S&W web specs for M41

Smith's site has some really oddball numbers for M41 weights. 5.5" is listed at 69.41 oz, 7" 67.2 oz, 5.5" PC 75.81 oz.

My 5.5" M41 weighs 48.76 oz. with no magazine, no rear sight, Weaver #62 aluminum base, 1" UltraDot w/factory rings, and Herret National grips with the extra wood under the palm shelf trimmed off. 

Hope this helps with any confusion that may be incurred during web research.
