I'm interested in some good training pistols, and possibly rifles. It looks like battery is the way to go (no actual air used in modern airsoft??), but I'm just guessing based on what I've seen talked about on BlabTube. I have a decent Sig 320 air pistol, but something that doesn't need me to buy CO2 carts all the time and leave lead all over my yard has some appeal. (tracking thread)
