When it came to the Shockwave, I decided that discretion was the better part of valor.
I handed it back to Dad after standing there for about two minutes trying to figure out how the hell I was going to shoot it without loosing it.
So it's now the second gun I can't/won't shoot, the other being the Cruiser, because it's just an accident waiting to happen. I'm game for recoil, I'm cool with a little pain and I'll work through those things, but I'm not messing with something I literally cannot keep a grip on and is going to go flying through the air.
That said, Dad also has trouble with it and he's great with the Cruiser. He's been able to work at it and improve, but there was a learning curve on it.
