I had read elswhere about the 500 unplated 51's. For some reason Track only wanted $400 for it, no box. All serial #s match and it has them out the yazoo.
Comparing it to my Signature Series there are differences. The address line on the barrel can be read while in my right hand while the Sig series is reversed. The 2nd Gen also has a noticable smaller trigger guard and shorter trigger. Also the front sight is smaller on the 2nd and the bottom of the grips have a bevel as opposed to flat on the Sig.
While my Sig series has really been no problem, I got it new in '84 or so (#297xx) I already like the 2nd Gen better.
It should go well with my Parker-Hale Musketoon or my full stock Hawken.
