I know you said semi but I just wanted to show you what I picked up one time when looking for a 22LR semi! It's loads of fun and doesn't cost hardly shiit! I'm looking for a semi right now also. Good luck with your search Sir!
I have a Volquartsen I'm parting with. Great accurate and reliable pistol. I bought it to shoot steel challenge matches with, but I recently found a CZ Kadet kit for my Model 75 so I've been using that instead because it feels and points the same as my center-fire 75 I compete with so the Volquartsen isn't getting any use.
