I agree fully on one, kinda on another, and the third is kinda bovine excrement.
I agree completely about FLGR’s in 1911’s...completely unnecessary in a Gov't (5”) or Commander (4.25”), and more trouble than they are worth—an elegant solution to a non existent problem.
I kinda agree with the 3-dots—unless we're talking tritium. Then, muted rear dots with a brighter front are desirable.
And the excrement? Well, when he ragged on some gun store guy calling it a ”slide release” and then gets it just as wrong as well—”slide stop”—he pretty much lost any credibility he might have had. It's a “slide stop release”...because you can RELEASE the SLIDE STOP by pressing it down; that’s what it's there for. And while some makes of pistols have minuscule ones (Glock, for instance), not all pistols do, and using the SSR is perfectly acceptable on those models.
