17-4PH is a precipitation hardening martensitic stainless steel, so be sure you have made any engineering plans such as annealing and post weld stress relief before you attempt to weld.

AMS 5803 and AMS 5825 fillers are commonly used. (My experience is with 5825)

As to which is best for you? That's above my paygrade :)

Here are some data that jive with my experience.

I cant find any filler rod that corresponse to AMS 5803 and AMS 5825. I did find this though:
Alloy 17-4 PH can be welded with filler metal ER 630 (AWS A5.9) wires.

This ER 630 filler rod should do the trick. Thanks for the help

I think my golf clubs are made of that stuff.
