I was reluctant to pick up the Gunslinger, but I'm really glad that I did. I think that the Grit points give players a solid resource to track use to pull off soe interesting things as they level up. Trick shots are great because I have so many players who say they want to aim for a particular part of a target, so that gives it a mechanical benefit rather than having to improv something each time.

I also really like how fast the Gunlsinger becomes over time, Quickdraw and Lightning Reload make them downright deadly.

While looking through the reviews I noticed some folks pointing out that this doesn't offer anything outside of combat, which is true to a point. Personally I think Gunsmith is loaded with potential uses for story hooks, so I don't know that I totally agree with that criticism.

Part of me wants to sue how a Fighter with this archetype multiclassing with an Artificer from Unerarthed Arcana would get on. I just picture some crazy scenarios with the thunder cannon and the Gunslinger's other firearms.
