Since the VP9 hit the market in 2014, there has been nothing but solid reviews, great results, and confident owners. HK's decision to move back into the striker-fire business suprised some. What HK owners appreciated was the fact that HK decided to build the VP9 on the framework and blueprints of the P30. The trigger offers a much different feel, surely a positive for the VP9. To everyone's benefit the VP9 takes full advantage of its design and uses the P30 magazines. The magazines are available in both 10rd and 15rd options for 9mm.
