Apex Tactical Duty/Carry Action Enhancement Kit 357 Sig

Apex Tactical Duty/Carry Action Enhancement Kit – .357 Sig (Fits 9mm & .40 S&W Too)

Here in Des Moines, we know a thing or two about getting the job done right. Whether you’re carrying concealed on a cold morning in the metro or running drills out past Ankeny, you want gear that’s dependable. That’s why we stock the Apex Tactical Duty/Carry Action Enhancement Kit for S&W M&P pistols. This isn’t a race gun part—it’s built for the real world, where consistency and control matter more than a hair trigger.

Apex Tactical, the manufacturer, designed this drop-in kit to give you a clean, repeatable 5.0 to 5.5 lb trigger pull—right where a service pistol should be. You get a shorter, more positive reset and reduced over-travel, which means your follow-up shots stay tight without losing the safety margins you need for duty or carry. The kit includes a fully machined sear, a duty/carry spring set, an Ultimate Striker Block Kit, and a slave pin. All components are precision-machined metal, meant to work together for reliable performance round after round.

Compatibility: This kit fits S&W M&P pistols in .357 Sig, 9mm, and .40 S&W. If you’re running a .357 Sig—like a few of our customers who swear by it for that extra punch—you’re covered. Installation is straightforward as a drop-in, but we always recommend having a qualified armorer or gunsmith do the work to make sure everything’s tuned right. You can bring it by our shop in Des Moines, or we can ship it to your FFL dealer anywhere in the country.
