Is "Big Fork" in the sentence the name of a kind of pistol?

Its a place!
The capital letters for a place name , and the phrase "a good fifty miles south of here " are a significant clues don't you think ?

(He's dead out by Big Fork,) would suggest to me the deceased is buried near Bigfork (one word) ,Montana.

Thank you very much!

Or the Big Fork (2 words) river or State Forest in Minnesota.
