We've all seen less than stellar reports of problems with VP9, I can think of a few off the top of my head....
Firing Pin Drops on Impact to Butt of Pistol (no discharge)
Water in Firing Pin Channel Causing Failures
Very Sensitive To Environmental Contamination
Is there anybody here who can share first hand knowledge of what has been found in large scale testing? It seems there should be more of these in duty holsters if there were not problems, considering H&K designs for LE/MIL exclusively and doesn't consider civilians their main focus.
