How does this pistol work in the field?
Because this airsoft gun works on gas, it is not working under cold conditions. The main reason for this sidearm is for military simulation and sometimes for CQB (Close Quarter Battle) whereby you yell "Pang" when too close in range (mostly inside 5 meter distance).
