ok so hypothetically speaking .. say all interested parties can't come to an agreement over the DT11 proof and worse case that beretta either make a UK spec model (within uk proof) or change them worldwide (can't see happening) .. or pull dt11 from uk sales (again can't see happening) .. will any changes to the barrels make the gun shoot completely different ?? I personally can't see a company like beretta not seeing this problem arising and no doubt they will have a very good argument ready for said meeting
