Interesting. Agree, they should offer it without a rail as well. The example pictured on the link, unlike in the first post of this thread, shows no grip screws, the grips dovetailing on and held by back strap and mainspring tension. Cool, but will limit grip selection for those so inclined.
I have a friend who may spring for one. I'd be far more tempted if railess.
The rail is only of interest, for me, on a nightstand gun, and that gun must accept a suppressor. Doable, maybe later on this one, but the muzzle looks so nice without . . .
Edit . . . well, duh, I guess it does come without a rail as evidenced by the picture above this post!
