Shot placement is key. Neither caliber is a magic one shot stopper. Due to increased mag capacity's , the 9mm will keep you in the fight longer. We are talking about the FBI, in the US. Not whats legal in Canada, so get it right.
10mm is, and was the reason why first they switched to that round after the Miami shooting incident. The FBI might have problems with the 9mm (not penetrating barriers, car windshields and doors) and they might be back full circle on this debate.
Supposedly .357 sig is a one shot stopper, I predict that is the way the FBI will go after they re-relize that 9mm is not good enough.





























The .40 S&W is not going anywhere. I bought a G22 and a 40-9 conversion barrel. Like the idea that I can shoot .40 and 9 from the same gun. Like the snappiness of the .40 and the 9 for cheaper ammo.
