^^ this and I have 0 complaints with either of my barrels as well. Now if someone would just come out with a dam 22lr conversion.^^This. Unless they just recently changed, the barrels were Storm Lake Manufacture and 'branded' for Pistol Gear sales.
Fine barrels, I have the Pistol Gear drop-in fits for XDm40 to get 357SIG and 9mm conversions. And not overpriced.
