    Neither of the Colt Armorer's manuals address it (that I could find anyway). In fact, they don't even show the weep hole in the diagrams.
    It's for neither.

    It's so you can capture the spring when you assemble the front pivot pin assembly.

    For installing the pin, detent and spring I just use the $5 tool and it takes maybe 20 seconds YMMV.

    I have a beer when I do it, because I saved $5 and used tools I already had!

    Not being argumentative, but I have not heard that in either of the two COLT armorer's courses that i have attended. Thye have taught the tool method, and it is a finese thing and once you get it it's easy. It is fun to see the detent fly across the room folowed by curse words.

    Well, that's what I was told in my Defensive Edge armorer's course.

    I guess you could use finese, or you could do it the easy way.

    But Colt people don't tend to like "good enough" but prefer "perfect".

    I assemble several lowers at work per month (can't drink beer there) and wrote the tool off on my taxes...............it's equipment for work YMMV.
