I have found that if I am not on the range regularly with my compact 3rd gens ( 3904,6904, shorty 40, TSW 4013 ect ) I have a tendency to put to much finger in the guard and will pull low left consistently with them. Takes a little time to get the groove back and then I will shoot well with them. I normally carry a 5943 DAO and shoot it often but will struggle at first when I go directly to the normal D/SA smith and pull low and left. It's a fight for a few rounds until I think about it and watch how I hit the trigger with my finger.
