TX22 has lots of positive reviews online, I almost got one but bought a m9 22 instead, because they are easier to find a holster...
I have been having a little trouble finding a holster. I have an older Uncle Mike's sidekick size 21 that fits my Steyr M9 which also fit the TX22, but I don't think they sell this exact one any more. I also saw a youtube video where some said a Glock kydex holster fit the TX 22 but I don't know an exact model so I wouldn't trust this...
I ended up going with S&W 22 compact !
Best 22LS semi-auto I ever fired (by far) is/was the M&P22 (not the compact - didn't like the trigger). Walther made these for S&W and they are/were smooth as butter. Eat anything and so easy to rack a round.
