Designed and originally manufactured by Beretta (The Beretta 8000). Stoeger is owned by Benelli, who, in turn is owned by Beretta.
The Cougar is manufactured in Turkey with the same process and on the same machines as it was when produced by Beretta. Beretta transferred the Cougar to Stoeger when they started manufacturing the PX series.
When produced by Beretta, the Cougar was adopted by some PDs...including the LAPD (Cougar 8045 LAPD).
All of that being said, not having owned/fired one, I would not be afraid to own/trust one.
Dangit!! I hate when I get pancake mix in my gun!!+1 To everything
I've not heard anything bad about them, and the few people I've met who own them or who have shot them say they're a blast and accurate.
They're been on a couple shooting shows for little segments, mostly about testing. I beleive one test was 130 rounds straight, rapid fire, to see how the heat affected accuracy. There was no jams but the patterns started moving up after 100 rounds straight.
The other test was opening the gun and putting pancake mix in. They got it to fire, but not cycle. But everything was coated, springs, trigger mechanism, etc.
