Very general question. I'm sure that someone here is going to give you hell for not stating what you are gonna use the gun for. CCW, duty weapon, home defense, Zombie Apocalypse? What size gun are you looking to get?

Anyhow. Despite what some will tell you in, 9mm is a great round. It's been around for a while, so it's easy to find and comparitivly cheap. Lot's of penetration. Some consider it the "minimum" for a self-defense round. However, it is not a gun only fit for Sissys and Girls. You'll hear lots of folks tell you about all the "issues" the military has had with the 9mm round. Just remember that the military is restricted to using FMJ ammo.

40cal is great too lot's of LEO's use it. Very popular, not too expensive. Bigger round, so 40 cal guns usually hold less rounds than similar 9mm's. Some folks don't like the recoil of the 40cal, but I've never had an issue with it.

Both are great rounds, in fact they are two of THE great rounds avaliable today. Just depends what you want. There are lots of other differences, but i'm sure others will chime in with those. Just so you are ready, someone is going to get on here and tell you that they both suck, and that you need to get a 50AE, or such.

As a LEO I carry a Glock in 40S&W on duty and off. I also have other handguns chambered in 9mm and 45acp. The best round for you will depend on what your shooting ability is and what your requirments of the round will be. I have no complaints with either round and both are good personal protection rounds. A high quality carry round and having the ability to shoot accuratly even under stress is more important.

Honestly they're both more than capable rounds, especially when you use modern defensive ammo. I prefer the 9mm for capacity and lower recoil and muzzle flip. Lower recoil and muzzle rise means faster (or easier to become faster at) follow up shots. Also, the 9mm will have slightly increased capacity when compared to a similar gun in .40.

A plus to the .40 guns is that most guns can also shoot .357 Sig and 9mm if you buy conversion barrels. .357 Sig and .40 use the same mags, while you'll need new mags if you want to use 9mm. A more minor point is that I have heard anecdotal (read: unconfirmed) information that using a .40 cal extractor isn't good for shooting 9mm, but I don't know how truthful that is. If you decide to go this route, you may want to do a bit more research on that.

Just don't make the mistake of putting 9mm in a gun with a .40 cal barrel. Talked to a guy a few weeks ago at my LGS who swore up and down that he had a M&P that would shoot both 9mm and .40 out of the same barrel and do just fine

If you're going with a Glock, I would recommend the 19. I think the 17 is a tad bit big to conceal, though I had no intentions of concealing mine, so I went with the 17 and love it. Though I would contend that Sigs are superior!

Go with the 9mm, it is definitely better than the 40.

No wait, go with the 40, it is definitely better than the 9mm.



Seriously... do we really want to feed this 12 year old troll?

Move along...move along. There's nothing to see here.

Physically impossible. Ignore people that say these kinds of things.

whichever caliber you can shoot accurately and afford to practice with regularly.

Is it a full moon? I think I see a troll and he's already reeled in a few. Come on guys, go back and read the original post, all of it. Don't take the bait.

Oh yeah, I know. I just thought I'd mention it so the OP doesn't try it himself on the recommendation of some gun shop commando and end up looking like a fool at the range

If you feed the trolls it just encourages them.

If you believe that, why does caliber matter?

Good lord

Fellas, the OP is clearly just trying to jerk our collective chain.

Unsuccessful troll is unsuccessful...

 

[trex1310]

I don't like either one. I like the .41 long Colt. My custom Jennings
with 7.5 inch barrel is already chambered for it.



This post is as full of crap as the original.

 

[Tomcat47]

Was that one of those S&W MP 940's or was it a 409??

Man I want one of those!

 

[Gator 23]

9mm

 

[kgpcr]

.40 makes a bigger hole

 

[cfullgraf]

The one you hit the target better is the best.

Like real estate, it is all about location, location, location.

Glocks are not the best pistol. The best pistol is well known to be the Desert Eagle. I suggest one in .44. It is accurate, reliable, and easy to conceal. Perfect for home defense or carry. I personally feel that the gold plated version adds come class to an already classy gun.

If not that then the Taurus Judge is a good second choice. .410 is known to be a devastating round, especially when fired out of a 6" barrel. You will have a 3' wide cone of death in front of you after firing, enough to disable several intruders at once, even if they are armored. I have heard rumors of 5 intruders who faced "judgment" taken down in with 2 rounds. I guess that verdict was guilty!

Being serious, I think the account holder had a roommate happen on his computer and decided to mess around with it. His other posts are pretty normal.

 

[Geckgo]

cut down a barret to pistol length, get all the ATF forms first. THAT is a MAN's gun.

 

[David E]

If you need to ask, then the answer for YOU is 9mm

 

[Jed Carter]

Better for what? Pistols as a manstopper will most likely take more than one round to stop a threat. Might as well save the cash, and use 9mm, I have a G35 Glock in .40, it is the only .40 I own and is used in Limited, Limited10 divisions in USPSA matches. For defense I use either a 9mm or .45ACP
