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.
What are the differences between the Duramag (mags) and Staccato mags? Metal finish is obviously one. Plastic versus aluminum basepads and the latest Staccato mags have a stronger spring. Is that pretty much it?
My Gen 1 Stacatto springs were weak that I bought and are silver. Stacatto sent me new longer / stronger springs and followers to remedy those shitty mags. The Gen 2 mags I bought with gun were perfect.
The springs on the SA mags have powerful springs in my estimation. Duramag has done a very nice job IMHO, but time will tell. I don’t see any obvious weak links.
