The powersquirt isn't loaded, but appears to be chambered for a acid powersquirt clip. It weighs 1 kg. It is a pistol. You have no idea what it might be worth. It's a one-handed weapon requiring skill in pistols. It's a very fast weapon. It seems slightly less accurate than usual. It does slight acid damage. A skilled fighter could do a lot more damage with this. Installing a mod on this would be very easy.This weapon looks like it would kick very lightly when fired.
Note: This weapon is useless except for opening safes and certain doors.
