Of the nearly 250 million guns owned by Americans at that time, somewhere between 40 and 50 million of them were handguns. What i find interesting is that so many people have so much to say and they have never been in actual shoot out. When a handgun is bought for personal protection, whether in the home or on the street, its purpose is the application of deadly force to protect your own life, the lives of others, and to prevent serious physical harm. at 2,690 feet per second, and slows to 840 feet per second at 500 yards. Theres not the penetration of a 9, because the mass of energy is transferred suddenly to the body in impact. The amount of energy a bullet radiates into a target is determined by a simple formula taught in high school: Its the product of one half the projectiles mass times the square of the velocity. Anyway great comments to all. To me the rest dont count. I can not remember a single specific instance of someone shot with JHP, where I knew for a fact at the time what I was looking at. Everywhere else, you have only a chance of incapacitating your target. Everything from grip, shooting stance, limp wrist-ing and recoil spring pressure was examined. Whats more, a temporary cavity measures volume that has been stretched, not volume that has been destroyed. Our only requirement is that you give Ammo.com appropriate credit by linking to the original article. The will to live and fight varies from person-to-person. There are a number of factors involved, including physical, psychological and physiological, but human bodies are much more durable than is commonly believed. We put our money behind the 9mm round fired by an extremely well-trained marksman carrying a Glock 19, Mannweiler told Marine Corps Times. I will never personally take a life if I have the chance to stop someone with a non lethal GSW. When all else fails, when the rounds fail to stop the bad guy, then you need time on your side. Only high-velocity rounds (those with an impact velocity of 2,000 feet per second or more) with soft or hollow points reliably offer fragmentation. While psychological factors incapacitate more assailants than physiological factors, they are also the primary reason for a failure to incapacitate. Their over 800 FPS and some approaching 900 FPS with the hotter +P loads. They argue that the 9mm round has more penetrating power because the round faces less air resistance on its nose as it flies through the air. What kind of insane non-scientific reasoning is this? If a 9mm bullet barely misses the heart or aorta of an adversary, but the heart or aorta of that same person is creased by the slightly larger .40 or .45 caliber round, it can be said with conviction that bullet diameter, expanding or not, really does matter. I have a Ruger American 9 mm full size and its twin in a 45 caliber, I will say yes the 45 caliber is a larger round with more in a way push behind it, but I totally agree with the proper placement of that round when firing is the deciding factor. My department stopped using them in 45 cal because there were enough malfunction to stop. May everyone who reads this have a Blessed Day! Ammunition can really change performance. Also another fact is that my Kimber Colt 45 actually has less recoil than my 9mm with an aluminum frame when my 9mm has a full steel from. Thats why were here right? The quibble is over. SEMPER FI. Temporary cavity is often grossly overrated as a wounding factor, but has historically been one of the primary methods for measuring effectiveness. Even long range shots! Contrary to popular belief, there is no such thing as knock-down power. The only thing that can knock a target down is physiological incapacitation or psychological stress. For a bullet to be effective for law enforcement, it must be able to penetrate the body between 12 and 18 inches to reach large vital organs to cause rapid blood loss. The one he found had the best chance was the .357 magnum. That is closet weights I can readily come up with from factory offerings. There is little or no noticeable difference in wound tracks between 9mm Luger, .40 S&W and .45 Auto premium line rounds. After reading comments from many veterans here, and from what ive seen on the streets, in a true life or death situation give me the largest slug possible. I still prefer the .45. Look at the Walter Scott shooting. The results may surprise many as it did myself. There is a wide range of participants and many of them have never fired a gun of any kind. I settled on a 9-round single-stack .40 S&W that has almost identical dimensions to the same pistol in 9mm. Against bad guys though, gimme a 45 auto. I checked him out, and he's legit as far as that title is concerned and where he works. Im sorry, but the .50 Barrett sucks there is no match grade ammo available for it. I like a simple .45 +P with a lot of lead. However, the .45 would likely be stopped from penetrating but there was a 30% chance, with good shot placement its energy could stop the heart. I see your point. I seem to recall reading in Rangemaster newsletter a month or two ago an FBI paper making the FMJ case. Practice while on the move. I assume that it is cost that is the main concern. Id rather be hit by a small rock than a big one. He was 15.. If Im in my own home in a self-defense scenario, at any distance, Im armed with a 12 gauge, and the whole pistol capacity and power debate is moot. When they strike, the bullets rotate, and more of their surface hits the body. Asking that question around gun owners is like bringing up religion or politics at a party. 9mm Luger offers greater magazine capacity and less recoil/more weapon control at a lower cost. To answer the question which is better 9mm or 45APC. A .45 ACP will encounter greater resistance than a 9mm, but it also carries more weight, albeit at a slower velocity. Great article by the way. I also own both my fathers series 70 .45 (very accurate, low recoil due to mass, gunsmith tuned trigger that feels like butter, and extra fat grips) And a Kahr K40 (small, easy to conceal, but has a HORRENDOUS trigger pull and snappy recoil). 3, both hemolymph ACP and AKP activities of P. clarkii were significantly decreased in the 30 and 50 mg/L groups compared to the control (P < 0.01).Similarly, PO activity also exhibited a significant reduction in the 30 mg/L group (P < 0.05) and the 50 mg/L group (P < 0.01), respectively.However, LZM activity showed a significant increase He also competes in USPSA and 3-gun competitions including numerous top-10 finishes at major matches and championships. I know the argument for +P with lighter bullets, but I settled on these because they meet my two most important criteria for defensive ammo penetration and accuracy. The issue is the 9mm one penetrated which resulted in through and through shots. WebAnswer (1 of 16): It does vary, but most of the time a 5.56mm rifle cartridge will have much more destructive potential than a .45 caliber pistol load does. I also have one that many people will call garbage. So its definitely capable. Theres been many people shot and continue. Thanks. So In a effort to In that encounter, Sgt Gramins shot the suspect 14 times, any one of 6 of those would have almost certainly been fatal wounds. The new .50Ae desert eagle has as much recoil as the 1911/M45 which is unrealistc (the .45 has alot less recoil). Of handgun owners alone, 63 percent owned these for the purpose of protecting themselves against other people, with another 20 percent owning them for protection against animals. Especially when it carries nearly double the mass with the bullet? When the .223 exits the barrel of a gun, it flies at more than 3,200 feet per second, and is still going 1,660 feet per second after traveling 500 yards. Hence poor shot placement, causing a miss or worse the poor animal suffering a slow painful unnecessary death. After the FBI, he served as a Massachusetts Deputy Inspector Generaland is currently a deputy sheriff for Plymouth County, Massachusetts. The only gun I could get to in time was a Glock 17 loaded with 115 grn jhp ammo. After 22 years as a combat soldier, I am kind of partial to the .45 ACP, but I shoot modern, guide rod equipped with aftermarket sights, not rack guns. I totally agree about shot placement. We will stand at 7 to 20 yards (your choice) and shoot each other in the chest. I dont have the time to read it. I have yet to see any really legit fair and unbiased comparison of the 9mm and 45acp calibers. Thank you Rich if you need 15 rounds to put down the assailant youre in trouble already, I have not near the experience of some of the veterans in the service. The best gun is the one that is best in your hands not best someone elses hands. 0.38" Special P, 158 gr non-expanding bullet will, unless it strikes a bone, pass straight through a human body. The question isnt how many people die from being hit with a certain a round, but rather what do they do immediately after being hit?. This is accomplished through simple physics; a larger bullet imparts more force into its target than a smaller one. The projectile is losing velocity and arcing downward. People like the OP of the TIFU have been shot right above their heart and lungs, with .223 and despite a nasty, nasty exit wound and the shot placement, walked it off. 2.1 and 2.5 million defensive gun uses annually, Law Enforcement Assistance Administration, Arming Yourself: A Woman's Guide to Self Defense and Concealed Carry (CCW), Protecting Your Family: A Parent's Guide to Self Defense and Concealed Carry (CCW), Arming the Elderly: A Self-Defense Guide for Senior Citizens, Holsters for Self Defense: A Guide to Carrying Concealed, Arming Toddlers and The "Kinder-Guardians" Program: A Shamefully Bad Idea, Self Defense for LGBT: Self-Protection and Concealed Carry (CCW) for the LGBT Community, Arming the Disabled: A Self-Defense and Concealed Carry Guide for People With Disabilities.
