I have tried many, many holsters over the years and have found the Crossbreed style to be among the very best. I say style because there are several hybrid holsters on the market. I have a couple I would not recommend to anyone. However, My crossbreed mini tuck has been my summer carry unit for my LCP. I tried a couple others and would advise staying away from those that have screws retaining the kydex. They say they are for adjustment but the combination of the leather learning and stretching and the rubber washers getting weak makes for poor weapon retention.
If the crossbreed is a little high for you, try Foxx. Same general design with even more carry adjustment than the CB. I just bought one for my Ultra and the wife's Ruger LC9. I think they are every bit as good as the CB at about 2/3 the cost.
