Today I was at the range again and after about 40 rounds the trigger felt worse. My shots were hitting poorly as well. So I packed up and at home checked the pull with my RCBS trigger pull gauge and sure enough the pull went up to 7.5 pounds.
I looked the frame section over and saw nothing out of sorts. The gun did fire but pull was awful.
I disassembled the frame and cleaned everything, reassembled and tested the pull and it was back to 5.25-5.5.
So, all I can think of was dirt got in the inner workings and made the pull heavy.
Went back to the range and fired 60 rounds, the gun is working perfectly and trigger pull tests at 5.25 pounds once again.
