The Apex Tactical Action Enhancement Kit 100126 is a drop-in trigger upgrade designed to transform the factory trigger experience on your S&W M&P 2.0 pistol. If you carry or compete with an M&P 2.0 and want a smoother, more predictable press without the mushy factory feel, this kit addresses the most common complaint shooters have about the platform—a vague, inconsistent trigger break. Apex engineered this trigger to reduce pre-travel and over-travel by roughly 20%, giving you a crisper, more confidence-inspiring shot sequence while maintaining a safe 5- to 5.5-pound pull weight suitable for duty and carry use.

What sets this kit apart is the complete system approach. You're not just swapping a trigger shoe; you're getting a heavy-duty sear spring, a machined sear, a full duty/carry spring set, the Ultimate Striker Block Kit, and a trigger return spring with an installation slave pin. Apex designed these parts to work together, so you get a cohesive improvement rather than a band-aid fix. The trigger itself features a rounded face that sits naturally under your finger, and the center-mounted pivoting safety preserves the factory safety architecture—no surprises in manipulation or feel.

Drop-in installation is the promise, though Apex recommends having an armorer or gunsmith perform the work to ensure proper function and safety. This is the right call for a trigger system; it's not a sights-and-rails bolt-on job. Once installed, you'll notice the shorter reset immediately—it makes follow-up shots faster and more natural, whether you're at the range or training for defensive carry.

Frequently Asked Questions

Will this trigger kit work in my S&W M&P 9mm or .40 caliber?

No. The Apex Tactical Action Enhancement Kit 100126 is engineered specifically for the S&W M&P 2.0 in .45 ACP. It will not work in M&P 9mm, M&P .40, M&P Shield, or M&P .22 LR models. Apex makes separate trigger kits for other M&P platforms, so check compatibility before ordering.

Can I install this trigger myself, or do I need a gunsmith?

While the kit is designed as a drop-in system that typically doesn't require gunsmithing, Apex recommends having an armorer or gunsmith perform the installation. Professional installation ensures the kit functions safely and reliably, which is especially important with a trigger system.

What does the kit include?

The Action Enhancement Kit includes the trigger itself, a heavy-duty sear spring, a machined sear, a complete duty/carry spring set, the Ultimate Striker Block Kit, a trigger return spring, and an installation slave pin to assist with disassembly and reassembly during install.

Is this trigger safe for carry and duty use?

Yes. The trigger pull weight is maintained at 5 to 5.5 pounds, which meets the safety threshold for defensive carry and duty applications. The center-mounted pivoting safety also preserves the factory safety function and feel.
