Description
The AmeriGlo GL-112-315 is a front-only replacement sight built for Glock pistols that need more height than the factory setup. It runs a green tritium lamp surrounded by a white outline, so you get a glowing aiming point in low light and a high-contrast dot the rest of the day. At .315 inches tall, it sits noticeably above a standard front sight, which is exactly what you want when you're shooting over a suppressor or trying to co-witness with a red dot.
Where the GL-112-315 Earns Its Keep
The extra height is the whole story here. A stock Glock front sight sits low, and once you thread on a can or mount an optic, that low sight disappears from view. This taller front clears most suppressors and lines up for a lower co-witness with many slide-mounted dots. The blade is slimmer than the factory sight at .140 wide, though the tritium dot stays the same size, so you get a cleaner sight picture without losing that bright glowing reference.
Build and Fit on the GL-112-315
AmeriGlo makes these from heat-treated, case-hardened steel, so they hold up to holster wear and years of use. It fits all Glock models and works with any standard notch-style rear sight, which gives you room to mix and match a blacked-out or plain rear if you're running an optic and don't want competing dots. Keep in mind this is the front sight only, so you'll want a compatible rear to complete the setup.
Installation is straightforward with a 3/16 nut driver, though that tool isn't included in the package. A lot of folks handle the swap at home, but if you don't have the right tool or a sight pusher for the rear, having a gunsmith set it is money well spent to protect your slide finish and get it seated right.

Frequently Asked Questions
Does the GL-112-315 fit my Glock?
Yes, this front sight is cut for the standard Glock dovetail and fits all Glock models. It's designed to pair with any standard notch-style rear sight. Just confirm you're not on a slimline dovetail that needs a model-specific sight before ordering.
Why choose the .315 tall front sight over a standard height?
The taller .315 front is built to clear the height of a suppressor and to co-witness with many red dot optics. A factory Glock front sits too low to see once you add a can or a slide-mounted dot. If you're running a suppressor or an optic, this height keeps your front sight in view.
Is this a complete sight set or just the front?
This is the front sight only. You'll need a compatible rear sight to finish the setup. Many people running an optic pair it with a blacked-out or plain rear so the tritium dots don't compete with the red dot.
How hard is the AmeriGlo GL-112-315 to install?
The front swaps out with a 3/16 nut driver, which isn't included in the box. It's a manageable at-home job for the front sight, but a sight pusher makes the rear far easier and safer on your slide finish. If you don't have the tools, a gunsmith can knock it out quickly.
