I find some of the ads humorous as to asking prices/round counts and claims of BNIB etc but hey, it is their stuff. They can ask what they want for it.
WTS - VP9 - NNIB (box available, but was used for a diorama, still sticky) - round count low (enough to know the gun was mocking me at the range) - a few dings (after the mocking was discovered, it was thrown into the gravel and stomped on) - $530 firm with 2 magazines, $630 with 6 magazines (all magazines were used at least once to verify mocking, if that helps with round count estimation).
