The Apex Tactical 100056 Action Enhancement Trigger & Duty/Carry Kit upgrades your Smith & Wesson M&P Shield with a refined, combat-ready trigger that transforms how the pistol breaks. Designed specifically for Shield owners who carry daily or train seriously, this kit pairs a red anodized aluminum trigger body with a complete duty/carry enhancement system. The core upgrade cuts trigger pre-travel and over-travel by roughly 20%, giving you a noticeably shorter, more predictable press—critical when reliability and consistency matter most. The kit delivers a lighter trigger pull (approximately 1–2 lbs lighter than factory, accounting for normal tolerance variation) and a more definable reset, so follow-up shots feel intuitive and fast.

The solid red trigger body replaces the factory hinged design with a smooth face and a center-mounted pivoting safety that maintains factory safety geometry. That safety bar won't disengage unless your finger is directly on the trigger face, preserving the safety margin that duty and carry demand. Apex engineered this as a drop-in kit, meaning no extensive gunsmithing should be required to install it—though pairing it with professional gunsmith installation of the Ultimate Striker Block into your slide is strongly recommended for optimal performance and peace of mind.

If you already own an M&P Shield equipped with an Apex Duty/Carry Kit, the trigger itself can be purchased separately for upgrade or replacement. Compatibility is straightforward: this kit works with all S&W M&P Shield models in 9mm and .40 caliber. Note that it does not function in the Shield .45 platform.

Frequently Asked Questions

Does the Apex Tactical 100056 kit work with my S&W M&P Shield?

Yes, it's compatible with all Smith & Wesson M&P Shield models chambered in 9mm and .40 caliber. It does not work with the Shield in .45 ACP.

Can I install this trigger kit myself?

Apex designed the kit as a drop-in, so extensive gunsmithing shouldn't be necessary. However, professional gunsmith installation of the Ultimate Striker Block into your slide is strongly recommended for optimal function and reliability.

How much lighter is the trigger pull compared to factory?

The kit provides approximately 1–2 lbs lighter trigger pull than the factory trigger, though the exact reduction depends on variations in factory tolerances of your specific pistol.

If I already have an Apex Duty/Carry Kit on my Shield, can I buy just the trigger separately?

Yes. The Apex Shield Action Enhancement Trigger is sold separately for owners who want to upgrade or replace the trigger on a Shield that is already equipped with the Duty/Carry Kit.
