I looked at the EMP for awhile, but the fact that it requires Springfield mags made me look instead at three other pistols for the same purpose:
Colt Defender 9mm
Colt New Agent 9mm
STI 3.0 (Lawman or Spartan)
Each of those you can buy mags from anybody and not rely on Springfield for their mags.
Springfield customer service, though, is GREAT!
