I've had several sets and love them.
I prefer the VZ 320s, they didn't "dig in" as much as my Gatorbacks, and I also have a set on my Hi Power that I really like.
I kept the 320s on my Baer until I got some red/black G10 Hornded Lizard Monkey Grips for it...I think I need to put my VZ 320s on my Springer.
I've been wanting some of the VZ G10 Operators, but that's going to have to wait a while I think.
I'll post some pics shortly.
Here were my black/gray VZ 320s on my Kimber PRO, the only thing I didn't like about them was that they looked like crap when they got damp from sweat or oil deposits.
Here's my Springer w/ black paper micarta standard thickness gatorbacks.
Here's Lima's Kimber wearing the slim gatorbacks. **Note that there's no grip material over the plunger tube**
Here's my black paper 320s on my Baer.
Here's my ball cut VZ Hi Power grips.
Ok, last one...I think
My Davidson's Monkey Grips, red/black Horned Lizards on the TRS.
