My EMP is fantastic. It uses leather gear for Commander-length pistols just fine, and yes, the mags are different, but SA gives you a coupon when you buy the gun, so just buy 3 or 4 extra mags and have fun. Mine is carried daily, and has had about 1500 trouble-free rounds down the tube. I use +P+ for carry, and shoot them in practice occasionally. Mainly because I am a .45 person, and the EMP seems to like the Federal 147gr +P+ really well. I haven't used it, but the gun comes with a FOBUS-style holster in the case.
Enjoy it.
