I did this to a Beretta A303 in 20ga. I had Mike Orlen do the work and it was excellent and reasonably priced. He did a thin barrel tru choke as there isn't enough material to do much of anything else. Lots of choke makers make tru chokes, but not nearly as many options as a Beretta style choke and they were higher priced. Link to Mike Orlen's contact info and price list.

I believe you will be disappointed if you’re looking for hot core patterns for turkey hunting. If you’re good with even hunting style patterns you may be satisfied with there very limited choke options that will be available to you after threading your barrel.

Steve Rose aka Rose Action sports is the man to ask. He will know and guide you in what to do. He does invector/wincoke

might need to take calipers and measure the outside of the barrel and let him know before you mail it off to him. He is a site sponsor and his info is listed here.

The suitability of threading a cut down barrel generally comes down to two things; availability of the installation tooling for the choke tube thread style and adequate barrel wall thickness to accept the threading.

The Italian guns often have a barrel that is thinner though the mid section (you'll notice if the muzzle end of your barrel is larger where the choke tubes is located). This can limit choke tube threading options on some barrels. To determine if your barrel is suitably for cutting and threading at a particular length measure the outside diameter at the spot you want it cut, and also about 2” behind that spot (in case the barrel is even thinner back there).

Minimum barrel outside diameter required at the choke tube area (last 2” of barrel):

12ga Rem-Choke .845”
12ga Win-choke, Browning Invector, Mossberg Accu-choke .845”
12ga Tru-Choke .825”
12ga Thinwall .805”
20ga Rem-Choke .735”
20ga Win-choke, Browning Invector, Mossberg Accu-choke .725”
20ga Tru-Choke .705”
.410 Invector (1.9" long tube) .525"
