If it's always the top round in the mag, then I'd look at the mag. I've had issues with fully-loaded mags, especially those designed to hold "one more round", with excessive spring pressure on the top round adversely affecting feeding; the round tends to nosedive and stump against the frame rather than feeding up and into the chamber.
Sometimes it's a bit of a tightrope walk, as you need enough spring pressure to get the last round into position, without too much pressure on the first round.
