I just picked up the latest (July-August 2024) issue of American Handgunner, which has two articles by Mike. One on his favorite handguns, and the other on British .380 Revolvers. I'll keep that issue along ide his great books. Don't know if those will be the last article to be published. Depends on whether AH has a backlog of articles. As always, his wife, Yvonne, did the outstanding photography accompanying the article.
When Ruger brought out the Vaqueros in .44-40, they made a mess of chambering the first ones. I bought one of the first, and Ruger refused to take it back, until Mike complained about this in print, and I complained about once a week, until they finally gave in and replaced the cylinder (although they left the throats .425"). I am sure that if Mike hadn't written them up, I'd still be waiting to have uniform chambers. (I left the throats at .425", however, and using .430" hardcast bullets, mine drive like tacks!)
RIP, Duke, we won't see your like again! :'(
