The new Spec Series pistol comes complete with co-witness sights and a 4.6 threaded barrel, making it an optimal choice for suppressed shooting. Also included is the Smith & Wesson C.O.R.E. system, designed to give the user the ability to mount their preferred handgun optic to maintain accuracy and proficiency when firing. The inclusion of two 23-round 9mm magazines means less time reloading and more time practicing. The additional 15-round magazine trims down the overall size of the new Spec Series and allows for a more concealable package.
