Apex Tactical Duty/Carry Action Enhancement Kit – .357 Sig
Alright, let’s talk triggers. If you’re running a S&W M&P in .357 Sig (or 9mm or .40 S&W) and you want a cleaner pull without going too light for carry or duty, Apex Tactical has the answer. This is the Duty/Carry Action Enhancement Kit, and it’s built to give you a smooth, consistent 5.0 to 5.5 lb trigger pull—right in that sweet spot for reliable self-defense or on-duty use.
What’s in the box? You get a fully machined sear, a duty/carry spring set, the Ultimate Striker Block Kit, and a slave pin. All metal components, all drop-in ready. That said, we recommend having a qualified armorer or gunsmith handle the install—just to make sure everything’s dialed in. It’s not rocket science, but a pro touch never hurts.
The real payoff here is in the feel. The kit reduces over-travel and shortens the reset noticeably, so you’re not fighting a spongy trigger or waiting for the reset to catch up. Follow-up shots get quicker, and the whole action feels more precise without compromising reliability. Apex designed these parts to work together as a system, not just a pile of pieces. You get repeatable, consistent performance every time.
This isn’t a competition trigger—it’s a duty/carry kit. It keeps the pull weight where it needs to be for safety and legal standards, but cleans up the mush and grit factory triggers can have. If you’ve been putting up with a stock M&P trigger, this is the upgrade that makes you wonder why you waited.
