Smith and Wesson L frame chambered for 10mm Magnum (lengthened 10mm case) using a titanium cylinder (for sufficient strength) with a triple lock style lock up, 5 inch gain twist rifling SS barrel with partial underlug. Forged hammer, and trigger. No MIM parts need apply. Stainless steel frame. Finish the entire piece in Robar NP3. Fully tuned/polished action
That would be a good all around revolver. Weather proof, powerful, able to fire a wide range of ammo (.40S&W, 10mm, and 10mm Magnum), and not quite as big as an N frame. I don't know that the gain twist rifling would add anything but S&W uses it on the .460 and it seems to perform pretty well there.
