ive got 2 452's...one in 17hm2 and the other in 22lr....and also a 455 fs in 22lr. They are all excellent guns for the money...the triggers can easily be reworked with an ace spring or a yo dave kit from ebay. All of mine are super accurate, i think youd have to spend a lot more money (think cooper or annie) to get something that outshoots them consistently.
