When two designers separately make their trigger enhancement products, they may change the sear contact points, angles of surfaces, travel, fulcrum positions, etc. to achieve what they want.
If, when the gun is cocked, the supersear locates the sear/trigger nose contact point differently from the factory position, the TKO 1911 trigger probably won't work.
The sear contact point of the TKO trigger is closer to the trigger pivot point, therefore the 1911 trigger actually slightly increases the trigger blade travel before release... when used with a factory profile sear part. It also positions the finger slightly lower and further away from the trigger pivot point, thereby increasing leverage.
If the optional sear engagement set-screw mod is performed in conjunction with the 1911 trigger, I doubt you would be happy with it and a supersear in place.

I recall quite a kurfuffle about a similar question a few years ago.
Steve, I'd be glad to send you a 1911 trigger if you send me a supersear, and we can compare notes.
