Although the MAG-AD9 works with many aftermarket magazines, Stern Defense recommends using post 2004 square notch, Glock OEM magazines, as these will provide the best fit and function.
Not compatible with PSA Hybrid or Foxtrot Mike bolts. This is due to the lug which strips a round off of the magazine being .035 of an inch further from center-line as compared to other bolt systems.
