What kind of mags were you running when you had problems with WWB ammo --- that is a factor too.
Not trying to confound the issue however that is an element as well --- Also are you sure that the issue was slide speed and not that it failed to fully cycle? Not to mention that WWB is often rather anemic so if I had a problem with a gun and WWB my first step would be try some stiffer practice ammo or actual duty ammo.
I give you a ton of credit for your curriculum at school of hard knocks gun smith school. Been there, still am there.
In the 1911 EVERYTHING is variable... I tend to be a wilson parts guy for the most parts their parts are way closer to where they need to be, most of the time... either work out of the box or are darn close. Ed tends to be a slightly bit more.
If you really want to chase down this weird sensation you are feeling with hammer manipulation degrease every part and put dykem or blue sharpie all over the parts, re-assemble dry, manipulate 100 times and you should be able to see where the rub or issue is. I saw a similar once where a coil of of main spring was touching the extension of the spring cup that goes down the center of the spring --- this could be the spring being slightly off or whatever --- your critical aspect of the spring cup is that it slide up and down in the MSH freely and does not bind anywhere some polishing of the all the parts and the MSH bore can work wonders, mine also has graphite in it on assembly.
