According to the FBI Student Training report on pistol ballistics. Knock down power is a myth. They prove it with the pendulum test and further prove it with Newton’s Law. For ever action there is an opposite and equal reaction. In order for you to knock me down with a bullet shot from your gun it would have to knock me down the opposite direction. I will further make my point: I have shot several 160+ lb deer running at or slightly away and towards me with my 338 Winchester Mag. 275 grain bullet over 2 times the velocity of a pistol with same weight bullet. No deer to date has stopped, flipped over or jumped up and or flew back as in the movies. They actually kept coming forward and or in some cases kept on running for a while. So if you think you can carry something in your pocket that is better than my Glock 26 9mm or my kel-teck 380 you got to prove it to me. I have carried a gun for over 25 years, all I want is a gun that I can hit with (first and foremost) And for you 40 s&w in a sub compact gun guys, go shoot double and triple taps once and you will see why most police dept including Brooklyn park will not allow off duty cops to carry glock 27. They can’t hit with follow up shot’s because of recoil. If you can’t hit with, it does not matter if you carry a 338 Mag! Next I want something I can hide and is light. If it is uncomfortable to carry and hide you will not carry it long term.
The French police have carried the .380 with great success and have proven its ranking as a man stopper.
If you want to argue this with me I want facts not myth. Most of you who carry will not shot enough not to be a threat to any one near who you shoot at. (most shoot less than half as much as police officers , and they miss 53%) So please do not get caught up in the I have to have knock down power trap. Get the gun you can shoot the best with,3 380’s in the chest is better than one hit and 2 misses in most bigger calibers. Multiple wound channels kill fastest. This is a fact more holes to bleed from.
If I told you I will give you $10,000 dollars to the best group at 21 feet would you use your Glock 27 40 S&W or my 22LR auto? Give some though to this.
