Yes that is what he is saying. The Tenifer finish will wear a groove in the "slide stop", if used as a release. Then it wont lock open at all, requiring you to install a new "slide stop". I know this because I had to change one for this reason. Use the slide to return to battery, not the slide stop. Unless you want to change the slide stop every so often.your saying if you have an open slide, put a mag in, you shouldn't use the slide stop to send the slide forward? Why would that be bad for the gun? I'm thinking that's what your saying?
