In any case, gelatin isn’t a human being, and water is simply a means of comparison. Water jugs are six-inches wide and results are usually within 10 percent of gelatin results in penetration and expansion.Īlthough not as precise as gelatin, you may wish to check if the duty load also performs well in a subcompact and water is a good cheap basis of comparing loads. I have tested quite a few handguns cartridges using water jugs as the media for penetration and expansion. 40 is the ideal cartridge and the larger calibers may represent a point of diminishing return.Ĭertainly control, magazine capacity and compactness favor the. 45 ACP cartridge, there is a consensus that perhaps the. 40 S&W cartridge and the frame size needed to contain the 10mm or. When you consider the balance of expansion and penetration in the. It must be controlled with proper technique. Recoil and report mean you are firing a powerful cartridge. 40 does not reflect a considerable difference in control with a trained shooter. The difference in recoil between the 9mm and. Many shooters feel that a PF of 200 is the upper level at which a shooter can control a handgun well.Ī PF of 150 to 170 is better for accomplished shooters. While the PF doesn’t consider weapon weight, it is useful to compare the recoil of various cartridges. For example, a 200-grain bullet at 1,000 fps would have a PF of 200. The weight of the bullet is multiplied by the velocity and then divided by 1,000 to come up with the PF. It has been used as a rating for Major and Minor rules in competition and also to gauge the suitability of a handgun for personal defense. Power and ControlĪ power-factor rating was developed to compare handgun calibers. Most of us can handle the GLOCK 17/22 frame well. 45 ACP cartridge, but my hand size does not allow me to handle the big frame GLOCK pistols well. 45 ACP is always an answer, but the size, weight and perhaps more importantly grip width of full-size, service-grade. The goal was to offer superior wound ballistics. 40 wasn’t to produce a weapon that is as controllable as the 9mm, because we had the 9mm. The same might be said of the SIG Sauer P229 in. 40 Smith & Wesson offers a manageable system. We know the subcompacts are difficult to manage with this high-intensity, big-bore cartridge, but what about service-size pistols? Beginning with GLOCK 23-size pistols, the. For female shooters, recoil can be startling. 40 caliber are often too much pistol for most shooters to handle the recoil in rapid-fire. 40 have done well, while those using subcompact pistols have not. 40 S&W handguns come through my concealed carry classes. 40 simply did not catch on as it did with those in uniform. 40 S&W is already much less popular than the 9mm Luger or. The question of control has come up from time to time, but in my experience it relates primarily to subcompact pistols. 40-caliber handguns have demonstrated good to excellent all-around results. 45” more alike than different when compared to a rifle. Handguns are not very powerful compared to a rifle cartridge, with the “weak. This caliber has proven as effective as a handgun cartridge is likely to be. The SIG P229, GLOCK Model 22 and the Beretta PX4 Storm are among them. 40 Smith & Wesson cartridge and service-size handguns. 40?Īmong the most successful handgun and cartridge combinations of the past 30 years has been the. 40 for defense, standard-pressure loads should be used in compact handguns. As for the actual expansion of hollow-point bullets in bodies, they cannot be counted on 100 percent. The standard of evidence required in traffic court would not allow their admission. So-called stopping power studies involving secret sources and anonymous reports have a validity of zero. The only repeatable and verifiable means we have of gauging wound potential is by studying the effects of a bullet in artificial media. Coupled with the constant of adequate penetration, a larger caliber always has more potential to do damage, cause blood loss, and shut down the adversary’s body. The wound potential of a cartridge depends upon the level of penetration, the diameter of the bullet and bullet expansion. Among the things I have learned in researching wound potential, is that only actual damage counts for anything.
