Thats a Franchi 48al. Browning barrel wont fit.
As mentioned above, steel can be shot out of barrel with a modified choke or more. The 3” guns usually had 30” or 32” barrels and full chokes. Its very rare to find a 30” barrel with a modified choke. Usually the 28” barrels have modified chokes and the 26” barrels had IC choke.
Be mindful that 3” barrels fit on 2.75” guns and vice versa. But never shoot 3” shells if the gun has a 2.75” receiver. 3” guns always have steel receivers and 99% of 2.75” guns have an alloy receiver. There is only one model of 48 that has a 2.75” steel receiver and if I recall it was called the Dynamic-12 and its has no engraving on it.
