Model 12 barrel change

I've got a Model 12 12ga., made in 1930, which has a 30", full choke, straight barrel. I want to use it for quail and am thinking about changing the barrel to a 28", modified choke, with vent rib. Is this practical? And, if so, where can I find a barrel?

Unlike more modern shotgun designs where the bbl comes off by itself, the Model 12 has a unit construction with the bbl and the magazine pump handle assembly all together. You would need a whole front half of the gun to change chokes.

Or you could get a gunsmith to install choke tubes.

Actually, the barrel can be changed. There is a degree of fitting required, so it needs to be done by someone competent to do that type of work. I put a new, vent rib barrel on a 20 gauge model 12 about a year ago. The Winchester rib requires a rib extension that fits on the receiver and requires that the receiver be milled for it. I would suggest that you contact Simmons about shortening your barrel and fitting a rib and extension to it. They can also install choke tubes and convert your gun to the configuration that you desire. It will probably be more cost effective to shorten, rib, and thread the existing barrel than to find and fit a new one. If you really need to find a new barrel, Numrich ( lists new 12 gauge barrels but they only have 20 inch cylinder bore and 30 inch full choke barrels shown.

please can someone explain what is needed to "hand fit" another barrel to the model 12? why cant you for instance just unscrew the old barrel from the reciever extension and screw the other in? if your using all of the exact same parts except for the new barrel and that new barrel has the exact same chamber dimension of 2-3/4" and its a winchester factory barrel then everything should be the exact same right?
