This has only happened to me on one gun and the damage was permanent and still aches at times.

It was when shooting heavy 400 grain DG hand loads in my Winchester 1895 .405 WCF. Upon examination, it was apparent that the space forward of the trigger was tight AND the recoil of 400 grain loads was significantly more than the factory 300 grain loads. Knowing this, I was able to avoid further problems by remembering to adjust my grip for DG loads.
Also, I always wore shooting gloves with that rifle and do so with shotguns too.
