Could be a weak powder charge, or extra drag on the underside of the slide with the 10-rd mag topped up.
I don’t have experience with 10-rd HK mags. If they’re really stiff, maybe that contributed.
In general, I trust the reliability of HK products. I’ve got close to 20,000 rounds through 4 different USP Compacts, in both .40 and 9mm, with exactly one malfunction (with purple-cased Winchester training .40 cal ammo). I know that doesn’t translate directly to the P30, but maybe it’s a helpful data point.
My thoughts - if the P30 is attractive from the familiarity and performance standpoint, put the 10-rounders aside for now and keep training with it. One malfunction is an oddity. Two is a pattern. Until you have a pattern, go with the gun you think you can be most effective with.
