Blowback pistols are obviously more expensive than non-blowback pistols. On the other hand non-blowback pistols generally have a higher fps and are alot cheaper. It seems that they can use CO2 with less damage or wear and tear to the gun. They seem harder to clean and it seems as though alot of them have internal magazines which are a bit annoying to load. Blowback pistols are obviously easier to load and easier to clean, however it seems as though alot of guns have atleast one problem. That problem could be with a leaking or a slide that doesn't go back all the way. Blowback pistols ALWAYS seem like they have a leaky mag problem and are gas whores, while non-blowback pistols are extremely gas efficient and there mags never leak.
Yes
If you are talking about a gas blowback m4, then yes. Green Gas, Top Gas, and propane are all pretty much the same thing and will give you about the same fps. HFC134a (or you can use duster gas) is a much weaker gas, which might not even work in your gun because it might not have enough power to cycle the bolt. If it does work, HFC134a will give much lower fps.
General rule of thumb is buy the best you can afford for what it is you want to do (target shooting, hunting, display, collect, etc..)
Unless it is electric.
.... That is why they are called GAS blowback guns. and since you even asked, i feel it important to tell you that they do not mean gasoline. they mean Green Gas, propane, or Co2
A blowback airsoft gun, is a co2 or gas powered airsoft gun where the slide on the top of the gun moves back when fired. Some people like these guns because they look cool when fired, however they use more co2 or gas.
