Description
The factory trigger on an original Smith & Wesson M&P has never been the pistol's strong suit. That hinged safety blade and the long, spongy travel leave a lot on the table. This Apex Tactical kit fixes both problems by pairing the Action Enhancement polymer trigger with the full Duty/Carry Action Enhancement Kit, giving your M&P the trigger it should have shipped with from the start.
The trigger itself replaces the factory hinged unit with a solid-body polymer trigger that uses a center-mounted pivoting safety instead of the blade. The rounded face gives your finger a smooth, comfortable surface, and on its own the trigger trims pre-travel and over-travel by roughly 20 percent. Add the internal components from the Duty/Carry kit and you get the full package: a fully machined sear, a heavy-duty sear spring, the Duty/Carry spring set, and the Ultimate Striker Block Kit with a Talon Tactical tool for install.
What the Apex Action Enhancement Kit Does to Your M&P
Working together, these parts deliver a smooth, consistent trigger pull in the 5.0 to 5.5 lb range with shorter over-travel and a noticeably crisper, shorter reset. That pull weight is intentional. Apex tuned this one to stay in a sensible range for a carry or duty gun rather than dropping it into competition-light territory, so you get a better feel without going too light for serious use.
Fitment and Install Notes for This Apex Trigger Kit
This kit is built specifically for the original centerfire M&P in 9mm and .40 S&W. It does not fit the M&P 2.0, any Shield variant, the M&P 45, or the .22 models, so double-check your pistol before ordering. Everything is designed to drop in without cutting or fitting, though Apex recommends an armorer or gunsmith handle the install if you're not comfortable working inside your slide and frame. One thing worth knowing up front: this setup runs on the larger 1/8 inch sear plunger and spring, so if your older M&P still has the 1/16 inch setup, plan on updating the sear housing block first.

Frequently Asked Questions
Will this Apex trigger kit fit my M&P 2.0 or Shield?
No. This kit (part 100026) is made for the original centerfire M&P in 9mm and .40 S&W only. It does not work in the M&P 2.0, any Shield model, the M&P 45, or the .22 caliber M&P. Apex makes separate kits for those platforms, so check your exact model before you buy.
How light does the trigger get with this kit?
It settles into a smooth, consistent pull in the 5.0 to 5.5 lb range. That's intentional since this is the Duty/Carry setup, tuned to keep a sensible weight for a carry or duty gun rather than a light competition pull. You still get a much cleaner break, less travel, and a shorter reset than the factory trigger.
Is this really a drop-in install?
Yes, the components are designed to drop in without any cutting or fitting, and the kit includes the Talon Tactical tool to help. That said, you're working inside the fire control group, so if you're not comfortable detail-stripping your M&P, having an armorer or gunsmith do the install is a smart call.
Do I need anything else to run this kit?
This setup requires the larger 1/8 inch sear plunger and spring, which the kit provides. If you have an older M&P still running the 1/16 inch sear plunger and spring, you'll want to update to a newer sear housing block before installing. Newer M&P pistols already use the 1/8 inch setup, so most guns are good to go.
