I have a Springfield V10 Ultra Compact, it has a 3 1/2 in barrel and the barrel is also ported. Since the short barrel and the ports both reduce velocity I was thinking of carrying +P Powerball, to compensate for velocity and feeding problems with HP's. Now my manual says that the gun was designed for standard pressure ammo and that +P should not be used in barrels shorter than the standard 5 in. But I know people who have done it. Does anyone have any experience with this sort of thing. Will it hurt my gun to just fire a few +P through it and then just carry it in the event I have to use it?
