The very first CZ I rented was a 75 in 40. Liked it so much I got the 9mm version and kept that for nearly ten years.
If you just plan to plink and target shoot, get the 9mm. Ammo is cheaper and recoil less. If you even remotely plan to carry at some point consider the P01. It does everything the 75 can, but lighter and has better controls.
But agree about hog hunting, wouldn't use either caliber for that purpose.
