How do the Smith & Wesson SW99 and Walther P99 differ?
The SW99 frame, although made by Walther in Germany, has a rounded trigger guard. The shape and composition of the SW99's slide is also different. The slide and barrel of the SW99 are stainless steel and melonite-finished. The slide and barrel of the P99 are steel and tennifer-treated. The P99 is considered by most to be superior to the SW99.
