My USP? Well I think its great...
Its 50% great name/50% great gun. When I bought it I wanted a polymer duty/military pistol. My choices were Glock, Sig, Walther, and HK.
I picked the HK alot on looks, as its comparable in quality to Sig and Glock. For longevity perhaps Sig might last abit longer, Im not sure yet.
BTW, I have several thousand rounds through my Nork 1911 and its been fine. If I can get a pic of it, ill post it. You would be surprised by the fit and finish on it. Other than adding a shock buff and changing the grips...its all stock.
