Wouldnt be worth it to me if I already had a gun with a 32" O/U...if you want to make/have a combo its probably more cost effective to sell off the current gun and purchase a combo that has matched number to the frame barrel sets..this will always be worth more resale wise too should you need to move to something else
Worth it if you want new, but there may be a used Bbl that can be fitted for less they want $150-$300 to fit the Bbl to your reciever. See if a dealer will sell you one wholesale, or has one off a new gun, sometimes no fitting is required due to the CNC Mfgrng.
The Italian Govt Proof house requires all barrels to have different serial numbers so even on a new combo they won't match. Perazzi's are generally one higher but Guerini, Zoli and others are more random. DGG
