This here is an old 17th century(ish) pistol, modeled as separate parts for easy printing.
I was inspired by many different models, so this is not an exact replica of any particular pistol.
I printed this in WoodFill and BronzeFill to get the look and feel that I was after, but you can print it in any materials you like!
Only some parts need support. These parts are both the wooden bases, the handle metal and the knob.
The rest should print fine without supports!
The parts tolerance is quite small, so you probably need to take out your knife and trim them a bit to get a better fit.
