I have a Taurus PT140 Millennium Pro that has the indicator on the right side. I didn't take it into account when molding and it has roughed up the inside after carrying for about a week now. I'm going to try to go back in with gum trag and fix it the best I can, but I will definitely consider that in future designs. The Springfield XDm's have never been a problem b/c they are on the top and the sight channel takes care of it.
