Description
The Apex Action Enhancement Trigger and Duty/Carry Kit brings a noticeable improvement to the M&P Shield M2.0 without compromising the pistol's carry-friendly design. This kit pairs a solid aluminum trigger body with a complete set of refined internal components, including a machined sear, striker block, and optimized springs. The result is a significantly better trigger feel that makes daily carry and range work more enjoyable.
What Makes the Apex Trigger Different
The main upgrade here is swapping out the factory hinged trigger for a smooth aluminum trigger body that reduces travel distances by about 20%. Instead of fighting through excess pre-travel and over-travel, you get a more direct trigger action. The center-mounted pivoting safety stays put, so you're not making your Shield less safe, just better feeling. The pull weight typically drops 1-2 pounds depending on your gun's individual tolerances, and you get a more noticeable reset when you let off each shot.
Installation and Components
This is advertised as a drop-in upgrade, though most people have a gunsmith or armorer handle the installation since it requires disassembly of the action. The kit includes the aluminum trigger itself, a fully machined 1-dot sear, the Ultimate Striker Block, striker block spring, sear spring, trigger return spring, a slave pin for assembly, and an installation tool to help things go smoothly. All the parts work together to deliver smooth uptake and a crisp break.
Real-World Performance
Owners report that this trigger transforms the Shield into a genuinely shootable carry gun. The reduced travel and lighter pull make it easier to shoot accurately, especially at distance. The reset is much more tactile than factory, which helps with faster follow-up shots. While the Shield 2.0 already came with improvements over the original Shield, this kit takes it to another level. It's not a target-grade trigger, but it's a significant step up for a defensive pistol.

Frequently Asked Questions
Can I install this trigger myself or do I need a gunsmith?
While the kit is technically a drop-in design, most people have a qualified gunsmith or armorer handle installation because it requires significant disassembly of your Shield's action. The trigger bar pin installation in particular can be tricky if you don't have experience. A professional install typically runs $45-75 and is worth it to ensure everything works correctly.
Will this trigger work in both 9mm and .40 S&W Shield 2.0 models?
Yes, this kit is compatible with Smith & Wesson M&P Shield 2.0 pistols in both 9mm and .40 S&W. It does not work in the original Shield, Shield .45, Shield EZ, or any pistol chambered in 30 Super Carry.
Does this kit change the factory safety mechanism?
No. The center-mounted pivoting safety remains unchanged and maintains all factory safety values. The new aluminum trigger body just actuates it differently than the original hinged trigger, but the function and protection stay the same.
What's the Ultimate Striker Block and why is it included?
The Ultimate Striker Block is a component that installs into your slide and works with the duty/carry kit to improve overall trigger performance and reliability. Apex recommends having a gunsmith install it into the slide, which is why most people handle the full installation professionally.
