    For the folks that think that "bigger is better", how do you explain the performance of the 5.7x28. 40g at 1800+ fps from a pistol.
    Both speed and size are factors in any bullet. Also, bullet design is most likely also just as important. ( Fort Hood shootings, Mexician cartels, and Secret Service)
    Read at least two comparisons that rated the fn over .45acp, from respected sources.

    As much as I like the .45 for putting big holes in humans (never had to do that and hope I never do) there are other considerations. A big one is the fact that slow moving (relatively), large projectiles like the .45 ACP bullet won't penetrate things like a car door steel nearly as well as smaller, faster rounds. That's one area where the 9mm has it all over the .45. And in this modern world we live in being able to penetrate a car door might save your life some day.

    Then there's the .40 S&W. It will also penetrate car doors but it's bigger than the 9mm. People tend to think of it as a compromise round but I don't buy that. It's a round with it's own set of features. And with modern ammo it has most of the good features of the 9mm and the .45 ACP. No it isn't as big as a .45 round but if you can't shoot through that car door to get bullets where someone is hiding and shooting at you then you have a big disadvantage. So I bought myself a .40 and I've been carrying it in my car. BTW most of my confrontations with idiots have come in cars in my life. People think they can do stuff to you and then get away and for a long time they could. If you don't believe that ride a bicycle around a while and see what happens. Some people love slow moving targets on bikes and will throw things at you that could easily kill you. Trust me I know. Now we are faced with a large number of fellow citizens that can also have a gun legally in their car. You just don't know which ones might go off on you although the percentages are very, very low. But it's that 1 in a million chance we have to worry about. So I want something that will penetrate car door steel and another problem area, car windshield glass. The ammo I use in my .40 will penetrate both (Hornady Critical Duty) which gives me a big boost in my protection IMO.

    WOW ... As in most of what you just said it factually incorrect. Keep reading grasshopper.

    Loosely translated in this instance, it means I cannot envision a real-world self-defense scenario where I would be legally justified shooting through a car door. Back when I was a LEO, yes, but not as a civilian. Feel free to enlighten me with a plausible scenario.

    Expecting any handgun round to reliably penetrate a car door is, um, optimistic at best.

    I've seen the .357SIG as a solid go-to round for car door/windshield penetration but I haven't heard or seen where the 9mm has it all over the .45 in that aspect. I've seen 9mm rounds that have partially or completely come apart upon penetration. I've also read they're more apt to have a trajectory deflection due to lower mass contacting the inner door framework.

    As a .45 user, can you point me towards references that attest to the fact you stated above regarding the .45's lacking ability of penetration? I'm interested to see that.

    ETA: Just thought of something...Are you referring to a 9mm round fired from a 9mm handgun? Or the 9mm round fired from a .357SIG handgun? If the former, I disagree. If the latter, I agree. Not that I have a need to penetrate cars and doors at home. At work, that's another story...but I've got better calibers for that use.

    Since we are talking about penetration now, I did a test on this at work a while back. Wanted to see how bulletproof plain polycarbonate was. Started of with a 1/4" sheet which only stopped up to 32 ACP. Went to 1/2" which stopped 45 ACP but not 9mm. This was all with FMJ round nose bullets.

    It is all about shot placement with a caliber you are good with, For me that is 45, 357, or 9mm

    Training and practice trumps all.

    After a decent amount, you'll spend less time worrying about equipment. Might even understand better shot placement is more likely to happen when one trains and practices.

    I mentioned to my shooting buddy, after he said his annual hiking/camping trip in the N. Idaho panhandle had included being warned about black bear active in the area. He had taken along his Glock 19.
    He saiid he felt a bit under gunned. At the time we were driving back from the range. I told him I once read that Denmark puts two man Army teams on the Greenland Ice to census Polar Bears. They are armed with a .30-06 Bolt Action rifle and a Glock 20.(10MM Auto).

    A few weeks later, I got to shoot his new Glock 20. Nice manageable
    Rem. 180 gr. at 1,200 FPS. Heck I'm a 45 advocate ( 1911 & S&W 625( but that 10 is appealing. Oh, I also have an uber reliable and very accurate 9mm / CZ 75B - carry load is Double Tap +P but it's secondary
    to the 45s, but a cheaper range option
