For your consideration are 15 round USGI M1 Carbine magazines. During WWII the 10 prime M1 Carbine manufacturers were also required to furnish 15rd magazines to the government along with their carbines. To my knowledge, not a single carbine manufacture actually produced magazines in house. They all subcontracted the manufacture of their magazines. It is interesting to note that many of the 10 prime M1 Carbine manufacturers actually subcontracted with the exact same provider; however, the magazines were marked specifically for the prime carbine contractor. The following link will provide you with the appropriate codes for each subcontractor and the respective prime carbine manufacturer. M1 Carbine 15 rnd Magazines The government also contracted directly with companies other than the 10 prime carbine manufactures to provide 15rd magazines. What I have available are: Sagnaw S’G’ ---- 2 Underwood --- -2 Quality Hardware --- 2 Inland ---- 4 Winchester ---- 4 Standard Products --- 1 Sagnaw SG ----1 IBM ----1 NPM ----1 MISC ----9 All the WWII manufactured magazines had a “blued” finish. According, these magazines show wear but I will guarantee that all are very serviceable. Money back if not satisfied. $15 per magazine FTF in Byram Area or will ship on your dime. *NOTE: Those MSGO Members that have purchased a carbine from me will have priority for purchase. For those who purchased carbines in the "Luck of the Draw" - you will receive 1 magazine specific for your carbine maker along with the carbine.
