This OWB rig is specifically hand-molded to accommodate your gun with light, ensuring a rattle-free fit and perfect retention.

How to Choose the Best Holster for SIG P320
Selecting the perfect holster for SIG P320 requires understanding the modular nature of this firearm. Because the P320 can be converted from a Full Size duty gun to a Compact or Sub-Compact frame, you first need to identify your primary carry goal. For those using the P320 as a daily concealed carry weapon, a IWB holster is the gold standard, offering a slim profile that hides the striker-fired frame effectively. If you prefer comfort and don’t mind a cover garment, a OWB holster in a pancake style will distribute the weight of a loaded 17-round magazine much better.
Material and features are the next critical factors. A SIG P320 leather holster provides a silent draw and unmatched comfort for all-day wear, as the natural material breathes against your skin. If you’ve upgraded your pistol with modern accessories, ensure your choice is a holster for SIG P320 with red dot or a specialized light-bearing model. Given the P320’s smooth trigger, your holster must be hand-molded to provide a "click" fit that fully protects the trigger guard.
Finally, consider your environment. If you spend significant time driving or in a seated position, a SIG P320 shoulder holster or a chest rig might be more accessible than a traditional waistband position. Always prioritize a holster that offers a balance of secure retention and a smooth draw path, ensuring that your gun is ready the moment you need it.
Best Holster for SIG P320 FAQ
Generally, no. While the P320 is modular, a holster molded for a SIG P320 Compact will usually be too short for a Full Size slide. However, an "open muzzle" holster can often accommodate different slide lengths. For the best safety and retention, it is always recommended to get specifically molded for your exact frame and slide configuration.
Yes, provided the holster is high-quality and hand-molded. Because the P320 is a striker-fired pistol without a manual safety (on most models), your SIG P320 holster must feature a reinforced mouth and a perfect fit that completely covers the trigger guard. Premium leather holsters from Craft Holsters are molded to the exact geometry of the gun to ensure it cannot be discharged while holstered.
The best option is an "optics-ready" or "optics-cut" holster. Since many P320s come from the factory ready for a Romeo1Pro or Holosun, we design our SIG P320 IWB holsters and OWB rigs with a lower cut at the slide's rear. This allows the optic to sit outside the leather, ensuring it doesn't interfere with the draw or the retention.
No. A light-bearing setup changes the entire profile of the firearm. If you have a SIG P320 with light (like a TLR-1 or X300), you must use a dedicated light-bearing holster. These are custom-molded to the shape of the light itself, which is where the primary retention often occurs in these setups.
To minimize printing with a SIG P320 holster, especially the Carry or Full Size models with longer grips, try an IWB holster with a slight forward cant. Positioning the holster at the 4 o'clock mark allows the grip to follow the natural curve of your back. Additionally, a high-quality gun belt is essential to keep the P320's weight from pulling the holster away from your body.
CONCLUSION
The SIG P320 is one of the most capable and versatile handguns on the market today. Whether it’s serving as your duty weapon, your home defense go-to, or your daily concealed carry companion, it deserves a rig that matches its quality. From the rugged Alaskan shoulder holster for the trail to a discreet P320 IWB holster for the city, choosing a custom-molded leather holster ensures your P320 is always secure and ready for action.
