Here's the one on my Zoli. Fits perfect and has a nice palm swell. If I had any complaint it would be that they didn't get the "finish" all the way inside the cavity where the PFS mechanism fits into. Other than that, it's fine.
I did have to file a little of the finish off the little "wings" that fit into the receiver on both sides. It was a little too tight at first, but once I did that, it fit perfectly.
