This has got to be one of the most asked questions when people are trying to decide on which CO2 BB Pistol they want to buy. The reality is that most non blowback CO2 BB pistols will generally shoot just over 400 fps and most blowback BB pistols will shoot around 350 fps. Some may shoot a little faster and some may shoot a little slower. My question is this… What difference will it make if you are shooting a BB at 350 fps versus say 450 fps? I honesty think that some people believe that if they purchase a CO2 BB pistol that shoots a whopping 499 fps, then they have acquired a deadly weapon with crazy stopping power. The truth of the matter is that even a 500 fps BB gun is still not suitable for even small pest control or hunting, you would only be causing the animal to suffer if you shot it with such a lower powered airgun. So using an air pistol for any kind of personal protection on human sized targets is completely out off the question.
