Unless I'm planning on drawing a handgun from my pocket (when an adjustable sight might snag, impeding the draw) or I have one with some historical or traditional significance where an adjustable sight might look "wrong" on it (i.e., an 1873 Colt sa revolver), I much prefer adjustable sights on all of my handguns. Imo, too much has been made of the supposed fragility of adjustables and not enough to their many advantages (easier to get a good sight picture from for aiming purposes and much easier to get the poa to conform to the poi-especially when trying different loads and bullet weights from the same gun).
In terms of having adjustables on a small frame gun with a relatively short barrel, I really like the factory adjustable sights on my S&W Model 60-4, J-frame revolver that has a 3" barrel. It makes for an ideal trail gun, imo.
