The 6906 is a better gun. Better sights, if you like Novak’s, but more importantly the 669 has a 3-piece grip that can (not often) warp and pinch. But the one-piece wraparound grips on the 6906 are also slightly smaller in circumference, and feel less like grabbing a 2x4.Might buy it if I sell something or if it sits for a while.
