I think I have to agree with Lloyd. I really like a straight grip for grouse,.just feels faster all my waterfowl shotguns have pistol.grips.
I'm sitting looking at my wall with eight hammer sxs from from 1850s to 1960s all double triggers. The three earliest ones have straight grips and the other five pistol grips.
In the safe my hunting shotguns are all two trigger pistol grip except for two with straight grips and they are the lightest short barrel fast handling of the bunch. I only have one single trigger left and that is my old Win 101trap gun and a still have it because it is an old friend and I would have a hard time letting it go,.haven't.shot.it.in ten years but.it.feals.good.to.have.it.
