A LOT! These were in production for many years, and a very popular gun. Check with Customer Service at the Ruger website for some specific answers.
mine is an 82xxx number and its a mk1. The best way to tell is the release for the lever. MK1 has 2 lugs you push towards the muzzle. The mk2 just has a button you press. Hope this helps
