Default 9mm vs .40 s&w

OK, I chose 40 a long time ago over 9mm. At one point, everybody was saying 9mm doesn't have the stopping power. I can't help but think now 9 is a wuss caliber. HOWEVER, 9 tends to have WAY more capacity, everyone seems to say it's cheaper, and now people are saying 9 isn't that bad in the stopping Dept.

Anyone have any opinions on this? If there is another thread that discusses it, (a search didn't turn up any), let me know.

I don't think you searched hard enough. This has been discussed ad nauseum previously.

In a nutshell... take your pick. They are both effective rounds with proper training and practice.

9mm has come a long way in the past 10 years the slugs perform a lot better but you have to do your part too. I personally don't carry 9mm unless it's +P+ ammo or in a 357 Sig which uses 9mm diameter slugs.

step one: forget the myth of stopping power

step two: find a style of defensive handgun you find comfy in the largest caliber you can control, it should be near 100% reliable as possible

step three: practice until you are very fast and accurate and know the firearm inside and out.

stoppping power is a bullsht myth invented decades ago to trick people into favoring on gun over another.

Put a 9x19, .38 Super, .40S&W, 10mm Auto, and .45Auto next to each other and see which one you think is more effective.
Then look at power factor and which you think is more effective.
Then decide if you need to penetrate several layers of clothe, thus making almost all HPs ineffective.
Then, find a gun you like and whatever cartridge it takes, you will be able to find some effective ammunition for it (unless you drop below .380 Auto into .32 and .25 territory).
I can not imagine my ever needed more than 8 shots, so most of the guns like come in a large caliber that takes one in the chamber and 7-8 in the magazine.
I won't be in shoot-outs or gang attacks or surrounding my attacking savages. I can not imagine getting into a tactical situation that would require more than two 12-gauge buckshot loads and 8-9 .45 Auto rounds.
Rather than sweating this stuff, practice until you can hit center of mass at 5 yards from the hip and center of mass at 15 yards concentrating ONLY on the target. Then, you might actually HIT something--which is more than most bad guys and cops seem capable of.

well i have a xd 40, and am waiting for my sr9c. i used the beretta 92 in the military... personally i like the 40.. seems to leave a bigger hole in my targets.. and has made it around thru 3.75 inches of solid wood... i pulled out all my slugs from the 4th 1 inch board i was shooting. but 9mm ammo does seem to be a few bucks cheaper..... shot my friends 44 mag the other day.. i think that would win in a gunfight. lol.

Yeah, I don't think I searched enough, either......Those were the responses I was expecting, though. Sounds good.....Fortunately, the gun I like, the Beretta 90 Series, comes in both.

If you are not to far away, you can try a few of mine. 9x19, 10mm, .45acp

You know this based on what?

OP, All of them cause damage...the question is how much. I am a believer that a bigger caliber (on same category i.e. regular, magnum, etc.) will do more. Factor cost, recoil, accuracy, etc. and base your choice on that.

Myself, I prefer .40 cal but will not feel inadequately armed with 9mm especially when loaded with my favorite ammo (Federal HST and Winchester Ranger T).

The Beretta will offer good handling and performance for either round. I favor both 9mm and 45acp over 40sw, because I can put follow up shots on target faster with either. A Beretta 92/M9 will find its way back to the target very quickly, and in a defense situation that's a critical factor to consider.

If you shoot well and choose good ammunition (127gr +P+ Rangers or 147gr Fed HST for 9mm), it is highly unlikely that you'll ever find good cause to feel underpowered. But it's also highly unlikely that a 40sw in the same circumstances would fail to have enough capacity for your needs.

Or you could kill two birds with one stone and look at an XDm40, with 16+1 capacity and a frame size/shape that's not so far off the Beretta. It is a little plasticky though.
