OK, I'm stupid to the term. What's a "Hillary Hole"? I presume some kind of lock thingiemabob.
It's a childish invective used by some to refer to the internal lock that S&W began incorporating into their revolvers in 2001. This was shortly after Tomkins PLC entered into the notorious "Agreement of 2000" with the Clinton Administration and the internal lock requires a small hole in the left side of the frame, hence "Hillary Hole".
