I just purchased this gun today... brought it home and took it apart.. wow.. it took me a half hour to put it back together.. my question is...when its all put together and the slide is locked and you pull the trigger as far back as possible.. do you get a tiny little resistance.. like its rubbing ?? because on my cz po1 its smooth as a hot knife going through butter...im just worried i didnt put it back together 100%..
