    Please become acquainted with physics and biology.
    I'm extremely well acquainted with both, thanks. The things you're saying are not math, science or physics. They're hear say and myth. The amount of damage from the diameter of the round relative to another is tiny from a pistol. The velocity is too slow to cause damage to tissues near by from the cavitation, and pretty much all the damage is from what the round actually hit. The actual difference between 9mm or .40 or 45 is splitting hairs. The difference is pretty much negligible.

    So shooting where there is no body armor isnt overcoming the problem body armor presents?
    If you're able to hit vital areas under whatever circumstances, then yay, but you guys sound like you all think you're John wick or some special ops guy that is going to be cool under pressure and there's always a clear opening for a clean shot with your ultra steady hands as your adrenaline rush courses through your veins. I wouldn't count on it as a sure thing.

    I have learned on thing for sure ............. a large percentage of members on this thread are experts on everything.
    I'm not an expert on anything, but I call bullshit where people dump it. A lot of this garbage is just regurgitated nonsense that has nothing to back it up. They've heard it and repeated it so many times they believe it.

    I wouldn't consider a Glock hitting where there's no body armor, penetrating/overcoming body armor. I'm aware of 5.7, I was only referring to the Glock statement.
    Oh and incase you missed the subtle nature of my comment, insert any handgun you wish where I put the word "glock".

    Point was you can spend much less and be just as effective.

    I’ve been eyeing a G22 the last couple of days. There are some really cheap LEO trade-ins that are pretty tempting. Could always swap to a 357SIG barrel or swap a G17 slide on if I wanted to.

    Don’t need a .40. Don’t not need a .40.

    To address the original thought, 40 became popular when 9mm ammo wasn't as effective as it is today and there was a real advantage to the 40 over the 9mm.

    The fact the 9mm is seemingly closing that gap due to modern ammo is why many are going back to it. There is no reason to put up with the increase in recoil.


    Along this line is the reason the 10mm is resurgent in popularity with some. There is a real difference in Preformance now between it and the other calibers for those wanting to put up with it. They are tKing Cape buffalo with it for christ sake. Lol

    I'm being realistic about it, Mr Wick. I didn't realize I was in the presence of so many elite operators and assassins... /Sarcasm

    Mr wick eh. Lol.
    So no?
    Is it shot placement.

    Caliber.

    Weight.

    Velocity.

    Platform.

    I've already explained it in previous posts, if you have actual questions feel free to ask for elaboration. It's not a single characteristic about a pistol round. The statements I've made are regarding the typical calibers used in handguns, not things like the smart ass responses about .22lr, etc ...

    Please read post #3 and explain your statement it to me.

    You have to know where things started

    The origional 9mm loads were 115lrn and some HP that didnt always perform well. By preform people are using the FBI testing protocols developed after the Miami shoot out.

    We got to the 40 after the FBI post mortem on the shootout. They determined specific preformance requirements in penetration and penetration after barriers were encountered. The 40 was a compromise because the 10mm was too much for many to shoot.

    Since that time alot of progress was made in 9mm projo's and powders to the point that 9mm 40 and 45acp preformed very close to each other in those tests, penetration and penetration after barriers. This started the massive transition in law enforcement back to 9mm.

    So while all 3 calibers benefited from work done to improve self defense ammo 9mm has made the most progress in those testing protocols.

    You didnt explain, really, what you did was you told several folks that they were wrong even seemingly contradicting your self regarding shot placement, if its important or not referencing bullet diameters and the ability to shoot under stress.
