another old photo review. The EMP was one of my CCW's. I bought it to replace my Kimber Tactical Ultra II. It's design came from Springfield's .45GAP Defender that they had designed, but scrapped the project. A few years later the EMP (Enhanced Micro Pistol) was born, with 15 "re-engineered" parts for the shorter 9mm and .40S&W round. These parts are: slide frame left grip panel right grip panel firing pin firing pin spring extractor plunger tube plunger spring trigger magazine tube magazine follower magazine spring magazine base plate magazine base pad The grip frame is about 1/4" smaller in circumference than the .45ACP Micro Compact. This reduction center's around the smaller cartridge used. The grip safety is fit similar to Springfield's other production guns. When the EMP was new, the slide was tightly fit the the frame. After ~2000rds, it has loosened up just a little, but still much tighter than my Loaded. The barrel locks up tight and the bull barrel has no movement. The hard anodized alloy frame is machined much nicer than the Loaded, and similar to the Trophy Match or TRP. I have not personally confirmed it, but have read that the EMP frames start as US forged frames.
