Questions
Which holsters fit the Sig Sauer P320 M17 without a light?
129 holsters from 14 makers list the Sig Sauer P320 M17 without a light, including Alien Gear Holsters, C&G Holsters, Four Brothers Holsters, T.Rex Arms, Tenicor, We The People Holsters. 37 name the exact model on the product page; 92 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 Sig Sauer P320 holster fit the Sig Sauer P320 M17?
Often, but not always. 60 of the holsters here are matched through the Sig Sauer P320 listing rather than the Sig Sauer P320 M17 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 Sig Sauer P320 M17, 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.
