I had one, but someone else wanted it more than I did. Now I'm thinking about another, but I still have 5 new in the package 30-round magazines from the Scorpion 1 and don't know if they will work with the 3+ now available. I haven't been able to find a definitive answer anywhere, so just wondering if someone knows. CZ says the new 3+ magazines are backward compatible, but they pointedly do not say if the old ones are forward compatible.
