One neat consequence of the P320's modular nature is that you can test the effects of very specific changes, like the shape of the new X-series grip module. Same trigger, same top end, only the frame is different. Or you can, for example, swap back and forth between the factory Sig lockwork and the Grayguns-tuned FCU while keeping the rest of the gun the same.

It's pretty interesting. I'm grinding the numbers, and they'll be in the Shooting Illustrated article.
