I bought Bar-Sto barrels for all my Glock .45's and my life has been the better for it so many range trips I can't even count anymore. The Bar-Sto bbla are not only of 'traditional' rifling but, are of the highest quality in material, machining, craftsmanship and customer care. They sell both drop-ins (no fitting / gunsmithing required, delivered to your door) or, you can send your gun to them and they will custom fit your barrel to YOUR gun, etc. and return it . . . This allows me to shoot both jackedt AND my lead relaods or, if I know I'll just be shooting jacketed, it takes seconds to swap the bbls in and out.
Best o' success!
