I've heard of some challenge saves with 0 arrests or 0 deaths so i wanted to make something similar too. So i did.
My save is with 100% completion, all kills are headshots (which means my kill count and headshot count are identical) with 100% accuracy and 100% manual aim. No cheats of course.
The main missions were hard because basically whenever i missed a shot or killed an enemy without a headshot, i had to start that mission all over again.
Pigeons were a pain in the ass too because the game didn't count a pigeon as a target and it was a missed shot. So i had to improvise with molotovs and even Annihilator for those hard to reach pigeons.
But i'm satisfied with the result. This save also includes Bernie's Infernus as well as Brucie's yellow Comet and Playboy's yellow Patriot.
The save can be found Here
After downloading and extracting the file create a new folder called "PS3". In this folder create another folder called "SAVEDATA". And finally in this folder copy the one from file you downloaded called "BLES00229SGTA411". Only after you have done this the save file will work.
The save is called "No.1" and not "Story complete" because it was the last mission i did after completing the main story line.
