I had a couple of small ideas for additions that could be made to the _clientdeal file to make gunshot wounds in PvP more dynamic/realistic, feel free to ignore this at your own discretion

Fracture chance
Being shot has a chance of causing a fracture in that body location. It would just be a setFractureTime(21) and the chance probability could probably be pretty easily configurable in sandbox options

Straight through chance
A chance that being shot does not cause a lodged bullet. Again, probability could be set fairly easily in sandbox options

I could write up the code for these later tonight when I get the chance
