As a matter of fact, the Cougar was DESIGNED around the 40 S&W cartridge. The 9mm and 45 offerings came later.
I like my 9mm Cougar as much as you (like yours). It is truly a superb handgun. I've never had a single malfunction....and the darn thing is as accurate as anyone could ever want it to be. The Cougar is my favorite - and is definitely the best handgun purchase I've made yet, even in comparison with my Sig Sauer and my S&W revolver (two guns which I also like about as much as I possibly can).
