Apex Tactical Duty/Carry Action Enhancement Kit 357 Sig

Apex Tactical Duty/Carry Action Enhancement Kit – .357 Sig

If you’re running an S&W M&P in .357 Sig, you know that round hits hard and fast. But the factory trigger? It leaves a little to be desired. That’s where this kit from Apex Tactical comes in. They’ve been building dependable trigger upgrades for years, and this Duty/Carry Action Enhancement Kit is built for folks who carry their M&P daily or run it on the job. No fluff, no nonsense—just a cleaner, more predictable trigger pull that keeps you on target.

This kit is engineered to give you a consistent 5.0 to 5.5 lb trigger pull. That’s right in the sweet spot for duty or concealed carry—heavy enough to be safe, light enough to shoot straight. You’ll notice the over-travel is cut way down, and the reset is shorter and snappier. Follow-up shots feel natural, not like you’re fighting the trigger to get back on target.

Everything in the box is fully machined metal—no plastic, no shortcuts. You get a precision sear, a duty/carry spring set, the Ultimate Striker Block Kit, and a slave pin to make assembly easier. It’s designed as a drop-in kit, but if you’re not comfortable tearing down your M&P’s fire control group, we recommend having a qualified armorer or gunsmith handle the install. Apex builds these parts to work together as a system, so you get repeatable performance shot after shot.

This kit fits S&W M&P pistols in 9mm, .357 Sig, and .40 S&W—so if you’ve got more than one caliber in the safe, you’re covered. But we’re highlighting the .357 Sig here because it’s a favorite for folks who want barrier penetration and flat-shooting ballistics. Pair that with a refined trigger, and you’ve got a serious setup.

At Guns Warehouse, we ship nationwide to any licensed FFL dealer. Whether you’re in the high desert, the piney woods, or somewhere in between, we’ll get this kit out the door and on its way to your local shop. No state is too far—Alaska to Florida, we’ve got you covered.

Bottom line: if you want a trigger that feels like it should’ve come from the factory, but with a bit more refinement for real-world carry, this Apex Tactical kit is the way to go. Reliable, repeatable, and built for the long haul.
