I recently bought a 930 JM Pro and are having some issues and was wondering if anyone else has the same issue. 1st issue is the for end is somewhat loose and wobbly. I took it apart and the retainer is intact so now I really don’t know. 2nd issue is the lifter seems to be stuck. With the bolt closed if I push in the bolt catch and hold it in I can operate the lifter freely but when I let the bolt catch go the lifter will come down and lock into place. Any ideas would be appreciated
