Mac10! Get out of here
I've had Macs (semis), they're like, made in your neighbor's garage.
Now, the Beretta 93R is a MACHINE! A piece of Art.
I was fortunate enough to coonfinger one that a friend of mine owns in a distant land far away. It was late at night in the city, so I did not get to shoot it. I was going absolutely nuts.
They are select fire for single or 3 round bursts. A shoulder stock can be added, though I have never seen one.
Most people think you just wrap your weak hand around the fold down grip and go to town. But that is not entirely true. It you notice, the trigger gaurd is almost double in size. That is so you can wrap your weak Thumb through the trigger gaurd as you grip the fold down grip. This enhances the guns stability greatly.
I've been lusting for this gun since I first held it 20 years ago.
Truly Awesome. Even if you DON'T like the 92.
