I've been reading a little about both of them and I really like the way they look. I'll probably only use it for HD and plinking. Im pretty set on buying either one of these or a Ruger p89. The grip on the 39 looks very comfortable, I figure it can't be any worse than my G19. One thing that has confused me a little is the naming of all of them. I know the 39 corresponds with the 639 and the 59 with the 659, but are there any others? I'd like to know the different models and differences in them. Also, are there specific points of wear I should look out for? Any help is appreciated. I just want to learn a little more about them before I hit the gun show next weekend.
