It is not recommended to make airsoft pistols, since they would be ineffective and partially dangerous to make ( eg the spring not secured well and hitting you in the eye), however, most spring airsoft pistol cost around 20 UD which is really cheap. Good spring pistols all come from Tokyo Marui, a renowned Japanese airsoft brand that can be found in many stores and online shops in the US or worldwide.
The internet. There are many online Airsoft stores that sell Tokyo Marui guns.
If you are looking for a spring pistol, go for any Tokyo Marui High Grade Hop Up models. If you are looking for an AEG, go for the Tokyo Marui G36c.
