Therein lies the problem IMO
I'm following what you are saying. The guy I sold my G30 to, a couple years ago, was over the other day shooting. Before we went out I asked to see one of his mags with the Scherer extension. It did fit, but there was a noticeable gap, between the grip of the frame, and the top of the extension. Guess I'll just have to go with the Pearce, 29 specific extension. Thank you for your help.
