An HK VP9 costs more than a Glock 19/17/whatever. That's just he way it is. Every now and then somebody might get a screaming good deal on a VP9, a deal most people can't get, but that doesn't change that the HK costs more than the Glock. That's...just the way it is.
MY experience is that I want to put very specific night sights on a pistol so I don't ever buy them with the factory stuff, making the LE edition or equivalent a bad buy
But to bring us back to the beginning, a VP9 LE is not cheaper than a 9mm Glock with night sights and three mags. And once yous tart adding more magazines...forget about it
