I love my P30, and have almost no interest in owning a VP. That said I prefer DA/SA for guns I carry. I have friends with VP's.
I like the look of that trigger with the screw, I'll have to look into that. My Sig's all have 'nicer' triggers than my P30, which is factory, but there's something I love about the pistol itself it's balance, and the way I shoot with it. It is my favorite, and what I carry 9/10x I leave the house.
The big up to buying both is they take the same mags.
