The SIG Sauer P320 is known for modularity, but some of the most noticeable improvements do not require rebuilding the entire pistol. The controls that connect your hands to the platform can have a major influence on how comfortable, predictable, and consistent the P320 feels.

The SIG Sauer P365 earned its reputation by fitting impressive capability into a remarkably compact package. That small footprint is one of its greatest strengths for concealed carry, but shooters with bigger hands can sometimes find the standard configuration more difficult to grip and manipulate comfortably.

The Tyrant Weapon System 365 and Flux Raider 365 approach the same basic concept from different directions: take the modular SIG Sauer P365 platform and place it into a compact PDW-style chassis that provides additional stability, accessory capability, and onboard magazine storage.

The SIG Sauer P320 is one of the most modular striker-fired pistols on the market, making it a popular platform for customization.

The SIG Sauer P365 XMacro and P365 Fuse take the modular P365 platform in a similar direction: more capacity, a full firing grip, and better shootability while maintaining the narrow profile that made the original P365 successful

The TWS365 offers SIG P365 owners a unique way to enhance stability, control, and overall shooting performance while maintaining the compact characteristics that make the P365 platform so popular.
