The pk3 also contains the list of sounds I used (for crediting their authors) and improved weapon.cfg (better flash dynamic light color and added impactSound).
The shot sound is a bit short/abrupt (continuous fire doesn't create "overlay" effects, which usually make the weapon sound more interesting) but apart from that this sounds good to me. Impact sound could be a bit louder.
