I love my XD for the same reason I love my Chevy truck...ain't the most glamorous thing on the road but I don't feel too bad about abusing it during the course of its use and it has never and I don't believe will ever let me down. Torture tests on it are amazing, just like Glock (I think even out-Glocks the Glock, but that's considered heresy talk 'round these parts): bury it in cow manure for a year, dig it up and shoot it without cleaning it. Bury it in salty seawater/beach for a year, dig it up and shoot it without cleaning it. Ice. Snow. Dirt. Grit. Desert sand. Drive a truck over it. The thing just doesn't care. What can I say, it goes bang nicely everytime I press the trigger. That said, the little 3" sub-compact doesn't fit my hand that well, I prefer the 4" Service or 5" Tactical. But not for CCW...too "blocky" and prints too easily on my frame.
I love my Sigs (all my Sigs) for the same reason I love my BMW...ultimate firing machine. Each one has "soul", that extra something that makes a special connection with my heart and my mind...bullseye everytime at 7yrds without even hardly trying, and 4"-5" off-hand groups at 25yds are almost a no brainer, and I'm not that great of a shot, mind you.
CCW: A real nice P229, P239, or P228 (or even P232 in .380) is what I would recommend for CCW. Regular alloy, not stainless (10oz+ extra weight), is probably want you'd want, unless you went polymer SigPro SP2022 (or SP2009 or SP2340). If weight is not a big deal, then go ST...I know a lot of LOE that carry full-sized P220ST's as their duty pistol.
Range, fun, accuracy: P226R (especially ST models!).
All-around: P228 or P229 (but I know a lot of people that carry a P226R for CCW, so don't discount the P226R without checking it out first).
And if you REALLY want to get spoiled, go for a P220 "Sport"
Cheers and good luck!
