Buy it cheap, dump the stocks, and hopefully, it shoots well. Then use it was a truck gun.
Bought one something like that a week ago. Cleaned it up and changed the grips. It started life as a Colt New Service in .455. Someone chopped the barrel and turned it into a .45 Colt. Shoots well, will make a good truck gun or night stand gun. All heads turn at the range when it goes off!
I would be tempted to Fitz that one...
