Will a Glock 20 Gen4 holster fit the Glock 20 Gen4 MOS?

Often, but not always. 258 of the holsters here are matched through the Glock 20 Gen4 listing rather than the Glock 20 Gen4 MOS 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 20 Gen4 MOS, 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.
