Who'd buy a P90 if Ruger chambered it for the 38 Super Auto?

I'm surprised that more don't offer pistols chambered for the 10MM. I think a Steel Framed Pistol like the Ruger P90 could be designed for the 10MM and made work. Glock has made it work for them. Here's an interesting thread about the 10MM and might be the reason most Mfg's stay with the Basic Calibers.

Actually the P90 is an alloy (aluminum derivative) just noting it.
