Pros - Love the different properties of the various firearms including the variety of "called shots" (Trick Shots) combined with the Grit system as well as the misfire mechanic. I appreciate that the subclass is written suscinctly and as clear as possible (but I did have to reread some mechanics two or three times before they became clear and now I can't figure out how I didn't understand it the first time).
Cons - I appreciate that Matt sees how futuristic guns and gunpowder based weapons are in the typical 5e settings so some firearms need to be crafted and not simply bought (regardless of the rarity of the weapon). However to require a mechanic like crafting and then not actually have a system built with it painfully reminds me how poisons have been handled in 5e. Wish there was more to the crafting aspects! Conceptually great but implementation feels like it is only done half way.
