Description

The AmeriGlo GL605 is part of the CAP (Combative Application Pistol) lineup, a sight system designed around one simple idea: get your eye on the front sight fast when things get tense. The front sight combines a green tritium lamp with a photoluminescent lumigreen square outline, and that outline charges off any light source and glows bright once it's soaked up some light. The result is a front reference that jumps out at you day or night. The rear is a flat black notch with a horizontal lumigreen bar underneath, giving you clean contrast that keeps your focus where it belongs, on the front.

What Makes the GL605 T-CAP Different

This is the T-CAP variant, which means it runs a thinner 1/8-inch front blade. The narrower post shows you more of the target on either side of the sight, which helps with precision at distance. AmeriGlo builds the thin front as standard on the smaller Glocks because the shorter sight radius on guns like the 42 and 43 benefits from that tighter front picture. The sights are precision machined from US steel with Swiss tritium lamps, so durability isn't a question for daily carry.

Cover Point of Impact With the GL605 CAP Sights

The CAP philosophy is a Cover Point of Impact system, developed by combat pistol instructor Dave Spaulding alongside AmeriGlo founder Rick Callihan. Up close, you place that bright front square over what you want to hit and press the trigger. The rear notch runs slightly wider and deeper than a stock Glock rear, which speeds up how quickly your eye finds the sight window under stress.

Fitment for the GL605 Glock Sights

This set is cut for the Glock 42, 43, 43X, and 48 across Gen 1 through Gen 5. Overall rear sight height comes in at 0.272 inches. Installation is a straightforward dovetail swap, though like most steel aftermarket sights, a proper sight pusher tool makes the job a lot cleaner than a punch and hammer.

Frequently Asked Questions

Will the GL605 sights fit my Glock 43X or 48?

Yes. This set is cut for the Glock 42, 43, 43X, and 48 across Gen 1 through Gen 5. The same slide dovetail is shared across those slim frame models, so you're covered on all four.

Is the front sight actually tritium, and does the rear glow too?

The front sight is a true green tritium lamp surrounded by a photoluminescent lumigreen outline that charges off light and glows brightly once exposed. The rear bar is painted lumigreen, not tritium, so it charges the same way but won't self-illuminate in total darkness. That setup keeps your focus locked on the glowing front sight where it should be.

What does T-CAP mean compared to a standard CAP sight?

T-CAP refers to the thinner front blade, running a 1/8-inch post instead of a wider one. The narrower front lets you see more target on either side for better precision at distance. AmeriGlo makes the thin front standard on the smaller Glocks since their shorter sight radius benefits from that tighter picture.

Do I need special tools to install the GL605 CAP sights?

These are steel sights that press into the factory dovetail. A dedicated sight pusher tool makes installation clean and controlled, and it's the way to go over trying to tap steel sights in with a punch and hammer. If you're not comfortable doing it yourself, most local gunsmiths can swap them in a few minutes.
