Analysis

The Smith & Wesson Model 310 Night Guard is the N-frame entry in the original Night Guard series. Chambered for 10mm Auto cartridge using moon clips, the handgun can also fire the .40 S&W cartridge, allowing shooters to run full-power 10mm loads for serious stopping power or milder .40 S&W for reduced recoil and easier practice. Grips were Pachmayr Compac Custom rubber for recoil absorption and secure purchase. The model appealed to enthusiasts wanting revolver simplicity with 10mm ballistics—deeper penetration and flatter trajectory than most .357 Magnum loads—without the weight penalty of a steel N-frame like the Model 610. The moon-clip system enabled fast reloads comparable to a semiauto mag change, though it required carrying clips loaded. In the handgun market, it filled a rare niche for big-bore rimless revolver carry, outperforming smaller-frame options in power but trading some concealability for that capability. Demand remains collector-driven today due to scarcity, with values holding steady or appreciating slightly for well-preserved examples.
