Apex Tactical 100179 Action Enhancement Duty/Carry Kit - Drop-in Trigger for S&W M&P 2.0, 5-5.50 lbs Draw Weight, Black Finish

The Apex Tactical 100179 Action Enhancement Duty/Carry Kit is a drop-in trigger upgrade designed specifically for the S&W M&P 2.0 platform. If your factory M&P trigger feels heavy, mushy, or inconsistent, this purpose-built kit transforms the shooter experience with a noticeably cleaner break and a 5–5.5 lb pull weight that's ideal for duty and carry applications. The aluminum trigger shoe is machined with a rounded profile that seats your finger naturally, while the entire assembly is engineered to reduce pre- and over-travel—meaning less creep before the shot breaks and less mushy reset afterward.

This isn't a bare trigger; Apex bundles everything needed for a complete trigger job: the aluminum trigger itself, a heavy-duty sear spring, a machined sear, the duty/carry spring set, the Ultimate Striker Block Kit, and a slave pin for trigger return spring installation. The design maintains the factory safety architecture, so you're not compromising the safe, predictable operation that duty guns demand. Drop-in installation is the goal, though gunsmith or armorer assembly is recommended if you're not comfortable working on striker-fired triggers.

Apex built this kit for the .45 ACP and M2.0 versions of the M&P—it is not compatible with M&P 9mm/.40, M&P Shield, or .22 LR models. Confirm your exact M&P variant before ordering. For shooters running an M&P 2.0 who want a trigger that feels refined, breaks cleanly, and shoots true without losing safety margins, the 100179 Action Enhancement Kit is a proven upgrade that pays for itself in tighter groups and faster, more confident splits.
