I got a good price on a used Rossi Model 720 .44 Special, but the reason I got the good price was because the rear sights are missing. I thought I'd be able to get new ones, thus the good deal would remain a good deal. Imagine my surprise when I discovered that Taurus, who bought most Rossi designs, doesn't support the Model 720! They referred me to an Interarms representative, who said that there are no Model 720 rear sights to be had! Now the good deal doesn't sound so good. Are there any generic sights that might fit? Any ideas would certainly be appreciated!
