Congratulations! My P-88C is the most accurate pistol I own. Mine can also be a little finicky with the bullets. If seated very long or having a wde ogive, the bullets will hit the pronounced leade of the rifling and prevent the slide from closing. I get best feeding with minimal-ogive bullets like TCs or spire points. I think this was only a problem with some P-88Cs; yours might be fine.
