If you have a prehensile trigger finger and an exquisite sense of timing, you might be able to pull off such a stunt. If the gun is a 12 gauge, and both barrels fired at exactly the same instant, you would then be firing the equivalent of a 6 gauge. The recoil, of course, would be double that of a 12 gauge. You would probably have ample time to contemplate the wisdom of such a stunt from your seat on the ground. I have had an imported 20 gauge, very lightweight and with a steep drop to the stock, fire both barrels without consulting me once. As unpleasant as that experience was, I am sure that the same thing in a 12 gauge would be even more uncomfortable. Be careful what you ask for. First, the 311 is a SxS, not an O/U. And it's easy to fire both barrels at once by using two fingers. I've done it with my 16 gauge and it doesn't kick that bad.

The front trigger opened the breach.

It would top out at $250 as a mantle decoration. Unless you mean a Parker Brothers shotgun. Then it could be several thousand dollars.

Generally, no. Barrel sets are individually fitted to the frame and will not just drop on. sales@countrygunsmith.net
