Compared to a well-equipped horse, I am female. Compared to a 6'4" 280-pound hulk, I am petite. And I'm Asian either way you look at it.
Walther P99c 9mm
Springfield XD-9/40 in 3" subcompact
The PPKs have had issues since they were in existence, and I would go no lower than a 9mm. In a small, polymer-framed pistol, no higher than .40S&W. I have personal experience with the P99c in .40S&W and XD-9 3" sub. The XD-9 was an excellent gun. The P99c was too snappy in .40S&W, but great in 9mm.
