I have two J-Frames, a 642 and a 60. The milled in standard front sight can easily be ground off and an XS tritium sight added on. I purchased those sights and my gunsmith installed for $30ea. The directions are in the XS box and on-line how to do that.....but you need the equipment. Some may say you don't need sights on a snubby, but i ain't getting any younger and I really like them. And much cheaper than buying the scandium frame version with those nice sights, though I wouldn't mind picking up one just because.
