Not a fan of hybrid holsters. My MTAC Minotaur collapses when tucked in, resulting in unreasonably tight retention. I had to back the screws almost all the way out and file down the retention nub to have a smooth draw. I can't imagine going for my gun and being unable to clear the damn holster.
Sorry for the rant. Anyway, have you thought of making more holsters? I have another kydex holster made by ready tactical and purchased from SKDtac for my G19. It's the heat:
This holster makes carrying my G19 both convenient and concealable.
I've been poking around looking for a kydex holster of similar quality for my P30S and recently bought another IWB from blade tec--hopefully it will measure up.
Ugh. Started ranting again. My point is--have you thought about making some light bearing Kydex holsters? If so, I would love to see your work. Holster making sounds like a lot of fun.
