Friend gave me a bunch of M9 magazines, and these were mixed in. I suspect they are for the M11, a Sig P228, but would like a second opionion. They are 13-RD and appear to be 9mm (see pic) marked with Sig Sauer inlaid on the left side.
If this isnt the proper section or not appropriate please delete, thanks.
The magazines in question are without a doubt for the P228\M11 in 9mm. Sig made magzines will have a small circular stamp with three ‘S’ in the circle like spokes on a wheel. Mec-Gar made magazines don’t have this stamp. Either way they are excelent magazines, and pre ban as well for those states that still have an AWB.
