While at the Ruger Gathering I broke out my newest Bearcat acquisition and noticed that it was 'notchy' (is that a real word?) when I cocked it. It didn't occur each time so I put it aside and figured I'd work on it later. Today is 'later'. Seem the previous owner had disassembled it at some point and when reassembling it he/she installed the cylinder latch plunger with the spring against the latch rather than the plunger against it. Reversed it, checked, and the notch is GONE.
