I am looking for advice/ Input as to the EDC between the Fenix P1D CE and the P2D RB100? I noticed the size is 2.8 inches long on the P1D CE and 3.1 on the P2D RB100. Would the difference in .3 inches be that much? I currently carry a Peirce M10 but want to upgrade a little. Thanks in advance for all suggestions and advice.
