Pistols show up quite a bit in accounts of frontier travelers - my copy is in storage, but Eslinger's Running Mad for Kentucky, a collection of period travel accounts, has quite a number, IIRC. My favorite one is the guy that described himself as looking like Robinson Crusoe, with two pairs of pistols in his belt, a rifle, and a sword.
This guy apart, it wasn't very usual to carry pistols in the belt in the 18th century, and they were usually carried either in saddle holsters or in coat pockets. A nine-inch barrel would be a (saddle) holster pistol. Backcountry and frontier culture - including Southeast Native American culture - was very horse-oriented, something that tends to be overlooked these days, and most serious traveling was done on horseback, so the most likely role for your pistol is to be carried around on a horse when on the road or hung up in the cabin between trips. Not something you'd wear around the farm or hunting.
