On the bottom, you may notice two letters.one will be a C with a hyphen between'em.but the letter on the toe identifies the manufacturer. Look on the toe of the floorplate for a letter identification. Here is a pic from our e-zine of the Metalform baseplates by John: This magazine has their company logo in place of the 'm' used on the Colt contract mags. On a side note, Metalform sells a 1911 magazine under their own brand as well.
The second letter 's' indicates a stainless mag. These magazines are usually identified by the Colt pony on the baseplate, and a couple of letter codes that indicate the finish and the subcontractor. Please feel free to add verified codes that I may have missed and include any images you may have.Ĭolt uses or has used several subcontractors over the years. This thread is intended to be an all inclusive list of the various codes and identifying marks used on 1911 magazines. Every once in a while a member posts a message wanting to know who made their magazines.
