doesnt feel like the sturdiest option, however for my purpose im content.  no one will be able to operate the weapons im using these on without the key or some time.  if the weapon is stolen it can easily be removed.  i do appreciate that all 3 are keyed the same.  it came with 6 keys also.  they do feel flimsy though.  be careful not to break them in the lock.  i did not have any issues with the lock scratching my weapon.
