YES! On the rare occasion I do use mine, I use the pistol grip. Didn`t even know there was another way of using it. How? Please teach me!![]()
Well, it starts with my spending your money again

Unscrew and discard the pistol grip. Screw a male brass quick-connect in there in its place.
At the end of your hose, put on a full-flow (wide orifice/ball valve) shutoff and screw the female brass quick connect onto that.
Water flow into the foamgun is then controlled with the above-mentioned shutoff via thumb action.
While it might take a little acclimation, and you just never know about those personal preferences, I find that operating the foamgun that way *vastly* eases the whole business of "wash medium in one hand, foamgun spraying at point-of-contact in the other". Just having your hand/wrist somewhat parallel to the foamgun/hose rather than perpendicular to it makes a huge diff for me, but hey...YMMV.
