I bought two SA Prodigy mags to try in my Stacatto P Duo and both ran 100% perfect. SA has Duramag making their mags which evidently is a good thing. They are cheaper than Stacatto mags and ran great. Stacatto mags are hard to find and these are readily available so if you need one, buy with confidence.

I only tried a sample of two, but both ran great. My friend ran his in a C2 and had no issues.
