It feels just right on the hand, not to big not to small. Slide was very smooth trigger was a bit heavier than the vp9. Out of the VP the FN and the SK, surprising the SK felt the thickest in hand. The 509 is a real sleeper in my opinion. Was actually surprised that he had both the 509 and the SK in already. If I hadn't waited months for the p10, or if I had the extra 500,I would have walked out with both.
