I am very happy with this barrel - Lone Wolf Arms AlphaWolf Glock 27 .40 S&W Barrel

I was leery about buying this barrel because of a bad review by someone else but I am glad I went for it. Mine is running well with reloads that have been trimmed, sized and de-bulged. I feel safer shooting reloads with this barrel than the stock Glock barrel because it fully supports the cartridge where the Glock barrel does not. Glock says "do not shoot reloads or lead bullets thru their barrel but you can with this barrel as long as you follow all of the reloading protocols properly and don't load too hot. Also, you have to hold a .40 S&W tight because a limp wrist can cause jams.
