    40 caliber versus 45 caliber for home defense?

    Are these two ammo's really about the same in neturalizing a BG?
    Will either one neturalize faster then the other?
    I know that eventually all calibers will have the BG bleed out (besides a 12 gauge shot-gun) but that takes a few minutes while the BG could be doing some serious damage to you!
    This ammo would be used for home defense!

    6 months ago my wife and I called the Police Dept. on 2 intruders trying to enter our home-so I am very aware of how crazy parts of society are getting!
    Does anyone have any street knowledge on what caliber ammo works the best?

    Many thank-You's for your thoughts!

    Both will do the job as well as a handgun round can be expected, provided you do your part and place the bullets in a vital area. Bottom line caliber matters less than placement. Most experts advocate 9mm or bigger for defense.
    Personally I use a .223/ caliber rifle for higher capacity , more accuracy.

    Sounds like there were no ill affects from the attempted break in, and for that I am glad.
    I have no first hand experience with .40 caliber performance/ballistics so I can't comment.
    I have seen the effects of the .45ACP though. For that reason I've accepted it as my choice of a personal defense round.

    I tend to think of this as driving a nail in a piece of wood and how many times you are willing to strike it in order to set it. Your selected tools are 12oz framing hammer, or 16oz framing hammer. Which do you think you'll have to swing less times?

    In order of priority: 1) what both of you shoot best (hits count), 2) magazine capacity.

    There are probably no definitive answers to your questions. My opinion is that either works well. I have both in my defensive arsenal. The VT shooter was very effective with "only" 9mm. One school of thought says that all pistol cartridges are equally weak compared to rifle cartridges.

    The link below alleges to answer your third question. Scroll down this loooong page for details on many different brands, sizes, and 1-stop ratings for most pistol cartridges.

    Its a personal choice. It seems to me that a bigger caliber heavier bullet should be able to do more damage. That's just the way it seems to me though...I'm no scientist.

    Just in the short time I've been a member here I've seen several threads almost identical to this... 357 Sig vs 40, 40 vs 45, 9mm vs 40, the list goes on...

    I think .40 SW or .45 ACP are both fine choices if you select good SD ammo, and PRACTICE! Shot placement > bullet size.

    Do you really think a BG gives a rat's bum if you're hitting him with a 230gr at 900fps or a or a 180gr at 1050fps? Nope.
    If you use proven self defense ammo, and your shot placement is decent, I doubt anyone but a coroner will be able to tell the difference

    My input: Use whichever you can control better. Since you should be practicing a lot, you might also consider going with whichever one is more economical.

    Peace,

    For home defense I would say neither.

    12 Gauge pump.

    You should still have a .40 or a .45 which ever one you choose, but thats to fight your way back to the shotgun you should have never put down in the first place.

    I have both calbers. I shoot the .45 (1911) better than I do the .40. I prefer the Magtech Guardian Gold, 185 gr +P JHP for my 1911. It goes fast - 1148 fps and puts out an amazing 540 # muzzle energy. My prefered load for my .40 is also Magtech Guardian Gold 155 gr JHP. This yields a whopping 500# muzzle energy. Both calibers expand very well. Compare these specs to other brands and I think you will be surprised.

    #1: Make sure your gun shoots your chosen ammo WITHOUT ISSUES! This will take several trips to the range with several different boxes of various ammo.
    #2: Be able to accurately shoot whichever one you choose
    #3: PRACTICE, PRACTICE, PRACTICE

    Like so many have said before, it's simply a personal choice. Both calibers will preform the duty of home defense. Personally i choose the .45.

    What do you shoot best? If it's for home defense, then size does not matter. So if I look at a full size SIG P220 with a magazine capacity of 8+1 rounds, compared to a full size SIG P226 with a magazine capacity in .40S&W of 12+1 rounds.

    With no pressure and in an ideal situation you should be able to stop anyone with one or two shoots with either a .45 or .40. Under stress you will probably miss a couple of shoots or possibly not hit center mass. How many will it take to take the BG down?

    Personally, I like the idea of having a few extra shoots even if I don't use them without having to reload.
    Be Observant and Be Safe.

    Current: S&W 442, Springfield XD9sc, XDm9, and Glock G26, G19, G23C,
    and SIG P226-40 TT, and Ruger GP-100, and Beretta 92FS
    Former: Taurus 92SS, SIG P220 TT, S&W 360, SIG P239-40, Ruger 22/45 MKII

    bigger is always better, I say .45... but mostly I would go with a 12ga. I can only imagine the blast on a target 10 foot away. Imagining this is mighty impressive, imagine the wound channel.
