Snap cap
A snap cap is a
The term "snap cap" is a generic trademark of the fake cartridge originally introduced by American firearm accessory brand "A-Zoom", and is a word play on percussion cap. It is now used to refer to any accessory product made to perform similar function.[1]
Description
A snap cap is used to ensure that
Some snap caps are made of a soft aluminum coated with paint. Other snap caps are manufactured using traditional brass shell casings and injecting a polymer material,[2] while others are made from a solid piece of plastic, including via 3D printing.[citation needed]
Uses
Function check
Snap caps are used to confirm a firearm is functioning properly without using live ammunition. In the case of some repeating firearms, it can be used to ensure the magazine is feeding ammunition properly up the feed ramp and into the chamber.[citation needed]
Dry-fire practice
Snap caps are used for general dry-firing practice. There is some debate as to if dry firing a handgun may cause damage to the firing pin in a modern firearm. Using a snap cap or dummy round eliminates any potential risk of doing so if the snap cap has a solid primer cup. Some snap caps are made without a primer cup, and thus do not address this potential concern.[citation needed]
Malfunction training
Snap caps and action-proving dummy cartridges also work as a training tool to simulate firearm malfunctions, the same as a dud would. The shooter loads one or more snap caps into the firearm or magazine along with live rounds; when the trigger is pulled with a snap cap in the chamber, a failure to fire occurs. The shooter can then practice clearing the bad round, which generally requires manually cycling the slide of a semi-automatic pistol.[citation needed]
Trigger control training
As with malfunction training, snap caps are loaded along with live rounds, so that when the trigger is pulled with a snap cap in the chamber, the firearm does not fire. Here, the intent is to observe whether the shooter maintained proper trigger control (that is, did not flinch). This is often referred to as a ball and dummy drill.[3][4]
