Comparing the flash hiders, I think the simple cone works better; to my eye, the more cylindrical style on the second post looks like a modern suppressor and pulls the weapon away from the 1920s design cues that most blasters have.
On the other hand, the second scope feels more Star-Warsy to me. Although I'm a firm believer that any Star Wars weapon should be able to mount any of the scopes - that is, in my opinion a sighting device in Star Wars is not normally an integral part of the weapon, just as it isn't in the real world.
On both, the not-actually-a-hammer really jumps out to me, because it's clearly based on a C96 hammer - and it's just as clearly not actually doing anything useful. Were it me, I think I'd either just delete that part entirely or extend it underneath, with a circular profile, so that it looked like it could cock back.
Overall, though, this is very impressive! The general feel works with other Star Wars weapons, and this comes across as a sidearm someone might actually carry. My comments are meant to help inspire you, not drag you down - at the end of the day, make it work for you!
