The Smith & Wesson Airlight 351PD is a small frame personal defense revolver with decades of reliable performance to its credit. The 1 7/8" barrel is actually two separate parts. There is a stainless steel "barrelette" within an aluminum shroud. The original design was conceived to prevent the barrel from unscrewing itself with hot magnum loads. The Smith and Wesson Airlight 351PD uses a HIVIZ® Fiber Optic Orange front site with U-Notch rear making it easy to find, site, aim and return to target after firing. Wood grips make getting a good purchase on the weapon easy. The small J-frame 351 Airlite has a low profile non reflective black matte finish for excellent concealed carry, holds 7 rounds of 22 Magnum, and weighs just 11oz.
