It's an N frame, the same frame as used in the .41 and .44 magnum, much heavier bullets, higher pressure,recoil etc. Nothing wrong with a Ruger, but a 28 will handle anything you want to feed it, barring a double charge of Bulls Eye or the like...might even survive that but I wouldn't try it. But I don't play with rattle snakes, or pick fights with red headed women either...
