with a variety of brands that sell 7, 8, 9 or 10 round single stack mags are they all compatible with all makes of handguns or are they specific to certain brands only? say sig mag in a colt or colt in a sa? regardless of who makes the mags for the brand what do i need too know? other than compact 1911's or a short grip models what do i need too know when deciding on a mag? just wondering as it seems the mag catches are all the same location as possible standardized in a way?
