Guns during the Regency were sometimes things of beauty, like the one I describe in The Bachelor that Thorn offers to Joshua as payment for his being bodyguard to Gwyn. If you want to see what it looked like, I based it on an actual set of dueling pistols, a picture of which is on Pinterest here and here. I also have an image of Joshua’s seven-shot flintlock pepperbox pistol, made by Henry Nock of London around 1800, which looks big enough to use as a club after you run out of loaded barrels. Of course, it would take you a while to run through them all since the barrels had to be turned by hand! My Pinterest page for the book also features a number of blades in canes, pistol canes . . . everything you need to be a bodyguard.
