Description
Factory Glock sights get the job done, but if you're running a suppressor or a mini red dot, they sit too low to be useful. The ZEV .300 Sight Set solves that with a taller front and rear built specifically for co-witness setups, giving you a clear reference over a suppressor or through the bottom of an optic window. Both sights are machined from steel and finished in an all-black, glare-free profile, so there's nothing shiny to distract your eye when you're focused on the target.
What the .300 Height Actually Buys You
The ".300" refers to the suppressor-height dimension, and it's what lets these sights clear a can or line up with a slide-mounted dot like a Trijicon RMR. Depending on your optic and mounting plate, you'll land somewhere in the absolute or lower 1/3 co-witness range, meaning your irons are right there as a backup if the dot ever goes dark or the battery quits. It's a smart setup for anyone who trusts a red dot but still wants iron sights they can fall back on.
A Cleaner Sight Picture with the ZEV Co-Witness Set
The rear notch measures .140 wide with a .145 depth, which gives you plenty of daylight around the front post for fast, repeatable target acquisition and quick transitions between targets. The serrated front post keeps glare down for a crisp, defined picture. There are no colored dots or fiber optic pipes here, just clean black-on-black, which a lot of folks prefer for precision work and blacked-out builds.
Fitment for the ZEV .300 Sight Set
This set is a wide-fit design covering most standard-frame and compact Glocks, including the 17, 17L, 19, 19C, 20, 21, 22, 23, 24, 26, 27, 29, 30 and their variants. It's a straightforward upgrade with the right tools, a sight pusher for the rear and a punch for the front, and once they're on, they're on. Worth noting the rear can run a touch snug on some slides, so a sight pusher makes the install a lot less frustrating.

Frequently Asked Questions
Will the ZEV .300 co-witness sight set work with my red dot?
Yes, the .300 suppressor height is built to co-witness with slide-mounted mini red dots like the Trijicon RMR and similar optics. Depending on the specific optic and mounting plate, you'll land in either an absolute or lower 1/3 co-witness. If the dot ever fails, the irons are right there in the window as a backup reference.
Which Glock models does this sight set fit?
It's a wide-fit set covering most standard and compact Glocks, including the 17, 17L, 19, 19C, 20, 21, 22, 23, 24, 26, 27, 29, 30 and their C and S variants. Always confirm your exact model before ordering, since Glock slimline pistols like the 43 use a different sight cut.
Are these night sights or do they have fiber optic dots?
No, this is a fully blacked-out set with no tritium vials or fiber optic pipes. The front post is serrated to cut glare, giving you a clean black-on-black sight picture. A lot of people prefer this style for precision shooting and blacked-out builds.
Do I need special tools to install the ZEV .300 sight set?
A sight pusher makes the rear install much easier, and a brass punch works for the front. The rear can fit a little tight on some slides, so the pusher takes the guesswork out. If you're not comfortable doing it yourself, most gunsmiths can knock out the install in a few minutes.
