I bought this during the Black Friday sale. I haven't done any extensive testing on it, but since pistol barrels tend to last forever, I'm not too worried.
It is shooting a 3" group at 50 yards with plated bullets and no accuracy testing. It also will feed TC bullets, which is a plus over a barrel that needs round nose bullets to feed. The rifling looks clean and the finish is clean and evenly applied. Couldn't be happier.

Purchased the barrel to build a suppressed 9mm AR. Barrels proved to be accurate and we'll made. I am becoming a fan of Green Mountain barrels having bought quite a few of them.

Overall quality is excellent, got some very good groupings with 125gr JHP slugs, wish they did a 10" barrel for a pistol build. But would buy again
