Description
While not their first endeavor into polymer frame striker-fired pistols, Smith & Wesson’s M&P features many design improvements over their lower cost Sigma series pistols. These features include an improved trigger action, field interchangeable palm swells, black Melonite finished stainless steel barrel and slide with twin scalloped slide serrations, a Zytel polymer frame reinforced with a stainless steel chassis, and an accessory rail.
The 357 SIG cartridge was developed by SIGARMS in partnership with Federal Cartridge.The cartridge uses a bottlenecked .40 S&W casing crimped to a 9mm bullet.
