I have both airsoft and Co2. The Co2 one gets about 80 shots per canister. My gun is a blow back and looks pretty sweet. I don't remember the name of it and I don't have it in front of me.....but it shoots bb's at 285 fps and will break skin from about 100 ft away, believe me, I know
my friend has one that shoots 485 fps and from 30ft away can blow clean through a stack of paper an inch thick. I tend to stay away from him when he is waving that thing around......
Actually, no, if your 285 FPS gun shoots airsoft BB's, it won't break the skin from that far away.
My m4 shoots 350 FPS, and doesn't break skin form that far away, it hurts, but I've never made anyone bleed.
Besides that, I've been shot in the face by a p90 from about 10 feet away. That goes around 285 FPS no doubt. I got hit with 3 BB's and didn't hurt for more than 30-40 seconds, and it didn't break the skin.
So I highly doubt your gun could break skin. Maybe if it shot something other than the plastic airsoft BBs.
485 FPS, that could probably do it, but anything over 400 FPS is worthless. No one wants to play in a game where you're shooting BB's that fast at them. In fact, the offical games, though I've never played one, don't allow over 400 FPS.
If you're looking into playing airsoft for fun with other people like I do (like paintball), I highly don't recommend buying a gas rifle. I have a Glock 19 as a backup weapon, and it's gas, but a pistol doesn't require all that much gas. If you have to use gas for your rifle, it's going to cost a lot of extra money, because they use up gas quickly.
So I'd go with an electric gun if you're serious about it.
If you're only going to go with a pistol though, go with gas, They're the most fun. And realistic too.
A lot of times I'll just shoot my pistol in my room for kicks. Fun to mess around with them.
