I have a LWD barrel for my 19. I am happy with it. Just about all manufacturers disclose against reloads since there isn't any regation on recipes, consistancy and reliability. Its kind of a CYA sort of thing. The way I see it is if you bought a barrel and had a problem, which is unlikely, thing thing to say is you always use factory ammo. They will never prove you use reloads unless you offer this info. I looked at getting a 10mm barrel for my 30 and SL seemed to be the best deal, but I never got one.
