I have a 45 magazine that is marked C-S on the bottom of the floor plate and "S" on the top of the plate toe. What do those stand for? I would figure one would indicate the manufacturer but why two stamps? Thank you and a Merry Christmas.

We covered this some time ago.
Here's a link to the info: http://www.unitedforums.com/forums/gunforums/cf/Forum6/HTML/000207.html

The thinking is, the "CS" is the actual contractor's code, and the "S" stands for stainless.

I should have discribed the magazine a little better. It is blued steel which came home with a 1911A1 from WWII, so the "S" can't stand for stainless. I have other magazines from WWII & Korea that are marked with an "L" on the top lip of the floor plate. Maybe someone can recommend a good reference book that would cover this? I'm starting to get into these Colts and appreciate this Forum along with everyones help. God Bless and Merry Christmas

The combination of "S" and "C-S" markings indicate the magazine was manufactured by Scovill Mfg. Co., Waterbury, Conn., and supplied under contract to Colt during WWII. The "S" indicates the Scovill manufacturer and the "C-S" indicates that it was supplied to Colt under a sub-contract. So, originally at least, it would have been found in a Colt-made pistol.

An "L" at the top lip with no other markings would indicate a magazine made (during either World War) by M.S. Little Mfg. Co, Hartford, Conn., as a spare magazine; i.e., not necessarily supplied to a specific pistol manufacturer.

And, a Merry Christmas to you!
