I was looking into getting a set of night sights for my XD40. I wanted TFO's but don't want to deal with melting them. So I guess its either trijicons or meprolights. The trijicons are kinda pricy compared to the meprolights and I have herd the meprolights are just as good. Does anybody know what the correct meprolight part number is. I just want sights same as factory no higher just night sights. Most shops don't know the sig sights work on the xd's. Thanks for the help guys.
