I guess I'm going to hope theres a Custom barrel company that can produce a barrel for 4506. Ive exhausted my search on internet for S&W original. Anybody else found a solution for this problem?

I have 4506 barrels new old stock. .346 wide hood. part number 236130000. $70.00 ea 8.00 shipping

4506 barrel will work in a 4505 correct?

if so how do i order

Do you still have the 45 barrels? I need a 4506-1 barrel the part number is different than yours not sure if it will work?

I got lucky when midway came back in stock with barrels. I managed to get one before it sold out, and had a local machinist cut it to the dimensions I needed.
