If you can 'try-fit' it in a FTF you will know, if you have to send for it, it might fit, or not. I had to lightly shim one, and two other barrels swap frame to frame but I have to shim the forearm spacer to wood fit to get the forearm tension right. This means having dedicated forearms only for convenience or if you want the option of both barrels.
Or, wait it out and buy a whole used gun in the choke you want for just a few dollars more?
