I think where the speed factor came in was with familiarity. I've been shooting Glocks exclusively for years and I think I was being more deliberate with the trigger on the P30. Another few hundred rounds and I think I could get the speed up on the P30. Unfortunately not many (if any) LGS stock P30 kydex holsters, so no HK for Sundays match.
And, by the way, thanks for the responses.
