The 327 PC does have some attributes that the NG lacks. The Lother-Walther German made barrel with polished button rifiling (though I'm afraid I don't know what "polished button" means). The hammer and trigger are not MIM like the NG and the trigger has an overtravel stop. I'll assume the PC has a ball bearing lock up like my other PC snubs. The trench style front sight channel seems more CCW friendly (less chance to snag) than the C&S Extreme Duty sight. Lastly you get a PC tuned trigger group.
