I picked up a Ruger SP101 .357 Magnum in a trade today. Overall, the gun is in excellent condition, but the front sight is boogered up pretty bad. It looks like someone dropped the gun on the sight because one corner is caved in. Also, someone dremeled the finish off the top and rear of the sight so it is silver and very hard to see. I know I can probably just order a replacement front sight from Ruger, but if I am going to replace it anyway, what aftermarket sights would you guys suggest I take a look at? Here's the obligatory pic of the newest member of the family.
