The other day while cleaning my P3AT, I noticed that when I slowly pull the trigger back about 1/16", there is a felt click or thud as the hammer rolls of the hammer block. I felt again it when I slowly set the trigger back. I didn't let the hammer fall while disassembled. Dry firing, I can feel the click also. I can't remember every feeling it before. It is not as noticeable when normally pulling the trigger during dry firing, but now that I know it is there, I can detect it. Is this normal or am I going to have issues with the hammer block?
