A good suggestion with one caveat. The older guns have 1/10" wide ramp sights. I've reached the point where seeing those has become difficult. The more recent guns have much better sights. I prefer the older guns for their build quality and case hardened parts instead of MIM, but my two primary carry J frames are a 342 Ti and a 642 Pro. My shooting J frame is a 640 Pro with what are arguably the best factory J frame sights of them all.
