Well, parts can be gotten from PPS but the problem is how expensive they are compared to phantom parts. The real deciding factor here should be the performance. A phantom will blow a way a stock P-68sc any day performance-wise. If you're REALLY wanting a vintage gun and don't care about how it performs, get the P-68.
