I carry a Special every day. The 21 and 24 balance better than the 29. As far as use goes, I carry handguns for personal defense against man. Special level power is all that is needed, and for that matter it's just fine for the black bears that I run into in my timber.

I also get better accuracy on follow up shots with the special. The mags are fun to shoot, and I can shoot them well, but you get better, quicker follow up shots with less recoil.

Aesthetically, the 24 just looks better than the 29, the lines are more graceful and it looks less blocky.
