Thanks Rory.
Not sure if that is The "cement mixer" test, but sounds like it. Grueling.
In any case, this article seemed to think the Savage pistol out performed Luger and Colt in the sand test.
" One test involved blasting each pistol with fine sand for one minute. After this treatment, the tester blew and brushed the sand off the pistol and fired it to assess its reliability. In another torture test, each handgun was degreased, its barrel plugged, and the weapon immersed in a corrosive solution for five minutes. Another reliability test followed. The Savage bested both the Luger and the Colt in the sand test and delivered projectiles at a higher velocity than either."Pistol Trials article
