10,000 rounds is a pretty short life for a barrel. I would've expected more especially in .45. I've been getting between 50-60K with Schuemann barrels as long as I don't run continuous "Bill Drills" and heat up those barrels until theyre brown. One of my .40 guns is a Dawson build and it's over 61,000 on the original STI barrel. It keyholes with some bullets and is a bit slow but with good bullets (Zero) it'll shoot well enough. It ought to fail any time now....

Worn out, blue/black guns are PRETTY!!!
