Next time I get my wife to the range I plan on having her shoot her Glock 42 and my P365. I'm hoping she shoots the Sig better, because it's really close to the same size as the G42, but will hold 10rds of 9mm in a flush mag versus 6rds of .380 in the 42.
If I were in the market for a subcompact, I think that would be the one.
