Anytime you purchase a compact version of just about any manufactured weapon you can use the full size magazine for that particular manufacturer. It would cost too much to put a release or catch slot in a different place for any magazines produced for a particular weapon.
If you buy a compact you have versatility that you do not have with a full or mid size weapon from any manufacturer. With a compact you can carry compact and have full sized magazines (as many as you want) or not but with a full or mid size weapon you are pretty much stuck with what you have! It is almost a non brainer to not own a compact that you can change to a full size firepower just by sticking in a full size or mid size mag!
