Apex Tactical 100161 Action Enhancement Trigger & Duty/Carry Kit – S&W M&P Shield 45
Straight from the Apex Tactical bench to your holster – a drop-in trigger upgrade that actually works.
Here in Louisville, we know a thing or two about carrying a reliable sidearm. Whether you’re heading out on Bardstown Road or hitting the range out in Jeffersontown, your M&P Shield 45 needs to run clean and predictable. That’s where this Apex Tactical kit comes in. It’s not just a trigger – it’s a complete Duty/Carry kit and Action Enhancement Trigger rolled into one drop-in package. No gunsmithing degree required.
Apex Tactical builds this specifically for the S&W M&P Shield 45 and Shield 45 M2.0. That includes the original Shield 45 and the updated M2.0 frame. The kit replaces the factory hinged trigger with a solid, billet aluminum trigger body. That’s right – no more plastic hinge. You get a smooth-faced trigger with a center-mounted pivoting safety that keeps the factory safety values intact. It’s a straight upgrade, not a compromise.
What you’re actually getting:
- Drop-in fit – no filing, no fitting, no headaches. Pull the old trigger, drop this in, and you’re back on the range.
- Reduced pre-travel and over-travel by roughly 20% – that means a shorter, cleaner pull with less wasted motion. Your second shot comes faster.
- Pull weight around 5.0 to 5.5 lbs – right in the sweet spot for duty use or daily carry. Not too light for safety, not too heavy for accuracy.
- Shorter over-travel and a more positive reset – you’ll feel a distinct click when the trigger resets. That’s the kind of feedback that keeps you on target.
- Smooth face trigger – no serrations, no sharp edges. Just a clean surface that feels natural under your finger.
- Pivoting safety – it’s the same style safety used in many modern pistols. It won’t let the gun fire unless you’re pressing straight back.
Why this matters for your Shield 45:
The factory trigger on the Shield 45 is functional, but it’s not what most shooters would call “nice.” It’s long, spongy, and the hinged design can feel inconsistent. Apex Tactical has been sorting out S&W triggers for years. They know the platform inside and out. This kit takes the guesswork out of trigger upgrades. You get a predictable, repeatable pull that makes it easier to shoot accurately under stress. That’s exactly what you want if you’re carrying for self-defense or running drills at the range.
Installation notes:
This is a drop-in kit, but you should still follow the included instructions. Apex includes everything you need – the trigger, the sear, springs, and the necessary pins. If you’ve changed a trigger before, you can handle this. If you haven’t, it’s still straightforward. Plan on about 20 minutes with a punch and a small hammer. Some people use a slave pin, but you can get by without one. Just take your time.
Compatibility:
Fits S&W M&P Shield 45 (all variations) and Shield 45 M2.0. Does not fit the Shield 9mm or .40 – those are different frames. If you’re not sure, give us a call at the shop. We’ll sort you out.
Price: $165.00
That’s a solid deal for a trigger kit that would cost you more if you bought the trigger and the Duty/Carry kit separately. Apex Tactical doesn’t cut corners on materials – the aluminum trigger body is machined in-house, and the springs are heat-treated for long life.
