I don't know if this has ever been posted before but I was curious. I have some pre-ban sig mags for my P226 that I got back in 1993 and was wondering if it would be legal to install a mag extender to these mags. They would increase the capacity. They are pre-ban and not the 10 rounders. My thought is that I am not making hi-cap mags because they are already hi-cap (standard cap) mags.
