Simonich Knives has been the official distributor of Gunner Grips for at least 5 years now. They've actually stopped distributing them as of early 2011, and the only Gunner Grips available on the market are of a different production design. The material even feels different.
Note how the indent "pockets" look between the two versions:
Original:
New:
The old ones were rounder, and more oval shaped. The new ones are more of a cross checked diamond pattern. This results in very sharp peaks that, while was more tactile, I personally don't like the feel of.
I'd originally purchased mine directly from Simonich here:

However, all purchasing info now directs the buyer to VZ. When I'd contacted the sales reps early last year, they'd also turned me over to VZ, and said that the transition was new at the time.
I ended up buying a pair from TADGear (who no longer carries them), and they were the original style.
If you keep your eyes peeled, used original ones (or even sometimes unused ones) will pop up from time to time on gun forums (and even sometimes airsoft forums.)
