just picked up a new 22/45 from the gun shop a few hours ago it is the new model that has the threaded barrel but still maintains iron sights anyways i diddnt toy around with it too much at the shop but when i got home i man handled the hell out of it and the things that stood out to me was how rough the slide release is and how much force it takes to cycle the slide after the trigger has been pulled admittedly the last ruger mark anything i played around with let alone shot was a early 90's mark II goverment model and it was silky smooth all the way around as a youngster i never had any problems cycling the slide on that is it just me or has the attention to detail and craftsmanship died
