Questions
Which holsters fit the Glock 21 Gen4 without a light?
72 holsters from 9 makers list the Glock 21 Gen4 without a light, including Alien Gear Holsters, Blade-Tech, T.Rex Arms, Black Arch Holsters, C&G Holsters, Clinger Holsters. 13 name the exact model on the product page; 59 are listed with looser wording or through the base model, and each one shows the maker's quote so you can judge it yourself.
Will a Glock 21 holster fit the Glock 21 Gen4?
Often, but not always. 57 of the holsters here are matched through the Glock 21 listing rather than the Glock 21 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 21 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.
