I don't have the gun or the holster yet, but am ready to purchase the 10mm P220 Legion. The specs look like it's slightly wider than the .45 P220 Legion, so I'm curious if it'll fit in Galco's Jackass Holster. I reached out to Galco, but they haven't tested the holster with the 10mm, so I'm hoping someone here has tried this and can advise. Thank you

Correct, slightly wider on the 10mm. Could you wet the holster, stuff it in and make it work? Probably, but that would be up to you.

Thank you; I'm thinking of sticking with a .45 (bidding on a Equinox right now) and picking up a SA Ronin in 10MM
