Honestly, I don’t know that the level of retention is any better with the MIM clip. I have read that Lynch clips have strong retention if that’s what you’re going for.After almost losing my 31 the other day due to the factory clip being too loose and it slipping out of my pocket, I ordered one of these to give it a try. Hopefully this will work better. The Glassblasted CRK's seem to slip out of the pocket easier than the original blast.
