A buddy of mine purchased a 682 and it misfired a 3-4 times every round, due to a light primer strike. Started on the top barrel and moved to the bottom. Has sent the gun to Coles twice, no satisfaction. The first time they replaced the springs, no help at all. Second time they disabled the ejectors, saying that using the ejectors caused the gun to not fully open and thus not fully cock. ??? Has anyone had a similar problem and know of a cure?
