Got probably 3-400 rds thru my TX-22. Runs great. Just have to make sure you load the mags correctly, otherwise you get rim lock with the ammo.
Comes threaded and has a mag loading helper as well to save your thumbs.
Mags are scarce right now. I think these things are selling pretty briskly.
This is what I'm wanting to tryout next. If i don't like it my next would be the Tx-22, SR22 and a GSG .22. Guy showed me his one day with a can on it and it had such a great feel.
