I have a couple extra super safeties available. Went with these because they seem to have the fewest problems out there between all the different versions that are available.

They are D2 tool steel. The kit comes with the lever, cam, and rounded detent. They also have a CNC cut trigger so you don't have to worry about modifying the trigger you already have. Best way to reach me is through a text message. Shipping is available for cheap as well if that works better.
