3rd Gen Colt Detective Special
Hard to find a good IWB holster - especially with a snap for retention which I consider mandatory if you leave your house. Initially the holster seemed way too small (I had gotten used to Kydex for duty use and CC) but after carefully reading the directions and using a vice, I got the Colt in there snugly - and after letting it sit snapped in for a day it fits well.
So… READ THE DIRECTIONS AND DON’T GIVE UP. You’ll be fine.
