@csdunbar I've tried some of the after market mag extensions (Pearce and some other brand I don't recall off hand) for my G36. Have to say I didn't care for them and switched back to the stock floor plate. I'd say I have average size hands (large glove size). They do add more space to grip the pistol, but for me it felt like it was actually looser and harder to control with these. My hand seems to fit very snuggly up to the rear of the trigger guard without the mag extension which makes things feel a bit more solid. Your experience may vary.
