Hi, im choosing my first gun. Desided to go for a nice .22 rimfire for target shooting. I was interested in buying a Cz, but i am not sure wich one to get. Have around 500$ to spend, herd that for that money i can get a good one. I've been eyeing out the 452 varmint and the 455 lux. Witch one is more accurate? Any + or - for any of em? How about the 455 american? I'm thinking of buying optics so no open sights is no problem.
