I dont know if its a known problem or not . I never heard much about the Redemption since its been out . I was reading on modern muzzleloader about the hinge pin and thatd what made me decide to check it out . My gun when open has wobble but when locked up it is very tight . Maybe its a known problem to others . Either way it will be interesting to see who bought out LHR and if they honor warranty work should the need arise
