Oh, Chris, I think you started the caliber war anyway!
I am a .40 fan...actually, I am a 10mm fan, but that's another story...and the .40 S&W 180gr JHP LE rounds that I carry are more effective, round for round, than the 9mm124 gr JHP rounds available. The 10mm full power 180gr JHP are better still.
But this is the key point: a hit with a .22 beats a miss with a .44. Put another way: the caliber that YOU are comfortable and proficient shooting is the BEST choice for you.
I was trying to say that above and I think the 9mm SR is a great pistol and a great choice for the OP. I think you're saying that too.
But I don't think it's fair to say that the 9mm is a better choice for everyone. I've put tens of thousands of .40 S&W rounds through my H&K USP compact. I am very comfortable shooting it and can draw and put 3 rounds through center mass (5 ring) every time in under 2 seconds. In a compact pistol, give me the .40. But I would NOT recommend it in every case for every shooter.
A shooter has to be comfortable with the weapon, able to shoot it effectively (accurately and rapidly), and able to afford practicing with it to maintain that effectiveness. So, using that standard, both you and the OP have chosen wisely.
