Perfecta is a brand made by Fiocchi.

Each manufacturer makes their own decisions on the components they use in their ammunition. While they must all conform to certain parameters to get their product to work, the primer, powder, hardness of the lead, thickness of the jacket, amount of crimp and even details of the cases (note the rounded outer edge of the case head frequently found on R-P headstamp 9mm brass) all of which can affect feed and function in a particular gun.

This is one of the reasons I load (essentially) everything I shoot. I can work up a load that works well in each of the guns I use them with and then I never have to worry about whether the round is loaded with the equivalent of HP-38 or Red Dot, whether the primer is sensitive or not, or the hardness of the lead in the bullet. Once I get a load fully worked up, it becomes like an Apple product, "It just works" and that's what you have to have if you're going to rely on that gun to keep you alive or put food on the table.
