The first 329 PD I bought was shortly after they came on the market. That gun was in the mid/upper $900’s. The second one bought early last year was close to $1100. both were purchased new. I’ve only seen two come up for sale locally in the last couple to three years. $900 or thereabouts was the asking price. It’s a gun you just don’t see very frequently on the secondary market (at least I don't).
With the recent edition the wood grips were changed up. Somewhat less bulky than previously(should conceal better with the rounded butt) with nicely cut checkering. I had no issue with the original wood grips as I liked the way they looked and size wasn't important since I carried it open in the back country. S&W also is using a new style rubber grip which totally encases the metal backstrap. that's bound to make a noticeable difference in comfort when pulling he trigger on full house loads.

I really like how the those grips feel, a lot. Hopefully they are ok for specials
