For most of my service career, I was interested in a handgun load with a good balance of penetration and expansion. Penetration is the single most important factor in wound potential. Without adequate penetration, we have nothing. During the majority of this time, I also worked in rural areas.
The sidearm was usually a .45 automatic although the .357 Magnum handguns online at CheaperThanDirt.com” href=”http://www.cheaperthandirt.com/Search.aspx?q=.357+magnum&site=All+Products&num=15&s=eyJPTERDQVRFR09SWVFVRVJZUEFSQU0iOltdLCJPTERCUkFORFFVRVJZUEFSQU0iOltdLCJPTERXQVJFSE9VU0VRVUVSWVBBUkFNIjpbXSwiT0xERklMVEVSQllRVUVSWVBBUkFNIjpbIkluIFN0b2NrIE9ubHkiXX0=&sb=priceHigh&pn=25&utm_source=blog&utm_medium=social&utm_content=bcampbell&utm_campaign=20131210-social-blog-.357-magnum-handgun-category” target=”_blank”>.357 Magnum and .44 Special were also carried at times. When it comes to home defense and urban environments, the demands may change quickly. A bullet that does not, and must not, ricochet isn’t easily designed and built. A handgun bullet with sufficient velocity to ensure rapid expansion isn’t common. Even when the design criteria is good, convincing a lightweight bullet to cycle properly at normal handgun velocity is not easy.
I studied an unfortunate incident in which a peace officer was putting down a horse that had been hit by a truck. To stop needless suffering, the officer fired into the body with his .357 Magnum handgun. The bullet fully penetrated, bounced off the road and struck another officer—against all odds.
On another occasion, I observed a .41 Magnum bullet that passed through a car door, struck a heavy seat bracing and deflected out the roof of the vehicle. On another case, a bullet fired into a vehicle door hit the heavy metal window regulator and bounced directly back toward the officer that fired the round—fortunately missing him. Similarly, a .45 caliber 230-grain bullet struck a vehicle side window at sufficient angle to bounce away and careen down the road. As you can see bullets can do incredible things. There are times where maximum penetration is highly desirable, and occasions where increased penetration presents a great hazard.
The PowerStrike is Reliable
The bullet, at 90 grains, reaches nearly 1300 fps from the Glock 19 and well over 1250 fps from the shorter barrel of the SAR B6 pistol used for most of the testing. The PowerStrike proved completely reliable. By carefully developing a proper powder charge, good bullet pull and excellent quality control, Allegiance Ammunition has given us a cartridge that is reliable in the self-loading action. Just the same, no matter what loading you choose in your personal defense handgun, be certain to proof the handgun with at least a box of ammunition. There is no standard other than complete reliability that is acceptable for personal defense.
The 9mm PowerStrike rounds were tested in a Glock 19, a SIG P 250 and the EAA SAR B6 9mm pistol. Function was good with no failures to feed, chamber fire or eject.
The PowerStrike Design
The PowerStrike achieves its frangible and safe design by a composite of materials. The bullet nose is pressed into the jacket on meeting resistance and the projectile fragments. That seems simple enough.
The bullet design results in little chance of ricochet or over penetration or perforation of the adversary. The primary responsibility of the homeowner is to strike his or her target. In the event of a miss, the PowerStrike offers a degree of frangibility, but the best outcome is to hit the threat and that the bullet fragments and does not penetrate the target. The testing performed included using gallon water jugs. The PowerStrike is not only frangible but impressively so, scattering the water jugs and doubtlessly giving up all of its energy quickly.
In firing at concrete blocks and other likely home material, the PowerStrike proved to be as frangible as any loading. The PowerStrike is affordable compared to some loads, and this allows the user to test the firearm sufficiently with a good amount of ammunition. For many users, the PowerStrike loading is an ideal choice for home or urban defense. I have adopted the loading as an option in the SIG handgun that is kept at home ready. I cannot give a higher recommendation.
