Like I said I am a competition pistol shooter with mini trophies so I know what I am saying I agree with you completely,I like and have both -a DW Guardian in .45 and a sig p365 9mm for carry.The choice on which to carry depends upon where I am carrying and why for that day.I believe the ability to have both options covers more scenarios.Great info BTW. If I saw a bear close that wasn't moving, I'd get the spray out and slowly back off, and use it if he started coming my way. https://www.personaldefenseworld.com/2017/03/9mm-40-45-acp-stopping-power/ But to a victim or an attacker, what happens when an intruder gets hit by birdshot may be a lot different to 00. If you can hit with one and allways misswith the others , I think I would chose the one you can make the most hits with, just from my own exsperance , I had some mild steel targets out at my home we used to shoot at all day and almost every day with .38 spl, And 9 mm, then I bought a kimber1911 This is a 9mm Luger ballistics chart (external) generated using our ballistic trajectory calculator. When comparing the Glock compacts in both calibers, the 9MM was less bulky, lighter, and easier to conceal. The situation is now dissolved without any bystanders in the background getting injured. with your statement 9mm has less recoil. We already have an account registered for email address Unlike in a home defense situation, the ability to shoot through a wall, automobile, or various other objects in a combat scenario can be the difference between life and death. Be familiar! If he hits you, its going to hurt. Tanks, trucks, rifles, the UK's ability to actually fight a war was incredibly damaged and near unsurvivable had the Germans pressed an attack. Thats the meat eater .lol. Let me know in the comments below! Modern .45 acp is overkill against most targets (which isn't a bad thing in itself, but better to have the extra capacity if you don't really have to trade a significant reduction in lethality for it). This would most likely result in you firing at the assailant in a less accurate fashion as well as possibly harming others. 2. They are not an ideal carry gun, howyever. As the semi-automatic handgun gained traction in the late 60s and early 70s, so too did the 9mm. Locally we are seeing a lot of police involved shootings using 9mm, and they empty the clip almost every time. Both rounds are more than enough to put a guy down. Studies done on combat troops show similar hit ratios to these LEO stats. He further explained that smaller shooters found the 45 to be more accurate on follow up shots due to the reduced muzzle movement. Less recoil , good penetration, good follow up for stopping a robber etc. In theory the bear will advance into the spray mist and his breathing apparatus will suck in the irritant and it will get into his eyes and mouth. But lets not forget the same developments in HP ammo that allowed 9mm to catch up to .45 ACP FMJ also allowed .45 ACP HP to beef up. For instance, Hornady uses a 24 barrel to test and record muzzle velocities for their 223 ammo. 9mm can be a reasonable choice. Once you're done with your YouTube videos, come back when you get some real world experience with that one 9mm you've taken to the range once. Exactlyother than the special forces, army and specially trained police. This trumps expansion. Also the title of the article seems to contradict his conclusion that the extremes are seperated by a mere 10%. New developments not only improved the 9mm, modern 45ACP can make a 1 hole and 50% more energy delivered on target. After examining the gunshot wounds, the study ranked accuracy as follows for chest and head shots: .380 ACP (76%), 9mm (74%), .40 S&W (76%), .357 SIG (81%), .45 ACP (85%), and .44 Magnum (88%) (there was no information on 10mm). It was also made clear that the almost same effectiveness of 9mm compared to .40 S&W and .45 ACP was due to the high quality of 9mm ammunition available. This, unfortunately takes time to accomplish. The 9mm is easier to conceal but when I am on my Harley I like to carry the 45. I know better than that. The history they told me was that the military originally was using a 38 something or other, but some weird fanatical types just kept coming at them in one of our many obscure little wars. Wish you had more ammo brands like in the 45 acp test you did. In the majority of the states, anything more than 2 rounds down range puts in in the pin for excessive force! Another benefit is that both are bottleneck cartridges dramatically lowering the chance of a failure to feed malfunction, an issue with both the 9mm and .45. .45 ACP does have more advantages than stated in this article, namely that the .45 will not get deflected by bones nearly as bad as the 9mm (for example, pro bowlers, as they age, would rather stick with a 16lb ball and have less speed than drop to a 15lb ball and keep their speed high - the difference between a 15lb ball and a 16lb ball going through the pins is astonishing). . That's a big difference, and could be the difference between a heart shot and a lung shot. For example, American Eagle makes 9mm full-metal jacket rounds with 115-grain bullets and 147-grain bullets. If Im going for a fragmentation round, give me a .357 SIG from Liberty Civil defense at 2,300 FPS. What does "slow" mean? 9mm rarely reaches major (165PF) unless specially loaded and unsafe if you ask me. One of the main reasons why military personnel and many LEOs made the switch to 9mm handguns was because of the deeper bullet penetration. I also carry .357 Sig In the winter time for thicker clothing on my would be enemies. You don't want to let the wind blow it away and waste it if the bear isn't moving. Why is that? Im a big fan of the Colt 1911 45 with 7 and 8 round mags and have carry one cc for a few years. All the tellings of limited knowledge. My 1911 in 45 has little recoil barely if any more then a 9mm.

Everyone has their own confidence level and may believe what people tell them or what they read. It also delivers additional felt recoil and comes with slightly higher recoil velocity. The marines and FBI went to the 9 so women could qualify because only 1 in 10 can with a 45. though they cant come out and say so. One hit with a larger caliber is more debilitating than a smaller one. Also designated the 9mm Luger by SAAMI, and 9mm Luger by the CIP. A 45 will stop an attacker much quicker than a 9mm. The comfort level of a a Colt Lightweight Commander is on par with anything out there, and that design is older than any of us still alive. Measurements are the opposite of vague . A 124 grain plus P will not start dropping velocity until somewhere over 16 inches of barrel. This length ratio maximizes the projectile velocity. I think the recoil of 45 is way overblown. The debate over the 9mm and .45 ACP is one of the most heated conversations in the firearms community. My preference is for the .45 (partly due to the fact that though I've fired a 9mm, I don't own one but mainly through greater familiarity with the .45 & having a decent stock of ammunition for same) but I don't think a person would go wrong with the 9mm & for that matter (even though it wasn't included in the comparison) the .38.

Like clipped on the front of your backpack harness or belt, in a manner where it can quickly be retrieved and used. Do the math. Capacity is not an issue because, I live in the DPRC (Democratic Peoples Republic of California). I think there was a fundamental mistake about over penetration in this article.

Standard pressure .38 Special only produces 264 foot-pounds of force (147-grain bullet at 900 feet per second . Then again, if penetration through a bedroom door, heavy jacket, glass, etc your .45 won't make it to the target, so much to think about! Soul people go to hell. I don't think i would hesitate to use my ruger 1022 for home defense with modern rounds like stingers or velocitors the new browning rounds that go 1450 fps. Plus, I think the just plain weight of the 45 carries more "oomph".
