I own a "newer" version of the Sig 250 in 9mm. Bought the "kit" for 40 S&W which came with a slide, magazine, and takedown lever. I cannot get different grip modules from Sig. The only "kit" I have found and bought came without a grip, and was meant for COMPACT not full size. Must be soon, how else can one explain the Sig Sum 2 packages they have been dropping all over the gun shops.
