The 69 is with in one ounce of the 66. I never much cared for the N frame Smiths, they were just bigger than I want to carry. Even the alloy framed one, though light in weight, were just 'bigger' than I was comfortable with.
The one gun I did like, but was not able to obtain, was the Taurus Tracker titanium 41 mag. This L-frame 44 might just find it's way to my hand latter on!!!
