Well I installed a Springfield 9mm conversion kit on my GI 45. The problem is, it wont feed properly. The nose of the bullet is hitting the ramp of the barrel chamber. I know I have to take my pistol to a gunsmith. The slide and lock up seems to fit well, but im no pro to really tell if it does. Im no expert here and have little 1911 vocabulary. But what type of job do I ask for? And, most importantly, how much is this type of job going to run me?
