I've got a Star 30 MI, that I purchased new back around 1988. I actually shot it so much I shot the barrel out, sent it back and they replaced the barrel for me. That must have been around 1993 or so.

I purchased an extra factory mag back during the Clinton administration, paid $40 back then.

I have a few of the 59 series mags that I obtained to use in that Star, but I never got around to seeing if they fit. I don't shoot it as much as I used to, and I suppose I didn't feel the need.
