I bought a fire dragon conversion barrel for my h&k usp .40. I didnt want the longer barrel with compensator cuts in it, but for 60 bucks i couldnt help myself. So i get it in and test fire it and it wont cycle a new round in bit ejects the spent casing. Still using the dual recoil spring for .40 and the .40 mags. Just wondering what yall think, would cutting the barrel down flush help it cycle better pr do i need lighter recoil springs? I always liked the fact that you can run 9 in a 40, i dont plan on doing it often but if i do i would like it to function properly. Any insight is greatly appreciated.
