Everyone on the Internet knows that 9MM is just as good as .40 or 357 Sig (terminal-ballistically speaking)

Everyone not on the Internet knows that 9MM is just as good as .40 or 357 Sig

Even I know that 9MM is just as good as .40 or 357 Sig



I just don't believe it. Razz


And, where will we go from here?

Which is the way that's clear?

Claiming to know something and truly believing it is a problem for many people about many things.

I myself try to avoid claiming to know things that I don’t believe, and I don’t believe that less power is as useful as more power when work (e.g., terminal ballistics) needs to be done. I just don’t try to change any minds because as I often state, if I am ever shot I hope it is by someone who believes less power is just as good as more power. Smile

I carry from weakest to most powerful. 32ACP, KelTec when I'm in a weapon prohibited area, it's not illegal, but you need to be low key, .Beretta model 84BB. 380ACP, .38 Special in a J frame, Ruger SP101 .357 magnum, but I carry .38 Special in it most of the time, or my Smith & Wesson model 10 M&P, just love that gun. Then 9X18MM Makarov, I have a East Germany Makarov and a CZ 82 in that caliber, I usually carry then walking the pups, for coyote protection, but for shitbag protection.

My everyday carry is a GLOCK 22 .40S&W. But I carry a GLOCK 17 9X19mm, HK P7, SIG P6, SIG P220 .45ACP, Beretta model 96 .40S&W. I also carry a 3" barrel Ruger GP100 sometimes.

Now this is anecdotal. I have put down seven (7) deer struck by vehicles.

Two with 9X19mm, two with. 40S&W, two with .45ACP and one with. 357 Magnum.

All to the head, the .357 Magnum was like the hammer of Thor. The .40S&W was almost like the .357 Magnum. The 9X19mm was very effective, and the .45ACP with one deer took two shots, the other did the job, but wasn't as effective as the 9X19MM.

But, I was carrying what I believe wasn't the best load for the .45ACP, not the shittest, but not a Gold Dot, Federal HST. It was Remington Golden Sabers, not bad, not the best.


I carry whatever handgun that is the best fit, usually with the best ammunition for that caliber and hope that I will NEVER have to use it to save me or someone else!

But 7 out 10 times you will find me carrying my GLOCK 22 .40S&W because I believe it has the best power, to capacity, size, to weight ratio out there, and I can shoot it almost as fast as my GLOCK 17 9X19MM pistol.

I may be slightly more accurate with my Beretta 96 .40S&W, but it's 10+1 bigger and heavier, I might be a touch more accurate with the SIG P220, but it's 8+1 heavier, the same with the SIG P6 except for weight. The HK P7 well, it is a total tack driver, but heavy for it's size, and 8+1.


I just want a reliable, accurate, handgun that I can trust..32ACP, .380ACP, 9X18MM, 9X19MM,.40S&W,.45ACP,.357 Magnum. I don't care. Fair ammo, and skill is the key!

Pick whatever you shoot best and load it with quality ammunition and forget about it except for training.

Many years ago at the Langlitz store I bought a high quality leather jacket. Jacket comes with a built in gun pocket. Salesman asked me if I wanted the pocket "tailored" to a particular handgun or a more general sized pocket that would acommadate a variety of handguns. I chose the latter and the salesman said "then you can choose a gun depending on how you think your day will go. You might even choose to just carry a paperback book." Never know with certainty how my day will go but I do make a reasonable assumption based on city vs. rural and what anti-gun obstackles I potentially will face. Caliber factors into the choice, ranges form 32acp to 10mm.

Kinda like a deer rifle, cartridge or particular hunting bullet. I like to talk ballistics, rifles & cartridges as much as anyone. When it comes to a cartridge for deer hunting, most anyone should be able to rattle off 30+ very ideal choices.

Some then depends on how one hunts, an Alabama bean field or maybe that cedar swamp in Maine.

But beyond that, the biggie is bullet placement. That 100 grain 243 gameking in the vitals is so much better that a 30-06 in the butt.
