I don't own any N prefix N-frames and gravitate toward prewar, transitional, and post-war S-prefix examples with diamond magnas and target stocks. That's my thing. I have but two examples from the 1960's, a rare Model 21 and a 4" Model 28-2 shooter. The rest of my N-frames are 5-screw and a mix of stainless and blue N-frames made 1984-2008, mostly shooters.
Lately I like the early-mid 1990's N-frames and am particularly fond of the 29-5 and -6, and 629-2E, -3 and -4. Yeah, these aren't P+R or especially collectible, but they are pre-MIM, pre-lock, with tight throats, and have all the endurance updates. These are well made superior firearms, IMO, from a practical standpoint.
Here's a couple "classic" N-frames:
