Those are beautiful.
I run the vz extra checkered grips on many of my revolvers, including 44 magnums, and they are simply outstanding. I would prefer nice wood grips or stag, and have both, but the vz grips do a better job. Jason Burton prefers them, and is the guy who convinced me to give them a try. Which shouldn't have been too hard a sell, since I use vz grips on my serious 1911 now for over 10 years.
