Gil, I would guess $150-200 if they knew what had to be done. Gunter Pfrommer would be a likely prospect for that job if you explained what had to be done. I did the process on a circa 1913 20 gauge nickel steel gun with 2 1/2" chamber and it worked well. Strange thing about the M-12 is that even the 3" heavy duck model has an ejection port that is not even 2 3/4" long ,as I recall. You can only open it to the edge of the chamber ring maximum, but it works. Regards, Marcus

What I don't know about M 12s could fill volumes, as I've never been a pumpgun shooter. However, I can offer that very few 2 3/4", advertised length, shells are the same length. We discussed this on here some years ago. I cannot remember which available loads were the shortest but there was a significant difference in brands and loads. If you decide not to get the gun modified to handle longer shells it might be worth doing some research to try and find that thread. You just might find a commercial load that will work well as is.

The 16 GA M-12s seem to be a law unto themselves.

OTOH, I have a 1914 Model 12 -12 GA that is original with a sold rib and checked stock and forend.
It is a born turkey-duck gun that has slain many from VA to AL.
It is not ready for retirement at 110 yr and counting. Digests everything smartly, but 3 in shells...
originally from near Chesapeake Bay

All 12 gauge Model 12s were made with 2 3/4" chambers. Smaller gauge (16, 20) were short chambered. Simmons used to do the 2 3/4" chamber work and may still do it. Might want to talk to them about it.
1916XE- If your stock has not been altered, pull the butt plate. You may find TOURN. stamped into the wood. That will indicate that you have a Tournament Special. From your description of your gun it sounds like that is what you have. Is yours a straight stocked gun?
