In this Field Test Shooting Review I put the KWC M40 Extended Barrel CO2 Blowback Airsoft Pistol through my typical Sea Can shooting tests to see what the real world velocity and accuracy are. I made sure i had a brand new 12 gram CO2 in the gun and I used .20 gram plastic Airsoft BB's for the entire test. The temperature was around 17 degrees Celsius which is not too hot or too cold.
Starting with my Chronograph Feet Per Second testing I placed 5 shots with my KWC M40 Extended Barrel CO2 Blowback Airsoft Pistol through my Chrony Chronograph and averaged a nice 397 fps, the fastest shot was 408 fps and the slowest was 387 fps...
