Hmmm... gues you could change out the barrel but, isn't it more of a tube than a full OD barrel? And is there enough wall thickness on the rotary mag to drill it out for .22 cal? Prob not?

Can't say that I have seen one anywhere but I'm sure someone has done one at least once  :D

it appears to be a tube surrounded by polymer of somesort it is just a thought id sure like if crosman made a 22 like that i wouldnt care if i only got 20 shots per 12 gram co2

There was a thread on here about using a modified 1377 barrel in a 357. Suppose you could go that route.

Howie... why .22? With the stock 357 valve you won't even get 270 fps with a .22 pellet  :D

If you are looking to pop pests with a .22 pistol, then you will need a 2240 or an Alecto or even a Beeman P1, right?

ive got a 2240 with a bsa red green blue dot, ive made the trigger nice added the steel breech and going to keep modding to suit or getting it modded, i think id like at least a 10 inch barrel though either going to spray my grips with bed liner or get some good wood grips ive got small hands so i dont need real big target alcove grips

there have been decent results with .20 but for a .22 and the mag you will run into issues due to size and space/material of the mag and pellets
TOO many freaks and NOT enough circuses

Actually did this. :)

Turned a .22cal barrel down to fit into the 8"  "barrel". Turned the index catches off one mag, and bored one hole out to fit over the barrel. (just for looks)

Effectively a single shot...works well as I recall (haven't used it in a couple years), but I don't think it hits as hard as a stock 2240.
