I bought my first citori (used) from a friend recently. He said it wasn't shot much at all and was in good shape. I've shot about 6 rounds of skeet with it, without a hitch. Today when I went to shoot, it wouldn't lock closed. The top lever stayed to the side and the triggers didn't reset. The barrels look aligned with the receiver but the lever could not be moved toward the center. I figured maybe it was dirty or just needed to be lubed. We took the stock off and it looked very clean but dry, so we lubed it. With the barrel and stock off, the lever came back to center (and the locking bolt moved forward and back as well) but still when the barrels were mounted and receiver closed, the lever remains to the side. Like somehow the locking bolt isn't completely engaging in the groove on the barrels, holding the lever out to the side. Any help will be appreciated.
