I'm sorry - I am so computer illiterate it's amazing I even got on to this forum. I would have to consult my wife to post photos and she's recovering from surgery.
I just took about 1/3 of the length of the safety lever off with the dremel, then using a very sharp, cone shaped bit (that is actually made for metal) I took my time and lots of small "strokes", rounding the end off so it replicated the contour it had originally. Using a fine grit emery cloth laying flat on my bench and backed by a piece of cloth for cushioning I stroked the end until it was smooth and rounded. You really can't tell it didn't come that way.
At first when I got the safety back on the gun I thought I had taken too much off but it takes so little leverage to flip it on and off you don't need much there.
