The PSA Micro Dagger mags are back in stock. I bought 2 to try. Keeping the OEM mag release and therefore being able to keep my stash of OEM mags around for training is very appealing to me. I never got the Shield mags due to rare but real reports of issues. Hoping the polymer portion of the PSA mags allows a better fit and tolerance from gun to gun than the Shields, but also PSA is cheap. Has anyone tested these yet?
