Don't think so? Drive the hammer axle (pin?) out of a Browning Superposed and you'll get hammers that look like hammers rather than picks. Course you could tell that without knocking out the pin(?) because they're not buried in the "box" like those in say the average American boxlock sxs.
The word pin covers a lot of ground. The Brits call a machine screw a pin but a tapered wood screw they would probably call a screw. And then there are the "pins" in any gunframe or lockplate (for instance the five or seven-pin sidelock in which they can be axles for moving parts, columns which support the bridle, or v- spring anchors or studs (I think). And there's the strange tie rod between tangs on a Flues SBT which is both a tapered pin and a machine screw.
And the firing pins are also pins. A useful word for anything that fits in a hole!
