No.
You gain a small amount of grit, and the ability to perform a single 1st-level deed from the gunslinger class feature of the same name. At the start of the day, you gain 1 grit point, though throughout the day you can gain grit points up to a maximum of your Wisdom modifier (minimum 1). You can regain grit using the rules for the grit gunslinger class feature. You can spend this grit to perform the 1st-level deed you chose and any other deed you gain through feats or magic items.Since the Archtype's deeds replace the Gunslinger's class feature, you can't take a deed from an archtype(at that point, it's not longer the Gunslinger's class feature, it's the Mysterious Stranger/Musket Master/Gun Tank's class feature instead).Each alternate class feature [from an archtype] replaces a specific class feature from its parent class. For example, the elemental fist class feature of the monk of the four winds replaces the stunning fist class feature of the monk.
