I bought a 669 in '85 or '86. It was stainless and aluminum. I carried it some but didn't really care for it. Grip was like holding a 2x4 (and I wear XL gloves). Mine wasn't very accurate --- or maybe I just couldn't shoot it well with the terrible sights. I WILL say it was always reliable with the 115 grain Silvertips that I fed it -- never a problem.

My 3913LS is a TOTALLY different pistol. I like it very much and it's accurate.
