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

Howdy from down here on the Texas border. We see a lot of M&P pistols come through Bordertown Guns, and if you’re running a .357 Sig, you already know it’s a flat-shooting round that demands a trigger you can trust. That’s where this Apex Tactical kit earns its keep. It’s not about turning your duty gun into a race gun – it’s about making a good trigger better without crossing the line into light-strike territory.

Apex designed this Duty/Carry kit to drop the pull weight to a consistent 5.0 to 5.5 pounds, shave off the over-travel, and tighten up the reset. The sear and striker block are fully machined from metal – no MIM parts here, just solid pieces that lock up tight and break clean. The spring set is tuned for service loads, so you’re not chasing reliability issues on a hot day down by the river. Every part in the bag is meant to work together, not just a handful of random springs tossed in a box.

Installation is drop-in, but we’ll be straight with you: if you haven’t torn down an M&P before, take it to a gunsmith. Apex themselves recommend a pro install, and we do too. One wrong step on that striker block and you’re looking at a dead trigger. That said, if you’ve got the know-how and the right tools, it’s a straightforward swap. The kit includes the sear, the Duty/Carry spring set, the Ultimate Striker Block Kit, and a slave pin to hold it all together while you work.

What you get on the range is a trigger that breaks like glass, resets short and positive, and doesn’t leave you hunting for the wall between shots. It’s built for the guy carrying a .357 Sig on the border or the officer running it on the job. The pull weight stays service-appropriate, so you won’t get sideways looks from your department armorer.

This kit fits S&W M&P pistols in 9mm, .357 Sig, and .40 S&W – but we’re listing it here for the .357 Sig crowd because that’s what you asked for. If you’re shooting something else, we’ve got those too. Call us or stop in.
