Gunslinger's Grit and Deeds

[Lui]

May I use two or more different deeds on a single action, if I expend enough grit points?

[Volos]

No, unless you get a feat or ability that states otherwise. You can't do two of anything, much less Gunslinger Deeds, on the same action... unless you have a feat or ability that states otherwise. For Gunslinger Deeds I do not believe there are any feats or abilities that will do this for you, but I may be mistaken.
