I decided I would try carrying a full size as opposed to my G19. I'm carrying in a Crossbreed Supertuck. The issue is that twice now, I've pressed the Mag release when driving, causing the magazine to fall out or release when getting out of my car. I guess it's the extended magazine button pressing between my back and the seat. What is a good replacement mag release for concealed. I looked at my 19, and it's just so worn down it works fine if I carry IWb backside. Do you sand it down? Any suggestions?
