No doubt. I have never fired a fully automatic pistol. I have had the opportunity, thanks to some nice folks at a South Carolina Shooting Club range, but wasn't tempted. The rate of fire is amazingly fast and control seems all but impossible.The caption on the photo notes that it's H.-P. Siggs full auto double glock. Apparently it's a hand crafted abomination, not a factory product.
Yet another example of the just because it's possible, doesn't mean it should be done principle. I can't see a practical application. But, you're right about the mall ninjas.
HOLY COW, that's crazy.I have actually shot several including Mauser, Glock and Beretta and while they are really fun to shoot they elevate "spray and pray" to a whole new level.
The totally coolest of all is the Mexican Trejo which is a .22 very much like the little Llama but full auto. It will dump a 10 round magazine so fast it is virtually impossible to keep from shooting all 10.
Accuracy is probably about minute of phone booth.
