I spoke with an instructor type a while back about replacing my barrel to pick up a bit of accuracy. He advised that the stock barrel is ok, but most of us shoot ammo that is less than ideal (how good is that bulk WWB from Wally World?). By switching to a higher quality ammunition or working up a good practice load, you'll find the gun is much more accurate than you might think.

I'm not saying my G19 turns into a laser when I shoot Gold Dots, but I do notice an improvement over bulk 9mm.
