Re: bearcat anyone??
Back in the early 1900s, when you went hiking or camping, your pack of stuff was called your "kit". WW1 British marching song - Pack up your troubles in your old kit bag and smile, smile, smile. So small guns that could easily be packed in your kit were called kit guns. Smith and Wesson made (still does) a 22 on their 32 frame, and called it the 22/32 Kit Gun. Now it is the Model 34, and the Model 63 in stainless. That's why the Bearcat would be called a kit gun. Not because it was made from a parts kit.
