I'd immediately suspect that the barrels have been cut. If they have been cut, that will dramatically reduce the value of your gun. What is the length of the barrels?
24" so this means chop chop?
whats a chopped Colt sxs go for?? Its also a little loose when locked can this be fixed at a reasonable cost? That's why I was asking about the set screw I was hoping it loosened the larger side screw that its part of the locking mechanism..........
I always guessed 12 Ga because a 12 Ga shell fit nicely in the gun not loose not tight
