HK VP9 SK vs HK P30 SK - Mercedes vs Mercedes?

Comparing these two compact/subcompact 9mm offerings from Hecker and Koch is kinda like comparing two Mercedes Benz models. The HK VP9SK is the carry size version of the VP9. The HK P30SK is the carry size version of the HK P30. One is striker fired and one is hammer fired. The VP9 SK is the B version, named appropriately HK VP9SK-B. The P30 is officially named HK P30SK-S V3. We hope you enjoy this review!
