I should preface this with I'm mostly looking for something when going pig hunting and other predator control, I will be using NV so will be putting on a Steiner TOR Mini IR on it, so having a picatinny accessory rail underneath is a must. I shoot 10mm, 40S&W and 9mm currently. I've wondered should I go with 10mm for more stopping power or do most of you feel 9mm is just fine with the right bullets for the big piggies.
