The traditional arguments still prevail in some ways. In the case of the .45 ACP, the new standard cartridge pressure is 21,000 psi (140 MPa) and the SAAMI .45 ACP +P standard is 23,000 psi (160 MPa). Some 45 ACP loads show all the velocity we could ask for. Now retired, I upgraded to a FNHUSA FNX-45 Tactical with a LWI muzzle brake. Or does that add too many variables? I really don’t care if is heavy. And if my life and the life of those I love is in the gun I carry Round Nose Full Metal Jacket: Case.  While high capacity firearms are available in .45 ACP, the greater length and diameter of the .45 ACP means that the grip of the pistol must be longer and wider than the grip of a comparable pistol of a smaller caliber; this increase in grip size can make the pistol difficult to use for shooters with smaller hands. I would go so far as to say that in terms of functional lethality, the short 3.3” barrel loses nothing to the longer barrels. Excess velocity just creates recoil and muzzle blast. This is a common practice for updating older cartridges to match the better quality of materials and workmanship in modern firearms.. Range / Target: Muzzle Velocity. I agree with Ya Mamma. SAAMI specifications for 45 acp. Going to sell my full size 45’s. A longer barrel will ALWAYS produce higher muzzle velocity regardless of which s&w m&p is ur bff. “Accuracy” and follow up shots in a gunfight is really up to the shooter’s abilities. , Most ammunition manufacturers also market what are termed "+P" (pronounced "plus P", designating overpressure ammunition) loadings in pistol ammunition, including the .45 ACP.

The .45 ACP is regarded as a top self-defense round in terms of stopping power and recoil. ARCHIVED; Armory » Reloading. The .45 is a fine caliber for a variety of tasks today. The ammunition I received ranged from simple ball loads to exotic self-defense rounds that could easily be called art due to the quality of their machining. doubled in size…and since .45 ACP is bigger to start with, it became massive in the end. 45 ACP velocity testing considering that it is shorter than most people think a .45 ACP handgun should be. To equal the impact of a .45 ACP bullet, the 1-pound weight needs a velocity of 27.1 fps and must be dropped from a height of 11.4 feet. I taught quite a few classes in the Hudson Valley NY area, generally Federal, State and/or Municipal LE Agencies. BE. Call us at (540) 898-9256, If you have questions. There is also a reduced likelihood of overpenetration, meaning that it is more likely that the projectile will transfer all of its kinetic energy to the intended target, thus more reliably incapacitating them. The Rowland operates at a developer established 40,000 psi (280 MPa) SAAMI and may only be used within a select group of firearms significantly modified for this purpose; the Rowland case is 0.057 inches (1.4 mm) longer specifically to prevent it from being chambered in standard .45 ACP firearms. 45 ACP velocity adventure, I was imagining that there would be a large difference between the standard 5” barrel and the short 3.3” on the S&W Shield. I am currently using an H&G 68 clone and it seems to work fine. The larger guns are easier to aim due to a longer sight radius, but they suffer from a weight penalty and low capacity for their size. Compare all 45 ACP ammunition … The cartridge also comes in various specialty rounds of varying weights and performance levels.. In its non-expanding full metal jacket (FMJ) version, the .45 ACP cartridge has a reputation for effectiveness against human targets because its heavy mass has the capacity to penetrate tissue deeply and damage the central nervous system, and its large 11.5mm diameter creates a more substantial permanent wound channel than other calibers, which can lower blood pressure rapidly if critical organs of the circulatory system are hit. When I began this . But I carry a 9MM Shield because of the load out, and the size and weight. The standard issue military .45 ACP round has a 230-grain bullet that travels at approximately 830 feet per second when fired from the government issue M1911A1 pistol. Therefore it makes logistical sense that velocity lost it shorter barrels is quite small compared to other calibers. .45 ACP maximum C.I.P. The cartridge expands to an average of 0.75” inches, but the Remington FMJ expands to 0.45”. The cartridge/pistol combination was quite successful but not satisfactory for U.S. military purposes.

Today, AR-style weapons are available in 9-millimeter, 10-millimeter, .45 ACP, .40. I found that the truth lies somewhere in the middle of these points of view based on my results. Bottom line, the .45 ACP is the better self-defense cartridge, and does its best work at standard velocity. Today, most NATO militaries use sidearms chambered for the 9×19mm Parabellum cartridge, but the effectiveness of the .45 ACP cartridge has ensured its continued popularity with large caliber sport shooters, especially in the United States. Most .45 suppressors must be fired "wet" (with an ablative medium, usually oil or water) to bring sound levels down to "hearing-safe" (under 140 dB, generally).. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power for use against human targets. They noted, however, training was critical to make sure a soldier could score a hit in a vulnerable part of the body. Slow fire is at reduces 50 yard targets at 25 yards.

The first production, at Frankford Arsenal, was marked "F A 8 11", for the August 1911 date. The downside to the use of .45 ACP in suppressed weapons is that increasing the diameter of the passage through a suppressor decreases the suppressor's efficiency; thus, while .45 ACP is among the most powerful suppressed pistol rounds, it is also one of the loudest. Every load and weapon tested are currently commercially available and unaltered from their factory form. This means that .45 ACP chambered arms in C.I.P. Most quality bullets, in all the defensive handgun calibers are designed to work(expand) at a fairly wide… Read more ». You are wrong however about the 9mm. But many modern pistols have adopted the cartridge into double-stacked magazine designs, though this increases the pistol's width. Overall, it appears the .45 Auto is slightly faster in comparable products, but shooters will not see a significant difference between the two. Another area to address is velocity. Probably not. This means the cartridge is loaded to a higher maximum pressure level than the original SAAMI cartridge standard, generating higher velocity and more muzzle energy. .45 Automatic Pistol Ball Cartridge, Model of 1911", a 1.273 in (32.3 mm) long round with a bullet weight of 230 grains (15 g). 543 ft. lbs.

Many often wonder about the difference between 45 Colt vs. 45 ACP ammo – the former was a heavy, fast-moving bullet at 255 gr and 900+ fps, and was vital in settling and civilizing the American West. Yes sir, AZDPS. The colder temperature allows the guns to remain cool between strings and remove error due to the weapon heating up. These cartridges have the same external dimensions as the standard-pressure cartridges and will chamber and fire in all firearms designed for the standard-pressure loadings. After the poor performance of the Army's .38 Long Colt pistols evidenced during the Philippine–American War (1899–1902), Thompson insisted on a more capable pistol cartridge.. The results proved interesting to say the least. 50 Round Box. It has relatively low muzzle blast and flash, and it produces a stout, but manageable recoil in handguns, made worse in compact models. In fact, standard pressure 230 grain FMJ loads are, perhaps, the .45 owner’s best choice for bears since they penetrate deep and make wider wounds than non-expanding 10mm’s. To get a picture of the modern .45 ACP's velocity, I contacted several manufacturers and received 33 ammunition offerings to test. In the second round of evaluations in 1910, the Colt design passed the extensive testing with no failures, while the Savage design suffered 37 stoppages or parts failures. Ron, where were you a LEO carrying a P220? This is a video of … During the late 19th century and early 20th century, the U.S. Cavalry began trials to replace their sidearm arsenal of issued .45 Colt Single Action Army (SAA) in favor of the more modern and versatile double-action revolver in .45 Colt.

Colt had been working with Browning on a .41 caliber cartridge in 1904, and in 1905, when the Cavalry asked for a .45 caliber equivalent, Colt modified the pistol design to fire an enlarged version of the prototype .41 round. Does it matter in terms of terminal performance within reasonably defensible distances? A .45 averages about 11.3”-14.3” penetration. NO WAY. The latter inevitably produce a highly compressed shock wave, audible as a loud "crack", a small sonic boom, while they travel through the air. The Super provides approximately 20% greater velocity than the .45 ACP +P; the Rowland approximately 40% greater velocity than the .45 ACP +P. Out of the box I considered it to be the finest DA/SA pistol I’d fired in the caliber.

AZ perhaps. The .45 ACP is an inherently subsonic cartridge that’s designed for optimum performance at those lower speeds. The small size (comparable to a Glock 43 Handgun) combined with no loss of ballistic efficiency make it a potent choice for fans of the .45 ACP. Tracer ammunition for the .45 ACP was manufactured by Frankford Arsenal and by Remington Arms. WHAT? My CCW is a Colt Commander, 10 rnd mag, I have put over 3500 rnds through it and it has not failed to function properly yet. Standard 9mm NATO ammunition has limited armor penetration capability − a deficiency with .45 ACP whose large, slow bullet does not penetrate armor to any great extent. The most unexpected thing aside from the general similarity of all loads across all barrel lengths was that the longest barrel wasn’t the fastest. It is my opinion that this caliber isn’t going anywhere anytime fast. This is a significantly large permanent wound cavity for a handgun projectile. The cartridge also has relatively low muzzle blast and flash, as well as moderate recoil. We offer choices of excellent quality range ammo, the most proven hollow points and specialty rounds in all of the most popular calibers. The .45 ACP handguns ranked last, largely due to increased recoil. The light self-defense loads are essentially comparable to 9mm of similar bullet weight while most heavier loads generate a much heavier amount of recoil than many shooters would find comfortable. I have five 1911s in barrel lengths from the 3″ to 5″ and the S&W is to me the most accurate. The weapon has the same capacity as the 1911 with seven or eight rounds onboard, but is less than half the weight. Sorry buddy but your statistics are flawed and biased.

With standard (not extended) single-stack magazines, pistols based on the 1911 design commonly hold 8 rounds or less. The low velocity and heavy weight of the .45 is great for striking large areas and creating large wounds. , Because of its large diameter and straight-walled design, the .45 ACP geometry is the highest power-per-pressure production, repeating round in existence. I have personally loaded for and tried various loads on a 45 ACP from barrels as short as 3 inches to as long as 18 inches and find velocity differences Quite minor. Popular derivative versions of the .45 ACP are .45 Super and .460 Rowland. [ARCHIVED THREAD] - .45 ACP Loads - Velocity and Bullet Types.

The cartridge was designed by John Browning for Colt, but the most influential person in selecting the cartridge was Army Ordnance member Gen. John T. Thompson. The .45 has benefited from modern manufacturing processes and improved bullet technology. I recently bought a Ruger SR1911, VERY well made and VERY accurate. The other camp I often encounter and debate argues that the .45 ACP offers a profound advantage due to the bullet mass and ‘stopping power’ available, the adage being that one .45 is worth two or three ‘little nines’ in a fight. The cartridge expands to approximately 0.35 to 0.72”. USA – -(Ammoland.com)- I got into a discussion with several local gentlemen over last Christmas about things typical to those who frequent gun stores. It was eventually evaluated that the .38-caliber round was significantly less effective in overall stopping-power than the .45 Colt against determined opponents in cases such as the Moro juramentado warriors, who were encountered in the Moro Rebellion. Overview. After two years of testing, one of the final FBI comments was that services that adopt (or stay with) .40 S&W or .45 ACP did so at the risk of increased recoil and a possible reduction in accuracy as 9 x 19mm with premium quality ammunition had nearly exactly the same performance. The low muzzle velocity also makes the bullet drop over long ranges, making hits more difficult; however, it is important to note that the vast majority of self-defense situations involving handguns typically occur at close ranges. 45 acp 230 gr initial velocity is 830 (slightly slower than average 45 velocity), and the 9mm 124 gr initial velocity is 1110 (slightly slower than average 9mm velocity). It is, in my mind, best suited to single-stack carry pistols given the modern pistols like the Shield 45 that can tame it and lose nothing in the process. 45 ACP Muzzle Velocity. @ 1,150 fps/M.E. What ballistics aficionados tend to argue is “Stoppng Power” which is the ability of a round to stop your attacker. I was fortunate to have a small pile of different .45 pistols passing through at the time, so I tested actual velocity from a range of pistols from compact to full-size. I’m a fan of the .45. I wonder why the Blazer 230 grain aluminum and brass cased ammo is so slow? I have put hundreds of rounds of multiple weights and shapes through it, without a malfunction. It is a great cartridge. Doesn’t match what I have seen, but I have shot “identical” guns with “identical” rounds and seen a 75 fps difference between the two…. OldCowboy, the anti-gun former Constitution State aka Connecticut, the DES&PP aka CSP now carry the SIG P220 in .45ACP….. Glock was interested in the deal but CT does not allow their formerly owned(trade-in-guns) to be sold to the public…Glock refused to be told how to run their business…wonder what SIG did with the P229 .40SW that CSP traded in?
