Frequently Asked Questions

Can a pistol slide break your thumb?

While a pistol slide striking your thumb can be uncomfortable and painful, it is highly unlikely to cause a fracture. The primary issue is that improper thumb placement can interfere with the firearm's cycling mechanism, causing malfunctions.

What is 'slide bite' in firearms?

'Slide bite' refers to the potential injury caused by the reciprocating slide of a semi-automatic handgun striking the shooter's hand, often the web between the thumb and index finger, during recoil. This video tests the severity of such an impact.

What happens if your thumb blocks a pistol slide?

If your thumb obstructs the slide's rearward movement, it will likely prevent the firearm from cycling properly. This means the empty casing won't be ejected, and a new round won't be chambered, leading to a malfunction.

Which pistol was used in the 'Slide Bite' test?

The test was conducted using a Glock 19 pistol chambered in 9mm. The experiment aimed to demonstrate the physical effects of the slide's movement on the shooter's thumb.
