Interesting. So basically the P99Q is sort of a "lawyer" type harder trigger pull version of the PPQ only sold to police and military units for safety purposes?
From what I understand, Germany has strict guidelines on what pistols are even allowed to be used as police and military pistols, with parameters around trigger pull weight, length, reset distance, etc.
I'd say it's more than likely that it was made specifically to win police and military contracts that the P99 AS or PPQ could not. I don't believe the PPQ was ever meant to be a military or police pistol. Even looking at German police agencies, I believe all of them that use or used the P99, used the DAO model. The P99Q offers a pistol with a shorter trigger pull length, a lighter pull weight, and still keeps the double strike capability of the DAO P99, which is beneficial if there is a failure to return to battery issue, or the first trigger pull doesn't set off the primer.
Strange... wonder if any units over there use the actual PPQ M1 or even M2? Man, the modern Walther designations sure make for some confusion!!!
The only agency I've heard of that uses the PPQ is the Taiwan Police. Very rarely do you see a police or military agency adopt a SAO pistol lately.
