CO2 ?

To the best of my knowledge, no one in 10m Corner has a bulk fill CO2 gun.

I've certainly no first hand experience of them but the norm is to refill them from a repurposed fire extinguisher. There's a bit of a process involved but I'd imagine it's not too bad and you could probably get it refilled from one of the local industrial gas suppliers.

From what I've gathered, CO2 target guns have very nice shooting manners but fell out of vogue when a world class shooter had a bad day, blamed his gun, switched to PCP power and everyone else followed suit.

As for the pistol in question, it's an FWB so it's exquisite by default. It won't suffer from the cool down problems that affect fast fire CO2 fun guns running 12g carts and will be effectively self regulating. It is old though and parts/seals may be a problem.

I wouldn't mind a go with one and think I'd like one in my collection but really couldn't advise on whether it's viable as a sole 10m pistol.
