Doesn't the Prop Store bug you?

[MT2008]

But doesn't converting a gun to blank fire also pretty much destroy it? Sometimes Prop Store sells the ones that were converted to blank fire for American customers, still in firing state (like Denzel's Browning HP from "American Gangster"), and they always mention that the weapon is incapable of functioning with live ammo due to the conversion - although it still has to go through an FFL.

Don't you cringe whenever you see rare firearms get converted to blank fire?
