Description
The Glock 42 is a fantastic little .380 for pocket carry, but the factory trigger leaves a lot on the table. Overwatch Precision fixes that with the TAC Trigger, a flat-faced drop-in that replaces your OEM shoe, safety tab, and trigger bar as one complete assembly. The broad flat face encourages a straight rearward press, which is a big deal on a small gun where sloppy finger placement pushes your shots off target. Add the small indexing hook at the bottom of the shoe and your trigger finger lands in the same spot every single time.
What Makes the TAC Trigger Different on a G42
The shoe and safety tab are machined right here in the USA out of 7075-T6 aluminum, the same tough alloy a lot of AR receivers are cut from. Both pieces get a Type III hard coat anodizing done to the MIL-A-8625 standard, so they hold up to real carry wear. The whole assembly rides on an NP3 plated Gen 3 OEM trigger bar, joined by 316 stainless steel coil spring pins. That NP3 finish from Robar co-deposits Teflon with electroless nickel, which means slick, grit-free travel and serious corrosion resistance for a gun that spends its life against your body.
Feel and Fit Behind the Overwatch G42 Trigger
Pre-travel and overtravel are both trimmed down for a shorter overall stroke and a cleaner break, without touching any of the factory safety features. The flat face also pulls trigger reach in by about a quarter inch, which is a genuine help if you have smaller hands or just want a more confident grip on the compact frame. It is a true drop-in, so no filing or fitting is needed, though the OEM trigger bar itself isn't tuned by Overwatch. If you want a lighter pull, pairing it with a factory minus connector and a competition spring is the common route folks take.
Bottom line, this is one of the easier upgrades you can make to a G42 and one you'll notice every time you press it.

Frequently Asked Questions
Is the TAC Trigger a true drop-in for the Glock 42?
Yes, it comes as a complete assembly with the shoe, safety tab, and trigger bar already put together. There is no filing or fitting needed to install it. Overwatch does recommend having a certified Glock armorer or gunsmith handle the swap if you aren't comfortable working on your pistol.
Does this trigger make the pull lighter on my G42?
The flat face and drop-in design on their own don't change your pull weight, since Overwatch doesn't tune the OEM trigger bar. What you get is a cleaner, crisper break with reduced pre-travel and overtravel. If you want a genuinely lighter pull, pairing it with a factory minus connector and a competition trigger spring is the usual path.
What's the point of the flat face and little hook at the bottom?
The broad flat face promotes a straight rearward press that helps correct sloppy finger placement, which matters a lot on a compact gun like the G42. The small indexing hook gives your finger a consistent home so it lands the same way every time. Together they add up to more predictable, repeatable shots.
Will the NP3 coated trigger bar hold up to everyday carry?
It holds up very well. The NP3 plating co-deposits Teflon with electroless nickel for excellent corrosion resistance and smooth, grit-free operation. Combined with the Type III hard anodized aluminum shoe, it's built to shrug off the sweat and grime that come with pocket or IWB carry.
