Last night before I left to help the Bellevue PD with our VIPS group I unloaded and checked my cc pistol. When I got to the police station I disarmed and put my pistol in the trunk. After our detail was finished I went back to the police station to get my car and drive home. When I retrieved my pistol from the trunk I noticed I hadn't replaced my loaded mag into my G19 before I left my house. I did have a round chambered though. In 20 years this has never happened to me. Just a reminder to check, double check and check again!
