YankeeBluejeans's Review of Stern Defense MAG-ADMP9&40/P320 AR-15 M&P 9mm/.40 Magazine Conversion Adapter
It's a nicely made adapter but very expensive for what it is. Perhaps the premium price is commanded by the best product in the market? Sure, if it works!
Had immediate issues with Foxtrot Mike FM-9 upper. The bolt would not close into battery. After some research, found this to be an issue but none of the sales info mentioned it. It was a bad surprise at the end of a highly anticipated build. I could send the bolt in for modification but then the FM warranty might void.
