Description
The Apex Action Enhancement trigger kit takes one of the most commonly upgraded parts on an M&P M2.0 and delivers real improvements where it matters. You get a solid aluminum trigger body that replaces the factory hinged design, paired with a center-mounted pivoting safety that keeps everything you're familiar with intact. The rounded trigger face is shaped for comfort and the set screw lets you dial in over-travel to your preference.
What You're Getting with the Aluminum Design
This kit includes way more than just a trigger. You'll get the aluminum trigger itself, a fully machined sear, heavy duty sear spring, duty-carry trigger return spring, the Ultimate Striker Block kit with the Talon Tactical tool, and a slave pin to help during installation. That comprehensive setup means you're upgrading multiple components that work together to improve the whole action. The aluminum construction is machined from 6061 T6 billet and gets a Type 2 hardcoat anodize finish, so it'll hold up to regular use without wearing down.
Performance Gains That Show Up at the Range
The numbers tell the story. You'll see pre-travel and over-travel reduced by approximately 30%, with a shortened trigger reset that makes follow-up shots snappier. The trigger pull weight drops by roughly 1 lb from factory, landing you in that sweet 5.0 to 5.5 lb range that works for duty or carry applications without feeling like a match trigger. This is a drop-in designed kit, though Apex recommends having an armorer or gunsmith handle the install if you're not experienced with pistol work. The design maintains factory safety values while giving you a noticeably improved trigger experience.
What to Know Before You Buy
This kit is engineered specifically for the M&P M2.0 in 9mm, .40 S&W, and .45 ACP, including compact variants. It also works with the original M&P 45. It will not function in the original M&P 9mm or .40 models, M&P Shield guns, M2.0 Metal Series models, or 10mm variants. Make sure you verify your specific platform before ordering.

Frequently Asked Questions
Will this trigger kit work in my M&P 2.0 compact?
Yes, the Apex aluminum trigger kit works in all M&P M2.0 variants, including full-size and compact models in 9mm, .40 S&W, and .45 ACP. It's also compatible with the original M&P 45. Just make sure you don't have a Shield model, Metal Series M2.0, or 10mm version, as those aren't compatible.
Do I need a gunsmith to install this kit?
The kit is designed as a drop-in replacement, so it's technically installable yourself if you have some pistol armorer experience. That said, Apex recommends having a qualified armorer or gunsmith do the installation to ensure everything functions properly. If you're not confident with the install, it's worth the money to have it done right.
How much lighter will the trigger feel compared to factory?
The pull weight drops by approximately 1 lb from the stock M&P M2.0, landing you in that 5.0 to 5.5 lb range. Beyond just the weight, you'll notice the pre-travel and over-travel are cut by about 30%, which makes the trigger feel shorter and snappier even if the weight difference seems modest on paper.
What makes the aluminum trigger different from the polymer version?
The aluminum version is machined from 6061 T6 billet and gets a hardcoat anodize finish, making it more durable and resistant to wear over thousands of rounds. It delivers the same improved pull weight and reduced travel as the polymer kit, but the aluminum construction is more robust for high-use applications or if you just prefer the durability.
