything you need in the box. No chasing extra springs or pins.

Now, a bit of real talk from Billings. We’ve got weather here that changes faster than a politician’s promise. Cold mornings, hot afternoons, wind that’ll push your hat off. Your carry gun needs to work every time. This Apex kit is built for that. The aluminum trigger won’t warp or flex. The internal geometry is machined to tight tolerances. It’s not a race gun part—it’s a carry part. That’s why we stock it at Firearms Montana.

We’re a licensed FFL dealer right here in Billings, and we ship to all 50 states. If you’re in Montana, stop by the shop. If you’re in Florida or Alaska or anywhere in between, we can get this out to your local FFL. Just make sure you know your state and local laws—we’ll handle the rest.

Price is $165.00. That’s a fair price for a trigger kit that turns a good pistol into a great one. No hype, no marketing fluff. Just a better trigger from a company that’s earned its reputation. Apex Tactical makes this, we stock it, and we stand behind it.

If you’ve got questions, give us a call or swing by. We’ll talk triggers, holsters, or just the weather. You don’t have to be a gunsmith to appreciate a good trigger—you just have to shoot one.
