Tore mine apart again and cleaned it all. Hosed out behind the fingers that release the shell from the magazine. There was some grit in there. Wiped the inside clean. Removed the mag spring, wrapped my barrel brush with a paper towel and swabbed it out. Reassembled and all is fine. Stored muzzle down for a few days for oil drainage. I'll tear it back down in a few days and wipe it dry again.
