Features 

At 11.5 oz and 6.25 inches overall, the 351 C fits in a holster or jacket pocket without demanding attention. The DAO action keeps the trigger pull consistent shot to shot and eliminates the need to manually cock the hammer. The XS Sights White Dot front sight gives a clean reference point across varied lighting, which matters at close defensive distances. 
 
.22 Magnum delivers more energy than standard .22 LR from a short barrel, making it a more credible carry caliber than its rimfire reputation sometimes suggests. Seven rounds in the cylinder is reasonable for the gun's size. 
 
New shooters get manageable recoil with meaningful ballistics. Experienced owners who want a compact backup or training revolver get a well-made, low-maintenance option.

The S&W 351C draws fairly predictable reactions from owners. The weight and dimensions are the most-cited selling points - at 11.5 oz, most owners report comfortable all-day carry, and the compact frame handles easily.

The .22 Magnum caliber generates real debate. Many owners consider it adequate for personal defense given its manageable recoil, especially for new shooters or people who find larger calibers uncomfortable. Others argue that .22 WMR falls short compared to centerfire defensive calibers and recommend the 351C primarily as a backup gun or training tool. Both positions come up regularly and neither side is wrong - it depends on what role the gun is filling.

The DAO mechanism gets mostly positive feedback for its simplicity and consistent pull, though some owners note the trigger weight takes adjustment. Reliability gets frequent mentions; owners generally report trouble-free function with minimal maintenance.

The 351C is typically framed as a dependable backup or starter revolver, and most people who buy it for those purposes come away satisfied. Buyers expecting primary-defense performance from a .22 tend to have more mixed views.
