I own a Beretta Cougar 9mm.Very well made pistol.It is double and single action with decocker.It does reduce muzzle climbed with the rotating barelStoeger Cougar ?(Beretta moved the production of the Cougar to Stoeger).
It's said that the rotating barrel reduces muzzle rise and are an excellent pistol for the money..l've only inspected one but the quality seemed excellent.
