I recently acquired an EFK Firedragon Conversion barrel for my XD. (.40 to 9mm). I shot it for the time last week, and it shot consistent groups but the groups were low when compared to the stock barrel.
I would love some step by step instructions (with lots of diagrams, etc) to show how I fit this barrel to adjust the aim. I sure don't want to remove to much metal, or remove it from the wrong place - so any suggestions would be appreciated.
