I should take a better picture of mine. I don't carry it, but it's one of my favorite shooters. The adjustable sights are maybe kind of "snaggy" for CC, and the plastic front sight insert is somewhat fragile. The hammer-mounted firing pin broke on mine, but with care, patience, and a small file, you can shape a S&W Model 10 version to fit. The trigger on mine is excellent and the sights are largish and easy to see. It is absurdly accurate for such a small revolver. It suits both large and small hands well. Everyone who shoots it likes it.

A local pawnshop had an example of the hammerless fixed sight version of the 720 and obviously didn't really know what it was. I got it for $250 plus tax (this was only a year or two ago). Unfortunately, the trigger is pretty stiff. Between the stiff trigger and the notch sights I don't shoot it particularly well. If I ever get around to lightening up the trigger it will be much more fun to shoot. I could see it as a carry piece, though it's pretty heavy.
The one I do carry occasionally is this shrouded Charter Arms Bulldog. It is light. I like the shrouded hammer. The trigger is pretty good. I can't shoot it like I can shoot the first 720 shown above, but I can shoot it plenty well enough for SD. I like having five rounds of 44 special in such a carry-friendly revolver.

This one was barely used at the LGS. I liked the idea of being able to practice with the easily-available and relatively inexpensive 45acp, and got a decent deal on it. Unfortunately, someone sold or traded it knowing that it had a problem. The cylinder bound itself shut after just ten or fifteen rounds of shooting. I was grateful that Charter Arms fixed it quickly and for free, even though I'd bought it used. The trigger is decent - the typical Charter Arms trigger. The little springy things that hold that rounds in the chambers are clever. Unfortunately Charter Arms doesn't offer a DOA trigger for it (last time I checked). I prefer my carry revolvers without a hammer spur, but certainly wouldn't feel unarmed with it. I don't have them both in front of me, but IIRC, it is the same size and weight as the Bulldog.
