Just personal preference, but I like the 147gr bullets for my short barreled Kahr. Ranger T's and HST's are what I favor at the moment.
And just FYI, I emailed Speer a year or so back and asked how the Short Barrel +P Gold Dots and the regular +P Gold Dots compare out of short barrels. The rep who wrote back said the regular +P's would work just fine with a short barreled handgun.
So if you're looking to stay with the lighter, higher velocity loads, don't waste money with the Short Barrel Gold Dots, just look for the 50 round boxes of the regular +P Gold Dots.
Give a man fire and he'll be warm for a day.
Set a man on fire and he'll be warm the rest of his life.
