The Beretta M9A4 represents the pinnacle of the Beretta M9 series of pistols. Built to exceed the standards of even the most demanding tactical shooters, the M9A4 blends the proven design of the M9 with modern features such as a red-dot optic compatible slide and dovetailed tritium night sights for optimal sight options, an enhanced short reset Xtreme Trigger System, an 18-round magazine, and a Beretta Vertec frame with included aggressively textured Vertec-style thin grips that ensure a more natural fit for all shooters. The red-dot ready M9A4 features integral slide cuts to allow for the mounting of optional optic plate styles. Shipping with blanking covers, the end-user is able to purchase one of five different plates that allow for mounting of all of the most popular optic variants on the market today.
