Thanks, man! I appreciate it. I’ll plug @FrankB for his channel, too—here is the lovely 5926 in question:

He’s got some cool revolvers, too.
But yeah, my 6904 and 5906 have totally reliable, eat-anything kinda guns. Same with my 645 and the 3913 I had briefly. I did have some FTFeed issues with my 1076 and some of the more compact 45XXs. So, I’m thinking I’ll stick with 5 inch for the big bore Smiths. But 59XXs, I think, have a reputation for being dependable and durable.
