Will a drop-in cartridge style trigger assembly cooperate with an 80% lower? Obviously the trigger well will have some varying dimensions so there's a possibility of the trigger housing being too wide or too narrow to fit properly. Do cartridge triggers have some way to manage this?

The trigger pin and hammer pin width is standard, even on a drop in trigger group, so provided you milled the lower to spec, it should theoretically install the same as a traditional trigger group. However, there's always a chance of rough spots not milled enough in width or depth which could make the entire enclosed housing not slide in correctly to line up pins, but if that's the case, just put it back in the jig to see if you went too light on a side.

Since you don't have the spring tension holding the assembly in place I recommend some screw in anti walk pins. like these.

Timney and others use screws in their trigger housing that you tighten down against the floor of the receiver, holding the housing securely in place. With this, the hammer and trigger pins can not rotate or walk.

some of them if you over tighten, it effects the hammer and trigger adding more friction etc. really depends on the design.
most of them are designed to take up some of the slop and you still use anti walk pins.

to the op a 80% should be no different then a standard lower when you done with it. your doing the rest of the work a company would do on a forging normaly.
