Before everybody got operator AF, we used to wear football receiver gloves. They're very thin, but it still took me a while to get used to the trigger with gloves on. Eventually I could shoot with or without and not notice a difference.
What kills me now isn't recoil, it's the DA trigger and decocking. My hands are a jacked up a bit from injuries and age, though.

Beware of my temper, and the dog that I've found...
All jokes aside, you may be shooting excessively. 500 rd days and 2500 rd classes invite repetitive type injuries to wrist and elbows specifically and perhaps to the shoulder. When I was much younger and shooting more, I had to use a wrist weight on my dominant hand to reduce felt recoil. There used to be some shock absorber wrist gismo's containing a liquid, and some used these. When still a teen, I developed a palm callous from extensive handgun shooting.
