Mossberg Shockwave ?

Today I stopped by a gun show which had both the 12 gauge and 20 gauge models on display. For some reason I wanted to check it out.

I handled the 12 gauge Mossberg Shockwave and actuated the action a couple of times.

I am not sure how practical it is but for some strange reason it felt good in the hand. I can't describe it. But I am wondering how good they really are?

Any experiences?
