I picked up this Mdl. 28-3 at my LGS. I don't know much about Smiths but it was the same price as a new blued Ruger GP100 so I took it. I figured some new grips and a FO front sight and it will be good to go. When I got home I realized that the sights were fixed and not removable. Okay, so is it possible to mill in a new aftermarket front sight (if so which brand you recommend) or just leave it alone. I can only really see the front sight if the room is well lit or outside. Thanks for any help!
