The Sig Sauer P320 Grip Module X-Series Compact in large size is the foundation piece for building or reconfiguring a P320 platform pistol. If you already own a P320 or P250 fire control unit (the serialized, regulated part), this grip module lets you swap it into a compact-size frame chambered in 9mm Luger, .40 S&W, or .357 SIG. It's made for shooters who want modularity without buying a whole new gun—take your existing FCU and adapt it to a different size or caliber configuration by pairing this grip with the appropriate compact or sub-compact slide and barrel assembly.
Constructed from durable black polymer, the X-Series Compact large module is engineered around Sig's modular P320 platform, which has proven itself in military and law enforcement use as well as in civilian shooting sports. The large grip size accommodates shooters who prefer a fuller grip profile on a compact-length slide. This is the key to the P320's flexibility: the grip module, slide, and FCU are fully interchangeable within compatibility parameters, so you can tailor your setup to your hand size and intended role without reinvesting in the whole gun.
Keep in mind that this grip module is designed specifically for compact and sub-compact P320 slides (3.60\" and 3.90\" barrel lengths). It will not work with full-size P320 slides, as it won't properly cover the full-size dust cover, leaving the recoil spring and guide rod exposed. Also note that X-Series grip modules are compatible only with magazines featuring the SIG Mark baseplate; magazines marked with "SIG SAUER" on the baseplate are not compatible with this module.
