It is very possible simply adjusting my grip will help. Looking at the location of the swelling (it is still sore BTW) I was thinking that the metal hump that conceals the hammer might be coming back and hitting my hand. However, it may be possible it is the cylinder latch.
The location of the welt is starting on the top of my thumb at the base right at the first knuckle and then then moving forward at a slight angle to about halfway into the web of my thumb. At its worst it was about the size of a quarter. What is still there is about the size of a nickle.
