To be completely honest, I have never once in my decades of CZ ownership and promotion, ever referred to them by SKU. Is P-10C FDE, first gen, transitional, or second gen.
The easiest way is to see what CZ-USA lists on the website - if that number isn't the newest one, then it isn't the gen 2. My FDE is actually Gen 1, one of the very first ones imported, about 3,000 rounds though it and running in great shape.
