Weird; I've owned five Redhawks (admittedly, only one chambered for 44Magnum, bought new) and all had decent DA feel, with the 44 being the most stellar. In fact, its DA trigger feel is good enough to be compared with any fine trigger.
(and the others were none 'bad').
No trigger work, just the way it came from its box......
For YOURS, first ensure it is assembled correctly, then lubricate it using BreaklFree CLP.
Better?
