I love the feeling when my XM is just right. I only have one and I carry it every day, so naturally it gets daily use. Tonight, I gave mine a full clean up and touch up- including stuff I rarely do like oiling the CF scale. There is that moment when the scale is right, the action is dialed in, the lock is perfect, the centering is perfect, and the edge could split atoms that is so perfect. I love using mine, but being able to take it back to perfect can be so satisfying.
