Sig Sauer P320 Full Size 9mm Luger Semi Auto 10 Rounds 4.7” Barrel Night Sights Black review offers the following information; Sig P320 is a polymer-framed service pistol designed from the ground up with the input of law enforcement officers. The result is the most operator-safety focused striker duty pistol on the market today. Taking into account the concerns of military and police training officers, the P320 provides an enhanced level of safety not found on most modern service pistols. Unlike its competitors, the P320 does not require the operator to pull the trigger nor use a special tool to take-down the firearm for cleaning or routine maintenance. Featuring a modular grip frame and removable fire control assembly pioneered by Sig Sauer, the P320 is customizable to any hand size or duty requirement. The P320 can quickly be converted from a Full-size to a Carry pistol. Slide and barrel conversions allow the P320 to change between calibers and barrel lengths as well. The P320 will be immediately available in 9mm, .40S&W and .357SIG, with .45ACP coming later in 2014. With a partially pretensioned striker, the P320 has a short, crisp trigger pull with a quick, pronounced reset right out-of-the-box. Featuring the Sig internal safety system, the P320 has no external safety or decocking lever to snag or hang up on the draw. SigLite night sights come standard, and the reversible magazine release makes the P320 completely ambidextrous.
