Peco has announced a set of rather sharp HOn30/OO9 turnouts, although not as sharp as the Egger-Bahn switches. The turnouts (product codes Peco ST-U404 and 405 for left hand and right hand) are based on the brand´s N scale set track #1 radius (that´s 9"), but not yet available in the market. They have been announced for almost a year now, so it shouldn´t be too long for them to show up.
Assuming that you have need for only one or two such turnouts, have you considered rolling your own?
I have hand-laid 9mm gauge code 55 turnouts, and doubt that the very tight radius would give me a problem. If I can bend appropriate flex track to the route and my stock will run on it, I can build it. (When I build my mine trams I will be hand-laying 6mm and 7.5mm gauge with Code 25 and Code 40 rail, including swinging-point turnouts and some truly horrendous curve radii.)
Actually, I thought you were addressing a different situation, which I have, and have learned to deal with. The points that snug up to my un-notched stock rails are razor sharp - you do NOT run fingers along the rails into facing points!
