Well, you want to hollowpoint anything you're intending to use for defense, period. And more importantly you want to get it on target. A .380 in center of mass is more likely to stop someone than a .40 in the shoulder. A 9mm 115gr JHP is going to do way more than a .40 180gr FMJ. So many things factor in beyond just caliber. Like, how you react when the sh*t hits the fan.
That said, I went .40 because I knew there were some excellent .40 compacts out there, and if it's a little bit better, it's a little bit better (yes, I do intend to carry it). Still I wouldn't run down the 9mm too hard. Properly loaded it can be very reliable as a defense round. I almost went with a subcompact actually...but the three-finger grip is what put me off. If I don't like shooting it at the range I'm not going to shoot it...and a 180 grain .40 on a 3 finger grip and a 3 inch barrel is not going to be fun for me.
I paid about $100 less than MSRP. I shopped around on gunbroker.com, took my best price (on a new gun) to my local guy, and let him upcharge me a bit (basically he got to keep what I would have paid as a transfer fee for profit). To be nice he tossed in a Gold Membership at his range for a year.
If you are looking for a 1911 style now is a great time to do it. There are a sh*t ton of new models out this year for the centennial - some cheap, others 4 figures. Kimber is in the latter category for the most part, but they sure make beautiful handguns.
