I have never regretted changing a barrel, did 3 or4 on custom 1022 rifles, but haven't most of us, a very custom charger barrel, it cost more than the new gun, and my M1941 Marine Corps, I had bought a new barrel for my 1903 then desided to use it on the 1941 build. Every other firearm I own sports it's original. They all do what they are supposed to, that's good enough for me.
