What movie guns can be fired with no blank adaptor?

Without a projectile you won't get enough pressure in the muzzle to cycle anything no matter how much you adjust.

At least, that's 'common sense' from my end.. Can't say I've ever worked with prop blanks so I can't say for sure.

We have blanked just about every caliber of Desert Eagles. There is a lot more to it than restricting the bore. We have to relocate the gas port and then plug the barrel with a plug of x length. The Desert Eagle to convert is a science and you better know what you are doing as you only have one chance. After that it a new barrel and you start over again.
