Just found out about this incredible piece of weaponry. Based on the CZ75, it can fire most pistol calibers using hot-swappable parts. This is accomplished by doing a quick unlock of the "top end" of this gun and putting in a top end that fires your desired caliber while of course changing the magazines. Not only that, it's reliable as hell, and on the cheap end. You can pick one up for around a modest $500 these days. Holy hell. How come I've never heard of this pistol?
