Thank-you for answering my question.
I've received two replies. Both answer my question with precision. Maybe too much precision.
Maybe this will help ...
Can anyone think of a movie (A Western would be better than a crime drama, which I seldom watch.) where these guns appear? Or better yet, where one is shown being used. (close up, not some guy on top of a mountain)
A suggestion...
If it wasn't a revolver, what could it be?
Perhaps with an overall picture in my mind, I'll be able to fit the pieces of the puzzle together.
Cheers, PW.
P.S. Maybe the reporter who wrote the news item knows less about this than I do.
P.P.S. This 'cocked' stuff -- is it where the term "going off half-cocked" comes from.
P.P.P.S. I've used the term 'cocked' to mean 'crooked' or 'slanted', such as "he cocked his head to avoid bumping the tree branch." The British sometimes use the word in a bragging sense, like the 'cock' or rooster crowing.
P.P.P.P.S. After reading your reply over and over and over, I think I get the idea. Does Clint Eastwood's Dirty Harry use a revolver? (I though Harry used a 44 and the fat guy sat on a 45.)
