I've had a Cougar in .40 for a year now. I like it very much. The size-to-caliber ratio seems a better fit than the 9mm version. It's a big gun, but conceals well with the right holster, etc. It took about 50 rounds to break in the magazines, but the next 800 rounds have fed flawlessly. It's very tame in the recoil dept. and should be even more so with 9mm. All in all a great gun and highly recommended, especially in .40.
