I bought a Charger when they first came out. The guns are as cool as a pistol can be but it sold and went away a few months ago.
I tried a long relief scope then a red dot on it but absolutely could not figure out a way to shoot it well, while wearing trifocal glasses. Friends loved that Charger but it didn't work for me.
I have a First Gen and I love the hell out of it, But not really sure why...... It's ugly, it's heavy (using one hand to fire), but I had to have one............
