I sure hope the 'toolbag' you are referring to wasn't me....
I shoot my HD gun there all the time, just to put some rds thru it. Blackhawk pistol grip, 20in barrel and mag extension. I hit 95% of the clays and I am VERY safe with all my firearms.
So what is wrong with shooting with a pistol grip?
Nothing wrong with it I suppose if that's your gig. I guess I'm used to proper sport shotgunning, ..... you know, with a stock and all.
I call BS on the percentage. You are welcome to come with me to Hopkins or Shraders next time we go, you hit 95 out of 100 birds with your gun and I'll GIVE you mine.
