The 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.

SIG Sauer P320 Features

The SIG Sauer P320 is a semi-automatic striker-fired 9mm pistol with unparalleled modularity.  Available with optional features such as an optics-ready slide and ambidextrous thumb safety, this gun can be configured in countless ways.  Its frame, or “grip module” can easily be replaced by the user to change grip size, height, and color allowing the user to take this gun from a full-size to a compact or sub-compact setup.  The trigger housing, which contains the trigger, sear, and slide rails among other parts, is the controlled part of the gun and everything else is replaceable, allowing the user to tailor this gun to their liking.

SIG Sauer P320 Capacity

The SIG Sauer P320 uses a fully-modular design allowing its grip module to be replaced between full-size, compact, and sub-compact layouts.  Sub-Compact magazine capacities are 10 or 12 rounds, compact magazines carry 15 rounds or are limited to 10 rounds, and full-size flush-fit magazines hold 17 rounds.  Extended magazine capacities include 21 and 32 rounds.  Larger magazines can be used on all smaller frames; be sure to use magazine spacers to avoid damage to internal components

SIG Sauer P320 Ergonomics

Ergonomics
The SIG Sauer P320 uses low-cost grip modules to give the user plenty of different options to tailor their P320 to their needs.  Users can choose from different grip widths as well as different grip heights.  The magazine release is reversible to accommodate left and right handed users, the safety is firm yet easy to manipulate, and the trigger has an incredibly smooth 6 pound pull.

SIG Sauer P320 Fit & Finish

No matter the configuration, the SIG Sauer P320 is made with well-engineered and properly manufactured parts.  Its trigger is incredibly smooth when compared to other factory triggers, and its highly-contoured replaceable grip modules give the user a gun that perfectly fits in the hand.  The coatings on the metal components are all very durable and disassembly couldn’t be easier.

SIG Sauer P320 Concealability

Thanks to its modular design, the P320 line can be configured without tools into a sub-compact setup.  This allows the user to change the format of the gun to fit whatever role needs to be filled.  Both the compact and sub-compact setups are easily concealed with the right holster and attire.
