Like as a sidearm? I mean, read the discriptions and reviews! They seem like guns from heaven. There both WG CO2 1911s, and supposedly go up to 500fps, but people say it's more likely 420fps. The un-smart part is that people say it makes the opponent bleed at 40ft. Ones $40, and the others $75. They would be a secondary to a ~350-410fps AEG, even though people say they're great primary weapons.
