Is the 1377 and 1322 barrel outer diamter the same size?

So, for a while i was making a costom 1377 but i want to move those changes to a 1322 because i want to convert to .22 because it hits harder. I dont want to buy a new steel breech,though. My 1377 steel brech loads .22 pellets fine, but i saw a .177 and a .22 version of it, so i was wondering if there is any size diffrences that would cause incompatibility.

Yes 1377 and 1322 barrels are the same 7/16 OD. Also the breeches are the same, only difference between is the bolt probes.

is the probe just bigger or something? i mean if worst comes to worst i could just take it off the stock breech, right?

Yes they are shaped different, and use a slightly bigger o ring. You can use the stock one but you have to drill out the crimp on the handle and pull it out. Then tap it for 8-32. Then you can use the handle from the steel breech kit on it.

Or you can have a .22 bolt made from one of the guys here.... Ive seen some nice ones and the price is very fair....
