40s&w or 9mm
I was wondering what the better round is the 9mm or 40S&W any advantages or drawbacks?

Better round for what?
9mm, little recoil, less noise, good accuracy, underpowered (in my opinion)
.40s&w, more recoil, more noise, good accuracy, good power.0 -
They can be both be used in the same platform (size weapon). Prior to the (idiot) magazine restriction the 9 held more and that was the biggest selling point. Due to magazine restrictions this is no longer the case. Be it right or wrong, most law enforcement agencies have oppted for the 40. There is a bit more recoil (from equal size weapons), and most consider the 40 to put more 'stop' on target. But there is not a "drastic" differance in their terminal performance.
I personly prefer the 40 with 150-155 gr JHP. These are standard pressure loads. The 9 would require the +p or +p+ loads to equal the terminal performance of the 40. Therefore the muzzel blast and recoil would be close to the same. On the new mini guns the magazine cap may very a round or two.
If you do your part (put the bullet in the right place) and have an accurate and reliable weapon with good ammo either would be fine for self defence.[^]

I have never owned a 9mm but do own a 40s+w G22. I like the 40 for several reasons. It is accurate, has adequate power and is becoming more and more popular with LEO's so the prices are coming down on ammo. I still like the 45 better, though that may be due to the really sweet trigger of my Kimber. Ballistics are supposed to be similar between the 40s+w and the 45acp.

Thanks for the advice I just ordered a Sig 229 in 40 S&W I own a nine but wanted more knock down power with a decent mag capacity.I to own a 45acp and really like it but it can be a little bulky to carry.Hopefully the Sig 229 40 S&W will offer the best of both worlds Knock down power and concealability.
Thanks Again0 -
you want seriuos knockdown in a compact package, take a look at the 357sig balistics.
The way I see it,If YOUR rifle shot as well as YOU say,...we wouldn't need gunsmiths.0 -
well...now that he ordered the .40, all it takes is a barrel swap and he's got two guns in one.

I use both 9 and 40 in the Khar concealable, and the 40 does not present a problem with recoil, but does deliver a serious impact. Can't put my life on a 9mm when I have heard so many stories of people continuing on after being hit by it. I have seen films of the impact of a variety of calibers and the 40 makes a difference. I prefer the 155 grain myself. The heavier the bullet the heavier the recoil. I just started to reload with lead 180 gr and the kick is obviously increased. Much more enjoyable at 155 gr. The 40 does cost a bit more to reload, but its not a big deal. My Kahr is extremely accurate with both calibers and a variety of loads.

I own all .40 caliber handguns, all of the 9mm that I owned were fine guns but I prefer the .40 over the 9mm because of the knock down power of the heavier bullet. 0 -
Or, depending on which gun you are looking at - consider a 10mm. It is basically a .40 only is a little longer and more powerful. I know for my Glock 20 I can get a .40 barrel and also a .357 Sig barrel. Why settle for 2 guns in one when you can have 3 guns in one? [;)]
The recoil on the 10mm is a little stiffer than both the ones you mentioned, which is why I think it never gained widespread popularity. It has more velocity and energy than either the 9mm or the .40, and also the .45 as well. Factory loadings are nearly identical to the .357 mag and can be hotloaded to .41 mag levels.
Not saying get one, just saying you might want to check it out, depending on the firearm you choose, it might allow for other calibers later. I would shoot one first unless you can handle magnum caliber pistols without trouble. Just my 2cents worth.
Oh, about the 2 rounds you specifically asked about, most of the advantages and disadvantages have been listed. One I didn't see is the possibility of over-penetration. If you have kids in your house you might want to choose a lower powered round or maybe even a shotgun for home defense. They do make fragmentable ammo for either caliber too.
Good luck! (I personally think my signature says what we all need to know...)
It doesn't matter what you shoot, just shoot it well...0 -
The 40 is a good cartridge and I have several myself, the thing one must remember is: bullet placement and bullet configuration.
It doesn't matter if you shoot a 9mm or 45ACP if you can't hit the target where the it matters. Also the type of ammunition being used makes a difference in the results be it FMJ, HP, Glasers, Silvertips, Talon, etc...
Bigger is not always better.0
