Has anybody tried VZ’s “ivory” colored 320 or Tactical Diamond grips on their K/L or even N frame? Wondering how they look on blued guns and how well they hold up to wear and resist discoloration.

Never heard of this company. Are their grips plastic? Do they resemble real ivory?

VZ makes good grips. Have sets on two N frames, Kimber Micro 9, and my 3" 686+ Talo. Pretty sure most, if not all, of their grips are G10 material.

VZ is very well known among shooters of semi auto's. Their most popular grips are G10 based on what I've seen. However they do make grips from other materials also. If I'm not mistaken they also make the G10 grips for Wilson Combat and maybe Hogue. I have a set of their grips on my Beretta and really like them. I have not seen any of their ivory(ish) grips in person but I'm hoping someone here may post some pics. I have a M27 that I would like to try a set on but only if they don't look like the plastic grips that came on my toy guns as a kid.

You've never heard of VZ? They've been making grips out of mostly G10 for a decade or more by now. Very popular with the 1911, CZ, and Beretta crowds.

OP, I've been eyeing a set as well. Just haven't pulled the trigger for one reason or another.

They’re 20% off right now which is what has me looking

I have a set on my model 60. I think the color I have is called zebra. IMHO they look good on blue or stainless. Solid white doesn't appeal to me in the least. IMHO, if you're not George Patton then they'll make it look like a pimp's gun. But I guess that's why life has choices. I like the grips but I haven't had them long enough to give a proper review or recommendation.

What price range are these in?

If they don't closely resemble real vory, I suspect they'll fare little better than the white "tuskoid" that S&W tried, or similar white Fitz or Franzite.

To be honest, I believe ivory (faux or otherwise) look best on stainless or nickel plated handguns.

Grip makers seem to think that ivory is off-white. Real ivory is pretty darn white. Think, piano keys. I do admit that a little color does help though.
