I was a total 1911 guy until I touched an SP101. I traded a Kimber for it and haven't regretted it a minute. Then I wanted to shoot the closest thing to it in IDPA so I sold my other 1911 to buy a GP100. I love 'em both. Some people carry the GP but I agree with the majority that it's just a little too bulky. The SP is a great carry gun.
But I have to say, I was looking for a Speed Six and just didn't find one before I ran across the SP101. From everything I hear, the Speed Six or Security Six would be a great choice too. But I do really like the no-backstrap design of the newer guns that lets me shoot the most fire-breathing Magnum loads in comfort.
[edit:] Ooh, I missed where you said you ordered the GP. It doesn't change anything except: if it seems too big & heavy for carry, then you can do the reverse of what I did -- keep the GP shoot in IDPA, steel matches etc., but get an SP101 for daily carry.
...You do shoot steel matches and/or IDPA, right?
If you don't, check it out, it's in your neighborhood someplace. It's a super fun way to keep up to speed with your defensive weapon.
