I've always wanted one of those.
Star made great pistols.
I regret selling my BM to a friend.
I've owned 2 M45 Firestars. Sold one to buy a Maadi AK (that I ended up selling).
Bought the second M45 to replace my original one.
Would love to have a Megastar in 10mm and .45, and another BM.
Always wanted a 30M.

The only guns that I can actually say I know for a fact take 59 series mags without alteration are the Daewoo DP51/Lionheart series, and the Marlin Camp Carbine. IIRC, the Kel-Tec P11 takes them, too, but I've never tried it.

I feel your pain on Star mags.
If I'd never sold my original M45, I'd have more than two mags for it. They are not cheap or abundant.
