Need a little help with this I'm looking at getting a new to me S&W first up is a model 65 - 3 4" barrel looks vary clean $550
next up is a 686-4 also with a 4" barrel gun looks used not beet up but not as clean as the 65-3 $630 + tax
anyway I'm stuck on witch way to go would the extra $100 bux be worth it for the rear sight
thanks
