This is incorrect, at least for certain weapons I've played with like Talon. Talon can proc after 1 auto or it can take up to 15 autos (or even more).
Adding a set amount of autos before it procs might make the game more skill based (say a weapon procs every 5 or 10 autos exactly), but right now it's totally random, probably based on a percentage (like 15%, as Cinco has stated is the % 2h weapons can proc).
