One of the things that I love about S&W Revolvers is that it only takes one screw to remove and replace a set of grips. I play musical grips with my guns regularly.
Factory grips can be nice (there are also a lot of ugly factory grips out there), but there are a also lot of nice aftermarket grips out there. My advice - find something you like and can afford and put them on your gun. Keep your eyes open and if you find something that you like better, buy them and put them on your gun. And if you find some grips that you love, but don't yet have a gun for them, buy the grips anyway and then start looking for a gun to put them on - that's what I did with these J-frame Keith Brown Ropers:
I love collecting S&Ws and the grips (or stocks) that go on them.
Good luck and all the best!
