Sorry about not get'n back sooner, actualy just forgot.
I wanted .22 auto to hunt with & tried every one & could get my fat fingers on & they all had crummy triggers on them,the only one that had the after market support (and options for a better trigger) was the 10-22, but in all honesty I'd rather shoot a Marlin model 60, & have since found a fix for that trigger also, so the 10-22 mite get sold.
I'm a CZ fan also but even the auto they produce has a sloppy trigger & not much for a fix for it, but thers sevral fixes for the 452 , just wait'n on a good deal on the rite scope & its ready for fall.
