Most defensive encounters occur at night, so how do you know what equipment to use? And even then, does it make you more effective? Field Editor Adam Heggenstaller heads to Oregon for the Crimson Trace Midnight 3-Gun Invitational, where competitors use lights and lasers on rifles, pistols and shotguns in a challenging match fired completely in the dark. Speaking of 3-gun, Joe Kurtenbach evaluates the Stag Arms 3G rifle, built to be ready for competition right out of the box. For "I Have This Old Gun," we bring you the recoil-operated Remington Model 11-48, one of the first new shotguns of the post-World War II era.
