I got my NP 58 around Christmas. I'll rate it 9 out of 10. The finish is good and Sig copy from Nork is not bad at all. I have a Sig Equinox in .40, and I try to switch the slide but doesn't work. However, the mag and barrel are interchangeable. For accuracy, it shoot as good as my Sig Equinox. Of course there are things that you don't like. The double action is terribly long and heavy. Another thing is, it FTF on the last round because of the weak mag spring. I switch to the Sig factory mag and the problem disappear. Overall impression: excellent for a .40 semi at $360. I love good and cheap gun!
