Nice VP9sk. I picked up 2 additional HK extended mags for my P30SK, one more 13 rounder and one 15 rounder since they were on deep discount. I am surprised at the small size of the 15 round mag. These mags completely change the possibilities for the SK model’s I think. That now gives me 7 mags specifically for the SK, plus the multitude of P30 mags that fit too. Feeling more supplied now…..
