Ive got several 1911's Most Colt's couple spring fields a Kimber and a Rock island. I had never thought about purchasing a Rock island with a 4.25 barrel I found NITB for $400.00 and couldn't pass it up. Be fore even shooting it I did some trigger work on it. Trigger stock was 7LB after doing a little work its now 4LB. I took it and my Kimber Desert Warrior 5 inch barrel 5 LB pull to the shooting range to see if I felt a difference in the 2. Surprisingly after 100 rounds out of each of them there were no jam ups, I liked the feel of the Rock island better. Not only was the trigger pull easier but I felt less recoil coming from the Rock island. I was really surprised usually the shorter barrel has more recoil. Is it really worth purchasing a gun for the brand?
