I've seen a lot of folks on the Smith & Wesson Forums saying that the 10mm 3rd Gen pistols like the 1006 and 1076 can shoot .40 S&W without issue.
Based on what I've heard, I would surmise that practically any 10mm pistol can safely fire .40 S&W because literally every 10mm pistol I've heard of will headspace .40 S&W on the extractor and provide adequate case support to prevent blowouts.
That being said, a lot of commercially available, factory loaded 10mm ammo are the old FBI Loads, which are literally just .40 S&W in a longer case, with any minor difference in performance printed on the box being a result of the use of a longer test barrel. (Seems like most 10mm ammo is chronographed from a 5" test barrel while .40 S&W is more often chronographed from a 4" test barrel.) Furthermore, I've seen a humiliating amount of folks who like to brag about the incredible power of their 10mm handcannon on forums, then post pics of their firearm amidst boxes of 10mm FBI spec ammo, evidently completely unaware that their mighty 10mm is being fed ammo no more powerful than .40 S&W, so there's a possibility that a lot of the folks who are shooting .40 S&W out of their 10mm pistol are using pistols which have already been setup to function with FBI spec 10mm loads, hence why they function perfectly with .40 S&W.
Personally, I would like to hear from some folks who shoot full power 10mm loads and have tried .40 S&W out of the same pistol, as I wonder how well .40 S&W would function in a 10mm pistol with the proper recoil springs installed to handle full power 10mm Auto.
