Will a Sig Sauer P320 holster fit the Sig Sauer P320 M18?
Often, but not always. 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 Sig Sauer P320 M18, 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.
