Questions

Which holsters fit the Glock 23 Gen4?

135 holsters from 13 makers list the Glock 23 Gen4, including Alien Gear Holsters, T.Rex Arms, We The People Holsters, Urban Carry Holsters, BlackPoint Tactical, Bravo Concealment. 40 name the exact model on the product page; 95 are listed with looser wording or through the base model, and each one shows the maker's quote so you can judge it yourself.

Which weapon lights have holster options for the Glock 23 Gen4?

Makers list holsters for the Glock 23 Gen4 with Streamlight TLR-1 (32), SureFire X300U (28), Streamlight TLR-8 (22), Streamlight TLR-1 HL-X (20), Streamlight TLR-1 HP-X (20), Streamlight TLR-7 HL-X (20), SureFire X300T (20), Streamlight TLR-1 HL (18). Light-bearing holsters are cut for one specific light, so match the exact model.

Will a Glock 23 holster fit the Glock 23 Gen4?

Often, but not always. 64 of the holsters here are matched through the Glock 23 listing rather than the Glock 23 Gen4 by name. Makers usually mold one shell for a model family, but generation changes to the trigger guard, rail or slide can break retention. Prefer a holster whose listing names the Glock 23 Gen4, and read the quote before buying.

How does holstercheck verify a fit?

I crawl each maker's product pages and record the gun and light named in the variant list or compatibility text. Every result shows that text with a link to the page it came from, and the date it was last seen. Loose wording is marked as such rather than hidden, and readers can report whether the holster fit their gun.
