I had a firing pin issue that cost me a whole season +, I took it to smiths, sent it to the factory, in the end it was a sharp old buddy of mine that figured it out. Not the same failure but the fix for me after that, because I couldn't trust the gun was I went out and bought the most it reliable gun that was just out of my price range and it has never failed me, the other gun works well now but I will never compete with it now. My GF competes with it and loves it. Point being I was so afraid off that repeatedly failure that I would never have kept shooting if I hadn't changed guns mental is the hardest part of the game, do whatever you have to, to stay in the game!!
