That flame out the end of the gun would be the muzzle flash.

The blob is already gone. I will say one thing though, I'm not entirely pleased with the smoke effect I had to use. I tried using particles coming out the end of the gun, and then curving upward (like you would see in an old western from a six-shooter), but the damned wind modifier REFUSED to work! Didn't matter what kind or particle source I had! I spent all day yesterday trying to get it to work, and eventually just gave up. What you see there is a simple basic spray with lens effect glow applied.
