Probably not .357 Sig...from his book, "The .357 Magnum is presently the best cartridge available. With the 160 grain bullet in 4-inch barrels it delivers slightly more than 1200 (feet per second) ...and an authoritative 500 plus foot pounds of energy. While a little more shock power would be desirable, no other available cartridge is so near the ideal for police use."
The ideal, he wrote, would be a ".41 caliber loaded to between 1200 and 1300 (feet per second) with a 200 grain semi-wadcutter bullet."
Of course, he was advocating for the .41 Mag, but it is very interesting to people like me with too much time on their hands sometimes to wonder if the 10mm would have been his huckleberry. After reading No Second Place Winner and as having started my LE career with issued L frames, I've been shooting old revolver qual courses with my 5" GP-100 10mm and can't help thinking it would have been pretty ideal back in the day.
