How does a pistol know the magazine is empty?

When you’ve fired the last round in your pistol’s magazine, the magazine’s follower pushes up against the slide stop and causes it to catch in a recess in the pistol’s slide. This, in turn, causes the slide to be locked back. When you see and/or feel this, it’s a good indication your pistol is out of ammo.

How long does a gun magazine last?

Some ammunition manufacturers recommend rotating service-related ammunition as little as every six months. By following that guide line, magazines would remain fully loaded a maximum of six months before being unloaded and reloaded.

Are ballistics accurate?

The test-firing results only scratch the surface of ballistic fingerprinting’s problems. The experts concluded it’s unknown whether cartridges fired after typical firearm break-in and wear can at all be matched to the cartridge fired when the gun was new. “They are not permanently defined like fingerprints or DNA.”

What happens if your fingerprints are on a gun?

If the legal owners prints are on it in addition to yours and he had reported it stolen – you might be charged. If your prints are on a weapon found at a crime scene and everyone else has an alibi – you might be charged.

Why does a gun recoil when a bullet is fired from it?

When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.

Why do Bullets kick when they hit the barrel?

Instead, they are supposed to start burning relatively slowly, through a process called deflagration, so the cartridge moves off smoothly down the gun. They burn faster as the bullet accelerates down the barrel, giving it a maximum “kicking” force just as it comes out of the end.

Why do guns wobble when fired from long distances?

Over longer distances, they follow a slight downward curve because gravity tugs them toward the ground as they go along. Air resistance and the spinning, gyroscopic motion of a bullet complicate things too. Usually, because of recoil, the person firing wobbles the gun slightly when the bullet emerges.

Why does my pistol slide lock back when I shoot?

It’s there for a reason. When you’ve fired the last round in your pistol’s magazine, the magazine’s follower pushes up against the slide stop and causes it to catch in a recess in the pistol’s slide. This, in turn, causes the slide to be locked back.
