Buy the magazine: KWCKW148

Accuracy: I placed 5 shots through my chronograph and averaged a nice 397 FPS. THe fastest shot was 408 FPS with the slowest being 387 FPS. Moving onto the accuracy portion, the grouping was a bit all over the place but the bulk of the rounds did hit pretty close to the center of the target in a 3-4 inch grouping. 2 of the shots did go a little high on me. I feel that perhaps because of the higher velocity, heavier airsoft BBs may perform better.

Comments: This latest KWC M&P 40 airsoft replica is based on Smith & Wesson’s Ported Performance Centre pistol series, engineered for competitive shooters. This pistol has several improved features over the previous M&P models, including an extended ported barrel and a more aggressive grip texture. Not only does it look just like the real thing, this gun feels and fires like a real Smith & Wesson with its powerful blowback system. The adjustable white dot sights, interchangeable palmswell segments, and tactical accessory rail allow you to customize your pistol setup anyway you like.

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...
