The grip safety? What does that do for you out of curiousity?
Size of a carry gun is total a personal thing. It depends on your build the clothes you wear and how comfortable you are carrying your weapon and were and which style you plan to carry. I am 5-10 about 190 to 195 pounds. I carry at 4 oclock IWB everyday. I wear Dockers and golf shirts to jeans and Hockey jerseys. I carry a couple guns one of which is the CZ P-01 I do not own the 07 I like a heavier gun. I do also have a Kahr I carry when I am wearing very summer style clothes. I personally don't think the P-07 is too big to carry. I would carry a FN40 with the correct holster and clothing. Holsters are as important to carrying as the weapon......my advice is get a good quality holster. Cheap ones are cheap, and inexpensive and will hold a gun and are cheap. Good holsters will hide your gun, give you easy access to it, and the ablity to reholster with one hand and will keep it secure in most every situation. They are well worth the money. Get a good gun that you can be comfortable with. Your carry gun depends so much on you and the way you do what you do and what you like that it has to be your decision. Asking others if they can make it work is a good idea, it can work with a P-07. Good luck with what ever choice you make. Practice with the gun and practice with the holster. The more fimiliar you are with your equipment, the better it will work for you.
