Apex Tactical Duty/Carry Action Enhancement Kit for S&W M&P pistols. Designed to deliver a consistent 5.0–5.5 lb trigger pull with shorter over-travel and a shortened reset. Drop-in design; armorer or gunsmith installation recommended.
Ships to all 50 states. Available nationwide.
If you’re carrying a S&W M&P in .357 Sig — and a lot of guys out here in Billings run that round for its flat-shooting, barrier-blind performance — you know the factory trigger leaves room for improvement. It’ll get the job done, but it won’t help you when split times matter. That’s where Apex Tactical comes in. They’re the go-to for M&P triggers, and this Duty/Carry Action Enhancement Kit is built for exactly what it says: duty and carry. No race gun nonsense, no featherweight pulls that’ll get you sued.
This kit is engineered to give you a clean, repeatable 5.0 to 5.5 lb pull. That’s service weight — safe for holster work, safe for cold hands on a January morning outside of town. What you get is a fully machined sear, a duty/carry spring set, the Ultimate Striker Block Kit, and a slave pin. All metal components, all precision-cut. The goal here is shorter over-travel and a shorter, more positive reset. You’ll feel it on the second shot. And the third.
Apex says it’s a drop-in kit, and technically it is. But if you’re not comfortable detail-stripping your M&P frame, bring it to a gunsmith. We see guys who rush this and end up with light strikes or a gritty pull that defeats the purpose. Have a professional install it, or if you know your way around the platform, take your time and follow the instructions. The result is a trigger that breaks clean, resets short, and doesn’t change the fundamental safety of the gun.
This kit works with 9mm, .357 Sig, and .40 S&W M&Ps. So if you’ve got a .357 Sig barrel in your .40 — and a lot of Montana shooters do — you’re covered. We stock these at Firearms Montana here in Billings, and we ship nationwide to your FFL. Just give us your dealer’s info and we handle the rest. No fuss, no nonsense. Just a better trigger for a gun you already trust.
