NM serial prefix, USA made parkerized Mil-Spec not the GI model. Has walnut GI repro grips, Smith & Alexander checkered arched mainspring housing. I replaced the titanium lightweight firing pin with a steel one as I was getting light primer strikes. Only a few boxes of ammo fired in this pistol. Very well made, functions very reliably. $500 local sale. Great Classic style 1911 pistol. Will ship for $25 FFL must receive from a private party with ID or make prior arrangements with me. SOLD
