A weapon loading system includes a handgun that has a slide and a magazine. A panel is provided and the panel may be worn. A holder is hingedly coupled to the panel and the magazine is removably coupled to the holder. The handgun is selectively positioned on the magazine to facilitate loading the magazine into the handgun with one hand. A block is coupled to the panel. The handgun selectively engages the block when the magazine is loaded into the handgun. The block engages the slide such that the slide is racked when the handgun engages the block. Thus, the handgun may be cocked with one hand.
