I have a Stoeger .40 S&W Cougar, plus a Taurus PT145, a Taurus PT940, A Taurus Model 441, a Taurus Model 431, a Taurus Model 85, and a Taurus PT101. The Stoeger is wonderful! Very accurate, easy to operate, perfectly reasonable to strip and clean, no malfunctions.
The Taurus revolvers are great - no trouble of any kind, sturdy, accurate, good looking.
The Taurus PT101 and PT145 had trivial problems with the magazine release's when I first got them, in that they let the magazines fall down a quarter inch or so. I figured out that the magazine releases had not been fully seated in the grip frames during assembly, and all it took was to carefully push them into place with my finger. Since I did that, in 7 years I've had no further trouble with them. They shoot straight, don't malfunction, and feel good in my hands.
The PT940 has never given me any trouble at all.
If asked to choose between them and only keep one, however, it would be the Stoeger .40 Cougar due to its accuracy and ease of shooting.
