I have Swift 27x1 3/8" tan walls--lovely looking tires. Ride is nice--haven't ridden them enough to see how they handle at the limit, but no squirreliness thus far. They do run small, certainly on 27x1 rims (Champions). Price is great, too. I know Continental used to make a Grand Sport in 27" of some sort. Their very recent website redesign is complete and utter garbage for navigating and seeking information, so I don't know what's available there.
