FPS: 312+ fps There are very few 4.5mm Steel BB guns made by KJWorks and it seems that ASG as far as I know is the only distributer that has teamed up with KJWork to have them make some of their guns, I reviewed the ASG CZ 75 which is another ASG/KJWorks distributer 4.5mm CO2 Blowback Pistol. I don't even think you can get the 4.5mm Steel BB shooting version direct from KJWork? What I love most of all about the ASG X9 Classic Beretta M9 CO2 Blowback 4.5mm BB Pistol is that it is made by KJWorks since there are already a lot of Beretta M9's and Mod. 92's already out there but if I could only have one it would probably be the ASG X9 Classsic!
