I'd buy a couple. I have quite a few revolvers that are close including a 2" model 12 (barrel a little too short), 3" model 65 (a little heavier than I like), 3" model 60 (only 5 rounds), and I think an alloy 2.75-3" I frame would be perfect.

While doa and fixed sights would be ideal, I'd buy an alloy version of the current model 66 snub.
