I think he may be confusing the free weapons you get for a radio tower on the second island with signature weapons, because there's no more signature weapon markers in my handbook (aside from the Bushman) and I believe there's only one weapon for each category.

i know i went for an all loud teams using the 1911 in pink of course XD, the 1887 shotgun and the anti-material rifle, also the bow but only because i refuse to use an automatic weapon and because its awesome XD
didnt require rushing, found main story relatively short. only thing i didnt really touch was the blue exclamation point side missions and 'wanted dead' missions which im doing now. did all towers, outposts and crafting - 15 hours gameplay.
yeah, you rushed.
