Once you get it open after firing, check the primer. If there is drag marks on it then you can do one of two things... try an different ammunition/primer and see if the problem solves itself OR you re-dress the tip of the hammer as Edgar suggested. I have had this issue happen with a flattened hammer tip personally. But primers can be soft and cause issues as well.
If there is not drag marks on the primers, then you have another issue.
