I am thinking about getting a hybrid (kydex) holster iwb for my mp340 BUT I'm really SCARED that the kydex will destroy the finish??? Anyone have any experience with this? I currently have a sideguard iwb holster for this gun but it is not comfortable.. I don't know if its the holster or if jframes in general are not ok for iwb? I'm not looking for this jframe to be a pocket gun but I am wondering if the cylinder is just not really conducive to iwb carry? I see the crossbreed and kholster make jframe hybrid holsters.... Any thoughts????
