Not my gun in the picture, but I've got one identical to it. Same Nill grips and Gemtech MultiMount. I went with Gemtech because it was the lightest and one of the smallest suppressors that my local class III gun shop carried. The Nill grips are worth every penny if you ask me. I was a big fan of the rubber grips that game with the gun as well. However, after trying out the Nill grips, I didn't think twice about putting the rubber grips back on.
I did business directly with the company in Germany. I've got to say, their customer service is amazing! I was confused because some of their pictures were outdated on their website, and they explained everything that I wanted to know to me. The grips in the picture is the model number CZ0358, which I got for $120. That was when the US dollar was weaker than it is today. Now you can get a pair for $105.
I go to the shooting range a good bit, and it's become common for people to ask me what gun I have every time I go. You don't see that many CZs in the States. It seems all I see at the range nowadays are Glocks and Springfield XDs. I'm happy with my P-01.
