I've got an XO and I love it. I actually had a colt as well and my brother begged me to sell him one and it pained me to give up the colt, but there was no way I was letting the sig out of my hands. It just handles that well. Sometimes I cry into my pillow at night thinking about my long lost colt, but when I do, I'm hugging my sig tight and thankful I didn't make the wrong choice. the Sig is nice and tight, very accurate and has a great look to it. I changed out the grips I should note. The ones it comes with were just too aggressive for me, but you might like them.
