Bruce has done a wonderful job comparing the 9mm Speer Gold Dot round with the 9mm Speer Gold Dot Short Barrel round. Its fascinating to see the difference when shot out of the S&W Shield. Spoiler Alert…. The short barrel ammo really sees mark-able improvement over the standard load. Which is really saying something since Gold Dot is one of the premier, tried-and-true loads available today. I’m sold.
