How to tell between SW76 and MK76 mag

[johnrigby]

I know the MK760 mags are unmarked, are the SW76 marked

[KML]

S&W factory mags are marked " 9mm CTG" on the bottom.
I have not had any luck finding a good factory MK760 mag,that will run in my S&W 76.The Soumi mags are much better than the MK760,and in general work in MK760's with no modifications and lock up better in the mag well of theMK760.In the S&W 76 you may have to lighty sand the front pad to get them to fit.Plus you can find them for $9.99,Tapco had them for $5.99 if you ordered more than 10 about a year ago.
