I recently purchased a Stoeger Coach Gun, I took it out for the first time and the stock cracked. I have been trying to find a replacement stock but I no one seems to stock their parts. Where can I find replacement Stoeger parts, and is it normal that the stock split or is that something I should be concerned about? Also, the gun is set up so that both barrels could potentially be fired at the same time, is the gun made to do that or is that damaging to the gun/dangerous to the shooter?
