Modifications to a pistol to allow blank firing?
What modifications are needed to allow a semi-automatic pistol to fire blank ammo?
The reason I ask is that on various film prop sites I have come across a photo of a gun, ( for an example see accompanying image), and the phrase,
"Note how the gun has clearly been blank converted."
I can guess at the reasons but does anyone know?
(Don't even bother trying to google this.. .you will get thousands of pages on how to convert a blank gun to fire real ammo.)
This is from the film, Heat.
