The first reaction I had when I picked mine up was: “this is exactly what the real P226 feels like”! Weight, balance, grip girth, etc… in fact, other than the sights it is almost exactly like a Sig (minus high end finish), but that is until you try pulling the double action trigger! Mine was about 14 or 15 lbs in DA and quite rough, and the single action was about 5.5lbs. The sights aren’t bad, but nowhere near the sights on real Sigs.
I have only 300 rounds through it, 100 Win USA 165gr and 200 reloads with 150gr and 180gr bullets. It hasn’t jammed but once, on the third mag while shooting weak handed (I honestly limpwristed it). I cleaned up the trigger a little bit and SA is now 4 lbs and reasonably clean. DA is still too heavy.
One thing I don’t like is that it ejects empties all over the place, including my head and face. I ended up filing an angle to the ejector’s face, like on Sigs (it was originally square faced) and it helped a bit, but not much. I also put some more tension on the extractor (about as much as on my 1911), because it just didn’t hold the brass at all, it just floated underneath the claw. However, I think the reason might just be a weak recoil spring. The Sig P226 in .40 S&W is supposed to have a 20lb recoil spring, but it is much, much easier to retract the slide on my NP58 than it is on my Para P14-45, which has only a 16lb recoil spring with over 4,500 rounds on it. So I’m planning on putting in either a 20lb or 22lb recoil spring and see what happens.
All in all, I am very happy with this gun. The fit and finish is even close to some Sigs I’ve seen, and certainly much better than I would expect from a 350$ gun. And, as everybody else seem to agree, the plastic grips just have to go.
