I bet they're expensive!
They were in the end. but Its the shipping and export tax that really impacts the cost. I felt the grips were quite reasonable at $95 and the 2extra mags only came to $52. Shipping and taxes flushed out at approx $70. (While certainly inflated..really not that big of a deal in the scheme of things)
The shipping/tax was a bit irritating but they were not available anywhere else. Even if CZ-US had them, they don't ship to Canada.
Not a big fan of the stock wood grips and I know I will love these on my blued 97.
