I have two CZ 452s. One is the American and the other is a full stock. Both rifles shoot very well. My wife has a 452 Lux and it is also a tack driver. My MKIII 22/45 is my favorite .22 pistol. When the pistol was scoped and shot from a rest the groups were hard to believe. I have a dot on it now but I am thinking about using the iron sights again. My S&W model 64 is a nice little gun but I have never been able to shoot it all that well.
