Excellent input and opinions.......all is greatly appreciated !!!
It's kinda a mixed pot, much like when I posed the ? to friends both @ the GC and in general.
I don't want to have this come across as a contradiction to my original post, but I agree I have no qualms with either caliber "getting the job done" as a SD round.
I guess I'm just trying to find more and more opinions and input to help justify my being partial to the .357 sig and thus the additional costs associated with staying in the current configuration and not making the swap, but I very much like the opinions/and pro's-con's that such a large group of gun owners can provide insight on
I've found (at least in my circles) those whom I'd trust to shoot their reloads all kinda share the concerns/opinion that "scooter123" spoke of in his reply to this thread when it comes to reloading that caliber.

Still looking forward to more input and opinions on this issue.
Again my thanks to all whom have provided.
