Get a single shot follower that fits on top of the factory follower.
Or, pick up a single shot sled, remove the blind mag and fit it to the slot in the bottom of the action. May take a little fitting but should be pretty easy.
If you can't find/get one, let my know. I've got 2 new ones, just in case.
SSS has both. That's where I got mine. SSS can be hard to get in contact with at times so keep trying or PM me and I'll bail you out if I can.
