I have the one installed by Zastava and haven't had any issues with it. I have seen complaints about the other types.
From what I have been reading only the Zastava Tokarev M57A has a factory safety which was on the slide, if you is not 57A, Would you mind posting a picture of the safety yours has? Thanks for the info
