It does look like crap but there is absolutely no reason they couldn't make safe prop guns. I cannot overstate how little this would matter for the average film budget and it's an investment in your employees not dying and the costs involved in all that cause you can KEEP THOSE PROP GUNS and use them in subsequent movies. Just make it something that can be installed in a real gun easily. As I posted above, I made something pretty suitable in like a day making it up as I went.
