Hot brass is a pet peeve. It always seems to get stuck somewhere in my shirt rather than just falling out. also, as a lefty, I have a problem with it sometimes hitting me in the face. Last time I fired a bullpup-style weapon the brass nailed me in the face, splitting my lip!
Yikes!
I shoot southpaw too. Never shot a left handed gun. Hot powder in the eyes can be a bitch!
