So long as the barrels are still solidly attached to the top and bottom ribs, cutting it down is not going to make it 'Fly Apart'. Take the barrels off the gun and hang them on something (your finger will do) by the barrel hook. Then take a pencil or something like that and tap the barrels up and down both sides listening for any dull notes from the resulting ring. If something sounds funny, the solder holding the barrels to the ribs may be loose. Good luck...Geo
