Apex Tactical 100076 Duty/Carry Trigger Kit – .40 S&W for S&W M&P Pistol (Metal)

Sold by Tucson Arms – Licensed FFL Dealer, Tucson, Arizona – Ships to All 50 States

If you’re running a Smith & Wesson M&P in .40 S&W and you’ve been looking for a trigger that cleans up the factory mush without turning your duty gun into a race gun, this is it. The Apex Tactical Duty/Carry Kit (part number 100076) is built for the metal-frame M&P pistols—not the polymer-frame versions, not the Shield—the full-size and compact metal guns chambered in .40. Apex knows what they’re doing out of their shop in Prescott, Arizona, and we stock their stuff here at Tucson Arms because it works. Period.

This kit is designed to knock about two pounds off your pull weight compared to the factory trigger, depending on where your pistol’s tolerances land. Some M&Ps come out of the box at 6.5 pounds, some at 7.5—this kit brings it down into the 4.5 to 5.5 pound range. That’s the sweet spot for a service pistol: light enough that you’re not fighting the trigger on follow-up shots, heavy enough that you’re not going to ND when adrenaline hits. No “hair trigger” nonsense here. This is a working trigger.

What you get in the box: a fully machined 2-Dot sear, the Apex Ultimate Striker Block (USB), a striker block spring, a Talon tactical tool, a sear spring, a slave pin, and a trigger return spring. That’s everything you need to swap out the guts of your M&P’s fire control group. The 2-Dot sear is the heart of it—machined from billet steel, not MIM, with a smoother engagement surface that eliminates that gritty, stacking feel you get from the factory part. The shorter over-travel means you’re not waiting for the break to end, and the reset is more tactile. You’ll feel it click back into place without having to guess.

Let’s talk about that Ultimate Striker Block. Apex designed it to reduce striker drag on the primer, which keeps things consistent round after round. It also lightens the striker block spring pressure just enough to smooth out the take-up without compromising safety. The USB is a drop-in part, but Apex recommends—and we agree—that you have an armorer or a competent gunsmith install it into the slide. The striker block channel on M&Ps can be finicky, and a botched install can cause light primer strikes. If you’re local to Tucson, bring your slide by the shop and we’ll set it up right. If you’re ordering online, find a smith you trust. It’s worth the peace of mind.

This kit is specifically for the metal-frame M&P in .40 S&W. That includes the M&P9 M2.0 Metal, M&P9 Metal Competition, and the .40 versions of those models. If you’ve got a polymer M&P or a Shield, this isn’t the right kit—Apex makes separate kits for those. Check your frame material and caliber before you order. We’re happy to help if you’re not sure; just give us a call or send a message.

Installation isn’t impossible for a DIY guy with good tools and a steady hand, but it’s not a five-minute job either. You’ll need to detail strip the frame, remove the factory sear housing block, and swap out the sear, springs, and striker block. The Talon tool included in the kit helps with the trigger return spring—it’s a pain to get in without it. Take your time, follow Apex’s instructions (they’re available online), and test function with snap caps before you hit the range. If you’d rather not mess with it, we offer installation services here at Tucson Arms. Drop off your pistol, we’ll do the work, and you’ll pick it up ready to run.

Why buy from Tucson Arms? Because we’re a licensed FFL dealer right here in Tucson, Arizona—out of the heat and dust where people actually shoot year-round. We ship to all 50 states via FFL transfer.
