I've been buying factory fresh and reloaded ammo from Miwall for many years. They're a regular fixture at the gun shows here and I can't buy ammo much cheaper anywhere.
I haven't used their reloads in my transferable guns in some time, but not due to any problems I've ever had, just my choice. I did shoot several thousand rounds in my first M11/9, so I can say it's good to go in my limited experience. I still use some of their lighter loads in my wheel guns. .38 Special in my .357 magnums and 44 Special in my .44 magnum.
