VA - Police officer gun "malfunctions"

[The Annoyed Man]

Per Andy's article above

Mason said the gun had fired correctly "on a number of occasions" at biannual qualifications at the county's firing range, and subsequently fired correctly during tests after the Monday incident.

So sounds like he failed to replace te firing pin spring with a new one, and the old one may be weak.

Either that or the pin was removed and put back without the spring. I used to own a USP Compact .40 and the only reason I sold it was to get out from under the caliber. But I otherwise loved the gun and it was extremely reliable and shot well. I wouldn't mind owning another one today in either 9mm or .45. Great guns.
