Likely, the right answer isn't replacing the barrel, its probably spending more money on ammo and practicing.
If your groups are so tight and perfect you don't believe you can improve your technique any further, perhaps some hardware upgrades will help.
I am shooting at my own time. I shoot factory ammo and my groups are good but I was just curious if an aftermarket barrel might tighten them up a little more. I was actually looking at a Lone Wolf extended ported barrel. Maybe I would be better off changing the factory sights.......although I like the factory sights on my G17.Are you shooting at your own time or timed?
