![]() What Is More Power Really Good for in a Pistol? You're in a colder climate, look for 14" or more to offset heavy clothing. 380Īmmo gets at least 12" of penetration in ballistic gel tests, and if Shot placement: Where you place those holes in the threat.įor.Permanent wound cavity: The size of the holes you punch in the threat.Only two things matter when you're shooting 9mm or stronger ammo: With a pistol, more power won't stop the threat faster. There's a saying: "A pistol's a pistol, and a rifle's a rifle". Here's Johann Boden with Federal Ammunition explaining more:īut with a rifle, you can effectively "hit" those spots even if you missed them by a few inches.Ī rifle bullet hits so hard that the temporary cavity becomes a permanent cavity. Only rifle rounds and a new type of pistol ammoĬan exceed the elasticity of human tissue, and cause the temporary cavity to become permanent. It may feel unpleasant for a split second, but it's not what stops a threat. Human tissue is elastic, so much that the temporary cavity is just that: temporary. More powerful pistol rounds make bigger temporary cavitites in gel. If you've looked at ballistic gel tests, you can see the temporary cavity is much larger than the permanent one. When a bullet enters the human body, it creates a temporary wound cavity and a permanent wound cavity. Why? This will sound a bit icky, but we have to talk about terminal ballistics: what bullets do when they hit a live target. Going for more power in a pistol usually has no practical effect. Longer barrels concentrate more power behind the bullet, but don't add any blast. Part of the blast erupts outside the barrel, making brighter, louder flashes. If a barrel is too short, it's like removing some of the blast behind the bullet. ![]() Pistol rounds are designed to burn all that gunpowder in the first 3-4 inches of barrel. Why do the gains drop off? When you fire a pistol, gunpowder in the ammunition ignites, creating a small blast. When you fire a loaded pistol, the bullet travels out the barrel, exiting the muzzle, or forward end of the barrel. On a Beretta 92, the slide is mostly cut out, with the barrel showing: Bull Barrels for Accuracy and Faster Fire.What Can I Get Instead of a Longer Barrel?.What Is More Power Really Good for in a Pistol?.We'll cover what a pistol barrel is, how you can upgrade it to help you defend yourself,Īnd address common questions and myths using expert testimony, physics, and case studies from real-world shootings. A pistol's barrel imparts power to your shots, and affects accuracy, but not the way you think. ![]()
