It's never given me any problems with thousands of rounds down dozens of other pistols. This isn't a custom 1911. If you have the money to run premium ammo for target practice great for you, I don't.
I've never had problems with Blazer, Sellier & Bellot, Georgia Arms, Blazer Brass, or PMC -- and those prices are generally comparable to WWB or UMC, and I think they're all better ammo.
(Some folks don't like Blazer Aluminum cased ammo, extraction problems, but it's always been fine in my guns, in all calibers.)
