I had decided to get rid of the bolt top lawyer safety on my Rossi .357 - wings and all - so heres how I did it. YMMV.
In my scrounge box, I ran across a couple of Remington 1100 issue crossbolt safety buttons, that I had kept after converting some fellas guns to Giant Head or left-hand safeties.
Sooooo, I chucked the end of one into my hand drill. I suppose a proper-sized screw could be used instead.
Then, I started up the drill, and held the safety against a file for awhile
Now that it's turned down, I'll see if it fits a lawyer hole
I then filed a notch for the retaining pin
And cut off the part that won't stuff into the lawyer hole
Almost "off"HOUSTON - WE HAVE SEPARATION
File down the teat, off the cut & polish it smooth
NOW it fits in the lawyer hole, much better !
Done, except for bluing - IF wanted.
