alwslate, Cheetahs come in both double and single stack. If it is an 84 model it has a double stack magazine, the 83 and 85 models are single stack. Neither have the pop-up barrel. I have had a Beretta 84 since the 80s and it is a joy to shoot. Since it is made out of metal, with its weight there is very little recoil, way less than my 9mm Shield. Back then there were very few handguns with 13 round magazines so it was great to have the larger capacity in a small weapon. I have large hands and the larger grip fit me perfectly. Mine is blued and has great polished wooden grips. It is one of my favorite handguns and I only shoot it occasionly since I want to keep it nice. It is very accurate with its 3.81" barrel despite what some have indicated. The design was good enough for Browning to also make a copy of this model for years. It's design is kind of like a smaller version of the Beretta 92 which has been in military service for years. Bottom line, it's a great gun, try one and you might love it. Regards, Elliot45
