Score High makes a single shot plate that fits on top of the original follower. The stagger feed mag stays in place. Pull the spring and follower, add the Score High follower and put it back together. Sinclair and Brownell's as well as a few others sell them. OR, if you're really into it, you might try getting an adapter/adaptor plate from Sharp Shooter Supply, make a few mods and it will end up as a permanent fix. I've done both.
