Sorry for the late update to the thread, folks. I ended up keeping the original Model 469 last year, but my cataract surgery that I had soon after I made the original post affected my near-focus vision enough that I couldn't see the sights that well and in my disappointment I ended up selling it. In retrospect I should've gone for the 6904 as it would have had easier to see sights.

There is a happy ending though! I did miss the 469, though—I have a soft spot for the design. Just this week picked up a replacement at a great price—it's in better shape than the one I sold. I might add some fluorescent orange to the dull yellow front sight to help me pick it up. I can't wait to get it out to the range!
