Sounds like some tactical-ninja-black-op-wannabe piece of bogus-ness. 
Is it real? I'd never heard of a press check until I started swimming around on the internet. If this is a way to check if a gun is loaded then it's different that what I have been taught. I either pull back the slide on a semi-auto, pop open the cylinder on a revolver, or open the action via bolt or op-rod on a rifle to see if my gun is loaded. What's the deal with a press check?
Thanks.:
