I am not interested in such a gun. I own a Winchester 1300 stocked gun and took classes with it from Tom Givens and Steve Moses. I ran it in our local TX club match shotgun stages.
I still read posts about Shockwaves and the LGS was selling a bunch. I previously asked about agencies using them.
So my question is whether anybody has done an empirical test of running one of them through a realistic training or match setup as compared to a standard gun?
