What You’re Getting

This is the full Apex Tactical 100161 kit – two boxes in one. You get the Apex Duty/Carry Kit and the Apex Action Enhancement Trigger, both made specifically for the S&W M&P Shield 45 and Shield 45 M2.0. Apex builds these in the USA. We stock them here at Tucson Arms because they work, and they keep working.

The Trigger

That factory hinged trigger on your Shield 45? This kit takes it out and replaces it with a solid aluminum trigger body. Machined, not cast. It’s got a smooth face with a center-mounted pivoting safety that keeps all the factory safety values intact – no bypassing anything. The geometry alone cuts pre-travel and over-travel by about 20%. You feel it on the first pull. Shorter take-up, less slop after the break, and a reset that clicks back loud enough to track without looking.

The Duty/Carry Kit

This is the part that changes the feel of the whole gun. The Duty/Carry kit reworks the sear, striker block, and springs to give you a consistent pull right around 5.0 to 5.5 pounds. Not a competition trigger – this is for a gun you carry or keep in a nightstand. It’s smooth, it’s predictable, and it doesn’t turn your Shield into a hair trigger. You get a shorter over-travel stop and a more detectable reset. That means faster follow-up shots without guessing where the wall is.

Installation Notes

If you’ve done an Apex kit before, you can handle this one. If you haven’t, it’s straightforward but take your time. We recommend a roll pin punch set and a small hammer. Apex includes good instructions. No gunsmithing required, but a steady hand helps. If you’re in Tucson, stop by the shop and we’ll walk you through it. Online orders – the kit ships with all the parts you need.

Why This Kit

The Shield 45 is a snappy gun. The factory trigger doesn’t help. Apex fixes that without making the gun unsafe. You keep the striker block, you keep the safety, you keep the gun reliable. What you lose is the mush, the creep, and the vague reset. The trigger breaks clean, resets short, and stays at a weight that won’t make you flinch. It’s the same kit we run in our personal Shields here at Tucson Arms. It’s not fancy – it’s just better.

One More Thing

We don’t sell junk. We test what we carry. This Apex kit has been in our rental guns and personal carry pieces for years. It holds up.

Just a solid part from a solid company, sold by people who actually shoot.
