The KJW MK-I is an exceptional Airsoft hand gun with optimized gas usage, portability, power and range. It is arguably by most as the most effective side-arm for outdoor environments because of the portability (it is fairly light weight and compact to be put away when operating your primary). Yet, it outputs an whopping 350~450+ FPS for the range and power you need to backup your primary. The KJW MK-I is also among the most durable pistol ever constructed with an extremely high gas efficiency.

"This thing is overall a very good pistol. Very sturdy, easy field stripping and my mags will not fall out when I have this shoved in my jeans pockets.
-Easy to take apart
-Very good gas effeicency
-hard shooting
-Long trigger pull (not a big deal)

Overall a good performing gun, not as fun as blowback but you dont burn through green gas.

"This is a great pistol! Great for the price that it is sold at as it is full metal interior and mostly metal exterior. The only con I could possibly have about this is the mag release as it is on the bottom and a little tough to get used to.

"I bought this gun from a local AZ shop and love it, but the fps makes it hard to play with. I have used it on a private field and had back to back hits from at least 50yrds away. I've had no problems with this gun as far as functionality or accuracy.

With a fresh mag and .25 bbs it was running the first shot at 550fps and dropped from there but not much.
