The Short Barrel load was, of course, expressly designed for use in the shorter barrels and does very well in testing. However, I haven't run across any actual shootings with it. Several departments are using standard Gold Dot .45 ACP for both service pistols and shorter-barrel autos issued to detectives and administrators, and I've heard of no problems. Might just be a coin toss. I personally wouldn't worry about carrying either in one of my Glock 30s.
