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.
Moving on to the accuracy portion this indoor Sea Can Field Test I setup a clean paper target 30 feet down range and placed 10 shots into it using a rested and seated shooting position. The grouping was a bit all over the place but the bulk of the roods did hit pretty close to the center of the target in about a 3-4 inch grouping. 2 of the shots did go a bit high on me. I feel that perhaps because of the higher velocity that heavier Airsoft BB's may perform better in the KWC M40 Extended Barrel CO2 Blowback Airsoft Pistol.
All in all the KWC M40 Extended Barrel CO2 Blowback Airsoft Pistol is a nice shooter with heavy blowback and a light Single Action Only Trigger. The high velocity woful make it a great out doors Airsoft Sidearm.
