Noodling around with the Webley .32, I suddenly got an idea.
One of the oddest features of the little Webley/H&R automatics is their thumb-operated manual safety. It's located fairly far forward on the gun to those used to Browning-pattern pistols and, worse, its operation is backwards: Up is for "fire" and down is for "safe".
However, the lever is a long and thin one and almost seems to be designed to keep the thumb from fouling the slide as it almost certainly would if the positions were reversed. Obviously I need to go do some shooting with this thing.
