Actually, yes I did. I replaced the firing pin safety plunger lever, the guide rod and cap. Shot a couple boxes of ammo thru it then I sold it for $500. The guy I sold it to still has it and carries it as his EDC. It's ran like a champ for him. I saw him this past weekend carrying it.
This one didn't work when I first got it because some jack-wad who probably shouldn't even own a gun felt the need to beat and pry on it. You'll have to view the photos at the beginning of this thread to appreciate the dumb-assery involved.
