It’s big.
It used to be $400 for 3 mags, holster, and ns.
The name is the deprecation year of the model from service.
None of this makes it bad.
PX4 or P99as would be higher on my list for da/sa in that price range where HK ups or p30 or p2000 might be first is price were meaningless/on the approved list. PX4 has a lot going for it though. P99 might be cheapest while best trigger of any.
Nothing terrible about it. Nothing stands out either.
