When I had an FFL back in the mid-'80s, I ordered a surplus HK-PS9 that had been used by the Koblenz, Germany PD. Found the ad in Shotgun News; cost $245. That was a sweet shooting and accurate pistol. Safety didn't work at all and I couldn't find anyone interested in repairing it 30 years ago, so I sold it. Funny how perspective changes over time regarding safeties, LOL. One of the few firearms I regret getting rid of.
