Varies by the pistol. Normaly better than spring.
a gas or spring powered one. never electric, electric powered pistols SUCK. i would suggest a green gas luger if your looking for power, or maybe a green gas desert eagle. those are good airsoft pistols.
Revolvers ftw
NONONONO
No, however the gas lasts shorter.
If you go on Airsplat.com you can view the prices of green gas. if you want propane, you'll need a propane adapter and you can get propane tanks from sporting good stores.
if its spring pistol get a new spring or a better piston (if they even make upgraded pistons for pistols) if its gas i cant help you
Electric pistols are not powerful. If you want power, I would recommend a green gas pistol.
Yes. Gas revolvers are semi automatic, there are some spring pistols that must be re-cocked after each shot.
A gas powered airsoft gun with high fps is great but the only gas guns or snipers and pistols your need a good echo 1 electric aeg gun get iether 390 fps or higher for istnence i got a ehcko 1 x36k it go 400 fps and 140 feet that's the best you can get 140 ft is the best.go to airsoftatlanta
I was on amazon the other day and suprisingly i found a cheap one and it has deemed to be worth every penny =] hope you find one that suits you
It all depends on the strength of the spring airsoft rifle. If your refering to pistols (I will assume you are), I prefer a co2 or green-gas pistol over a springer anyday. In the big picture, springers are regarded as cheap and useless. Although the fps may be better than that of the gas, it's range (and the fact that you need to cock spring guns after every shot,) it is usually better to save up your cash and buy a good gas pistol. However, even I need to admit that some springers (i.e. quality snipers {runs you about 90-110 American dollars}) are way better than their co2 and green-gas counterparts.
On certain pistols and rifles, yes. You'd need to see if you can buy C02 mags for the certain gun you have.
