What caliber do you prefer and why??

I carry a .40, just because that's what I bought at the time. I've shot 9mm and can't tell the diff on the recoil. I like the punch the .40 has. 9mm would be a little cheaper to shoot but I still prefer the .40

Both are going to do what you want them to do. I have had a little bit of a shift and had .40 for just about all my carry guns. I had .40 because that was what I had in Law Enforcement, but have been making a shift to the 9 myself because the differences between the damage of a .40 and a 9 is almost non-existent for most people.

Medical Examiners have looked at bodies and could not tell the difference in the wound cavities of 9-40-45 and were not able to tell until they found the round itself. I have gone to carrying more 9 because I have a little bit higher capacity, it is cheaper to shoot, the recoil is not as snappy/sharp and I can get rounds down range just a little bit faster because the split is just a little bit less.

Both are great rounds and you won't do wrong with either one. .40 has more penetration power but I have no problem with trusting modern 9mm hollow points to do what they need to do. Most of us do not need to shoot through barriers like car doors in our everyday carry scenarios. You will have people that say one is better than the other but with the advances in round design you are going to be equally effective with either.

It's 6 of one, half a dozen of the other. If you have to use it, nobody will be able to tell the difference anyhow if you put the shots where they need to go.

Go with what YOU find that YOU can shoot the best and are the most comfortable and confident in using. There is no magic bullet, brand or model gun that is the best. There is only a bullet, brand and model of gun that works best for an individual.

9mm because I can find it anywhere in the world. I used to take a 9mm and a .45 with me overseas. I could hardly ever find .45 and .40 is nearly non-existent outside the US. I carry a sub-compact 9mm and I am very accurate including instinct shooting with it. Too comfortable and confident in it to change.

i carry a .40 just beacuse i like the power behind the round and with the right ammo there is alot of it. 9mm is no joke, to me thats the lowest id carry as a primary gun, but all of my hand guns are .40 so...

use what works and shoots the best for you, after all its about shot placement anyway, if you do your job the round will do its.

It makes no difference. The best rounds in either caliber are about the same. I have both, and would carry either one with the right ammo.

Which one ever one feel's the most comfortable and you have confidence in to protect you and your loved ones life. I have carrird the 45ACP for over 30 years then had surgery on my shoulders and tried the 40 S&W with same results to shoulder pain, I now carry the 9mm with confidence and my training in shot placement. This has little to no pain in the shoulders and it is very cost effective to feed.

I cannot tell you which caliber is the best choice for you, only you can make that decision. Although, find a range that rents firearms and try out the ones that you think you may want to purchace.

There are plenty of tests to support the point of view that "bigger is better." Gelatin and statisical data is touted all over the place. (Blah, blah, blah type stuff.) However, I have to believe, if you make the first one count the rest doesn't matter as much. The question remains, what gun do you shoot the best?

As a side note. I did watch a video recently of an attempted robbery where the BG took two 45 rounds and staggered away. It didn't knock him down or take him off his feet. He staggered about 10 feet and went down. I don't see that 9mm or 40 is going to matter that much. Perhaps more capacity with the 9mm than the others, but you still have to make solid hits.

Anyone worth shooting, is worth shooting twice. Ammo is cheap, life is expensive.

Well placed shots from a 9mm will be just as effective as well placed shot from a 40,45,380,etc.

If you don't want to kill anyone then shoot them in the pelvis. They'll stop.

As stated above, either caliber is effective with proper shot placement. That being said, I limit all my carry guns to 9mm & .38+p for a couple reasons. 1)I only need to stock two calibers of ammo (in quantity, anyway). 2)These two calibers give me a lot of versatility in my carry options. I can carry my full size S&W if I think I need hi-capacity. I can carry my PF-9 if I really need deep conceal-ability. And if I require a BUG, my Taurus 85 will slip into my pocket. I'm not saying this is right for every one. it just seems right for me.

As indicated in previous posts, there's not much difference between the two rounds. The deciding factor will probably be the gun you're most comfortable with.

Go with what YOU can handel without any problems. I have carried some type of handgun for over 45 year's and still do but now I carry a .380 Walther with Speer Gold Dot Hollow Points and I am confident in my ability to take out any threat that should come up and so is my wife with her Walther .380. I carry the Walther because of Medical reasons and that I can't take the higher recoil of either the 9 M.M. or the .40 Cal. with my pain sensitive hands. Altho I own weapons of both calibers and will shoot them from time to time.

I also have a Walther PPK 380. It is the old styje and was wondering was yours the same. They call it the "James Bond Gun"

I have both 9mm and .40 s&w. I like both calibers and cannot tell a lot of difference in recoil. Like others have said, the 9mm is cheaper and probably more readily available.
I shoot a Glock 19 and a SR 40 C. They are both sweet shooters. I do use the 9mm more, due to the price, but I feel either is a good choice. Still you need to shoot both and make your own decision as to which you prefer.

No they are not alike at all. The PK380 is a little bit bigger and has an all polymer frame and a much better hand fit. Bigger sights and fully ambidextrious for both the mag. release and the operation of the safety. It is also a 9 shot weapon.
I traded in the Walther PPK/S .380 that I had gotten for my wife and got her a PK380 a few years ago. Yes I took a loss on the trade but as she is more then happy with the PK380 I don't care.
The only problem that I have with this weapon is that it only comes with one mag. and I had to put out almost $80.00 too get her and myself each a spare mag.

A hit with a .22 does more damage than a miss with a hand grenade.
