I can't shoot 10mm cuz of my arthritis. But I did see a vid showing how the Glock flexes and compared to all-metal 10mm pistol may have less perceived recoil?
I don't perceive the recoil of 10mm in a Glock 20 as bad at all. In fact, I found it pleasant to shoot. Of course I haven't tried any super hot loads, but for regular off the shelf stuff, it's very manageable. That said, I don't have arthritis, so I can't speak to how that would feel.
