Well, looks like I will be the new owner of a single trigger Westley Richards Droplock big bore (or will as soon as it gets to my FFL).

I am excited about it.

I was a little hesitant to not have double triggers (all my other doubles do and I totally understand the piece of mind of have two separate locks) but I think you are in pretty good shape with WR's select trigger mechanism based on what I have read. Hell, I noticed that Hemingway's .577 NE was a single trigger Westley as well when I was doing research for this question. Never noticed that before. He and Sutherland never seemed to have any trouble with them.
