God willing, my 3 inch GP100 will arrive Monday. I was wondering what you guys thought of shooting Speer's Gold Dot .38 +P, 135 grain round in a three inch barrel. This ammunition is intended for short barrel revolvers. Speer told me their test barrel was 2 inches and 4 inch barrels were considered standard. How would this ammo function in a three inch barrel? Any damage to gun? Thanks in advance.
