My initial thought is P30S all the way. They're bomb-proof.
That said, in fairness, I decided to at least look up the specs of each again. I was surprised to see the
92X Compact is only ~1.1oz heavier! Now the full size 92 is ~6.5oz heavier, which certainly isn't nothing but, the compact is quite surprising. Damnit, that means I'm going to have to add one to "the list" to pick up in the future (it was inevitable).
I think when I do, I'll probably try to find the discontinued
non-rail frame model for no other reason than the aesthetics.
For the P30, I'd strongly recommend the
GG short reset kit (that's the safety-specific version) and, in particular, the
GG straight trigger. Both of those go a long way towards eliminating much of the flex and grit in the pull. If it was me and I was already modding it, I'd also do the nickel sear spring (#215691) and possibly the lighter firing pin block spring (#209296).
