Storm Lake Barrel

[REDLINE]

Should be a great barrel.  KKM claims an extremely polished bore surphase via their button rifling process.

Have any of you guys used an EFK Firedragon barrel? I had an opportunity to buy one when I got my G21, but passed because of limited funds. It was the only Glock replacement barrel I've seen that actually had a better internal finish than the factory Glock bore; it was glass smooth all the way through. I guess they use EDM for their rifling. I'd like to try one someday.

I'ld be curious to know how much chamber support the EFK barrels have compared to others like Storm Lake, KKM, and Lone Wolf.
