For an HK striker gun it is greatness, compared to most striker 9mm, it is greatness right out of the box.
All my buddies who are Block fanboys spend more in 'upgrades' than they did on the pistol, easily surpassing the price of pretty much all HK handguns, save a few.
What's not to like about the VP9, LEEF? Most think the VP9 was introduced by HK to allow for a lower price point than the usual grand to get an HK, and they did a pretty good job in doing so.
I'd say go shoot your VP9, a Block, an FN, etc. then ask yourself, which is your preferred striker fired 9mm (sans mods)....
