Is 40S&W any better than 9mm?

    Well i was talking to my brother about this last night. He loves my Hi Power but went on and on about the 9mm. He is a .45 fan. Now I think 9mm will do the job fine. Too many military units and police have used the 9mm for a long time. I dont think its as good as all .45's but I do think its good enough with the right ammo.
    Now my bro wants a Glock .40 for carry. He loves his 1911 but it gets damn heavy he said. Anyway he was saying the .40 is better than the 9mm. Bigger sectional density and a heaveir bullet going fast. Is there any truth to this? My bro knows a lot about guns. He says all handguns pretty much stink for stopping people. So he said why use 9mm when you can shoot something bigger. Well settle this for me so I can be right:D

    He's right!

    Grrr...sure to be a lively topic. I'm going to say that your brother is right...

    As far as as all handguns pretty much stinking at stopping people.

    That being said, I have my own philosophy about bullets and caliber, and it pretty much ignores any of those mathamatical 'stopping formulas'. All PFM as far as I am concerned.

    What I want in my gun is the largest caliber I can handle in a given platform, and the heaviest bullet in that cailber. That means that right now, I am using 180gr Golden Sabers in my .40, even though the lighter ones(165gr?) are faster, and supposedly have more energy.

    Tell him to get a Hi-Power in .40 S&W. Optionally, he can get a .357 SIG barrel for it.

    .40S&W is a GREAT all around round------if your'e using a good gun.

    Better? I wouldn't say better, just another option. I would say tho, modern defensive ammo is effective in 9, 40, & 45. Shoot the one you're most confident & comfortable shooting.

    Ballistically, a heavier, larger bullet travelling at the same velocites is "better".

    But, is the feed reliability better?
    Is the accuracy better?
    Are the recoil characteristics better?
    Is the price better?

    I would say no to the last 4.

    Yes. ;)


    This thread should get interesting...

    If your brother likes the 1911 but thinks it is to heavy and is going with a GLOCK why not show him a Springfield XD. These have the same grip angle as the 1911 and grip safety but are much lighter. The XD is available in .40 and 9mm and is cheaper than the GLOCK or 1911. Just my thoughts.

    At what?:rolleyes:

    If you shoot well with a 9mm, but not with a .40 S&W, then the 9mm is better.

    Use what you like.

    You're generally going to get what people carry as opposed to how effective they actually are.

    I've shot 45ACP in 1911 for the bulk of my shooting career. I can control it, I'm comfortable with it and I don't fear recoil. I agree that the 1911 gets pretty heavy. I went through this and ended up carrying only my P32 (which was supposed to be a backup gun, not a primary) and leaving the 1911 at home. I wanted something lighter weight and smaller than the 1911 so after trying out a lot of guns including buying several, I ended up with a Kahr P9 Covert. It weighs 15 oz, only 3/4 what the Glock 26/27 weigh and significanly smaller in every dimension esp width.

    I went with the 9mm version because I believe that, while 45ACP Rangers and Gold Dots are my choice in defensive loads, that any round 9mm and up, are very effective if you use the best load available and place your shot properly. What I wonder, is why if he's a fan of the 45ACP and is getting a Glock, why not go for the G30 or G36? Or even the G29 in 10mm? Very similar package to the G23 or 27 that he's probably looking at but considerably more energy if he's a believer in energy equaling stopping power.

    The .40s&w is better than the 9mm, but not the .45acp, unless capacity is your primary concern, in which case issues of competence begin to drift into the equation. :)

    IMHO- If you carry a heavy JHP in 9mm,.40,or.45 in Golddot or RangerT, then you are as well armed as you can be with a handgun.

    The .40 S&W is better than the 9mm for defensive purposes.

    Sure the 9mm is good enough with a couple of rounds (Corbon 115 and any of the LEO only +p+ loads) but the .40 is even better with MANY commonly available (read WalMart) loads in 155 and 165 weights.

    The 9mm is only a decent manstopper when it does it's .357 Magnum imitation with +p and +p+ loads.

    I know there will be many that disagree but I do believe in Evan Marshall's stats. He has a very large database of actual shootings. I don't see how people can argue with that.

    Incidentally you guys ever notice that while Evan Marshall is a great and knowledgable gun scribe his website forum sucks total ***! He only allows you to post "pre-approved links". :scrutiny:

    See the whole sordid story on my website (link in sig).

    DonGlock26- the 180 weight .40s have the crappiest record for stopping power of any of the various jhps in the caliber. Same with the 147 grain 9mm.

    This "manstopper" bullet is a bunch of bollocks. It depends entirely on shot placement and how determined someone is to get at you. I'll take my higher capacity, cheaper to shoot, waterproofed primer (NATO) :D, more reliable feeding, better penetrating, longer effective range 9mm over a .40 anyday.

    I wouldn't mind it if somebody would make a .357 SIG barrel for a .40 Hi-Power though :(

    Sure, the 40 S&W is better than the 9mm, and the 45 ACP is better than either one. Now that is sure to start a flame war!!!:D But nothing beats a 20 megaton nuke for putting down a mugger.:what:

    Seriously, shot placement is very important. If you can shoot a 9 accurately and quickly, but can't hit the broadside of a barn from inside the barn with a 40, then the 9 is the better round, at least for you.

    The question is very general.. let me see if I can narrow it down a bit...

    1. Terminal performance in ballistics gel: .40 S&W over 9mm.
    2. Terminal performance in human tissue: 9mm has established itself worldwide as a NATO handgun and submachine gun round.
    3. One-shot stopping power: Not Applicable. This is a myth!!
    4. Higher chamber pressures resulting in higher probabilty of a ruptured chamber: .40 S&W over 9mm.
    5. Harsher recoil, louder noise, bigger bullet, more machisimo: .40 S&W over 9mm.
    6. Slower follow-up shots: .40 S&W over 9mm.
    7. More accurate round: depends on you!!!

    At the end of all this what do we have!! IT DEPENDS ON YOU!!-YOUR LIKES, PREFERENCES AND BELIEFS:what:

    Here endeth the debate (yeah, right!):rolleyes:

    And what the hell does the above have to do with self-defense on the street????????????

    You do not want that kinda penetration on the street much less in your home.

    Then why change to a .40? He should get himself a lighter 1911. Maybe smaller too, such as a Kimber Ultra CDP or one of the new Springfields. If he's like me and a 1911 fan, he'll end up getting one to carry comfortably anyway, he just won't be happy til he does. Sure I've got many carry weapons, in different calibers, but none that I like as well as my CDP. And yes, one is a 9mm, which I like very much. I don't own a .40 and I doubt if I ever will. Never saw a need for it, as I own a 10mm. Now I wouldn't mind getting another one of those. Maybe a Glock 20? :D
