Partly due to this thread, and partly due to @Lost River’s frequent-ish mentions of the stellar performance and accuracy of his G21, I borrowed a bud’s nearly new G21.3 SF. Put half a box or so of rounds through it today.
Meh. It’s nice enough, I’d take one if someone was handing them out, but I’m probably not going to spend any money on one in the near future. If I see a G21.5, I may give it a spin to see if I like it better, but today I went back and forth between my G19X with large backstrap and beaver tail and the G21.3 SF, and I no longer feel any attraction to the .45 in this format. Much prefer the 9mm in the full-size Glock, and 1911 or 3rd gen S&W in the .45.
