Felt pretty good after swapping out front sight on my 617....
punch the pin out; remove front sight and replace with new one; use cool new drill bit with Dremel and drill hole slowly from both sides (as these front sights aren't pre-drilled); put pin back and pewpew on my way.
So I wanted to try a Hiviz front sight now.
Punch the pin out
Remove the front sight
Put new one in
Start slowly drilling....snap goes the bit with a piece lodged in the unfinished hole.
Not to worry! I bought two bits...flip revolver over and start slowly drilling from other side.
Snap goes THAT bit as well, with a piece lodged in that side too.
I look over my shoulder both ways (empty garage) and say Why not, this will work fine as is!
200 rounds and didn't move. It'll probably outlast me.
(no clue why it happened 2x, first effort to put new sight in was flawless)
