Recently, in a buy from a private party, I picked up a T/C contender, it's an older one, but, it looks like new. It came with 2-16" barrels, one in .223, the other in 45/.410 it also came with the pistol grip on it. Shooting a 16"bbl .223 with the supplied pistol grip was more trouble that it's worth, so I got online and in short order, found a composite stock for it. While I know this set up is fine for the .223 barrel, what about the .45/.410 barrel? If I used it as a .410, would it be considered a short barreled shotgun? I will say, with the stock on it, it is really handy..
