After putting a 4.5" barrel on my G32, I found a significant increase in velocity with many loads. One was the Corbon 357 Sig 125gr. JHP which was shooting close to 1,450fps. I did not shoot it for accuracy (precision)only having a few left and figuring how bad could it be for SD. After purchasing over $300 worth, I was at the range today with a 3" Shoot-n-See target in the middle of an 8.5" X 11" piece of paper. The first shot was not even on the paper at 15 yards off of sand bags. In fact, 4 of the 20 shots did not even hit the paper and the rest were scattered all over the paper. Lest you think it may be me or the gun, both factory Speer GD's and Buffalo Bore GD's shot one ragged hole about at the point of aim. Has anyone shot the Corbon 125gr. JHP for accuracy? I did not have the factory barrel with me to try, but the gun shot fine with HST's and Ranger T's also.
