David:-- ..If you didn't remove the skin all over the lever top surface, it probably won't blue right for color ...........you could gently bead blast it on low pressure, then take it down with 400 w/d for a decent surface, then hot blue it, should be o.k.

You've seen case colored guns that have been blued....some look real lousy and some blue o.k., but still look nasty to me, JMO.

Did you file all over the top surface while reshaping it and remove all the case skin...?....

Hope this helps.....

Best,

Doug
