Are all real Colt 1911 factory magazines marked on the floor plate with the Colt pony? I have a chance to buy 23 1911 magazines which I am told are original factory Colt magazines but the floor plate is marked COLT 45 AUTO without the Colt pony. Is this the real factory mag or are they fake? BTW these are blued 8 round mags and are for sale at a gunshop near me for $15 each. Could be a good deal on factory mag or ripoff with fakes.
