You will get two opinions (at least). There are folks who say don't carry a fancy gun for EDC because if you have to use it, the police will take it as evidence. You will either get it back after a long time or perhaps never. That is one reason they say not to put a lot of "bling" on it. The other thing that is said is don't get your gun modified. If you modify it some way (lighter trigger, etc.), some also say that the prosecutor, if YOU end up getting prosecuted or the plaintiff's attorney if you get sued by the person you shot, will make a big deal about how your pistol was modified.
Speaking as one whose carry gun (if I felt that I needed to carry a gun) was a P7M8, I suggest that you carry what you shoot well and are comfortable with. I had to sell the P7M8 years ago so I now carry slightly modified 365s, one with an optic. I am happy with the triggers, but if I wasn't, I wouldn't hesitate to have them worked on. When I carry a gun, I want a gun that is comfortable, modified if necessary to get it to where I can shoot it to the best of my ability. That's my advice. YMMV of course.
