[Karate]

Who manufactured the Sig Zipper back mags....there are 2 different versions one with a big zipper one with a smaller zipper...were any of the blued like the ones Mecgar made for Sig

All the zipper backs I have are parkerized I believe. Not sure who actually made them for SIG or whether they were in house. I've never seen a Mec Gar marked zipper back though.

JP Sauer, I believe, manufactures the zipper backs. There are several types of factory sig mags - the zipper back and the dove tail.
