Who in their right mind would trust their life to one?
That said, my Jimenez JA-22 (the current new and improved model) works fine and it is fun to shoot. That said, it is more of a gimmick gun.
I shot it as my BUG in a steel match special stage this fall. Of course, the safety is the big problem. You just barely bump it and it engages causing you to lock up. I still finished mid-pack with it.
But it was the hit of the match. Who in their right mind brings a JA-22 as their BUG...?
