Titanic fight stopping power for a handgun. The 10 miker miker ain't no joke princess. Some dudes can't handle it. For them, there's the tremendously less powerful and emasculating .40 Short and Weak.
How ever did you get to owning, what, 6 Glocks without a G19?!?
I've only owned 1 Glock, a Gen 4 G19. That said, I have a hard time imagining a Glock more versatile than the G19. (You did say "competition, training and carry." But I also understand that, having 6 Glocks, you may not need a jack of all trades gun . . . )

If the 10mm is uncomfortable in a Glock 20 the Glock 40 should tame the recoil a bit with being larger and heavier. The 40 is optics ready too which may be useful for competition
MOS Glocks may look cool and appear to be the new hot ticket, but dots have been around for decades in USPSA. The technique to quickly acquire a dot is far more difficult than acquiring iron sights, especially at contact distance. Dots do allow the focus to be on the target, rather than the front sight, which is use full to some shooters with vision issues. Both USPSA and IDPA recently approved a "Carry Optics" division, however magazine capacity is restricted to 10 rounds and scored minor. So you can download 40S&W to the minor floor. The .45acp MOS Glocks don't really have a home in either USPSA or IDPA because the scoring is minor. Long slide 10mm’s would work for hunting with a small dot, but that’s already been done with 6” barrels.
Looks like a G19 could work for you.
