Best Leather Holster for Sig P320 (Overall)

If you want one do-it-all OWB, the Concealable 2.0 is our top pick. Its contoured, hand-molded steerhide rides close to the body for better concealment, the low-cut front works with many carry-style red dots, and the raised sweat guard improves comfort against the slide. A mild butt-forward cant and the 1.5" belt slots keep your setup locked in—exactly what most people want in the best holster for the Sig P320.

Best Tuckable Option (IWB)

Need to tuck a dress shirt over your Leather Holster for P320? The Tuck-N-Go 2.0 brings minimalist comfort with adjustable cant, a reinforced mouth for easier re-holstering, and clip options that let you run strong-side, appendix, or crossdraw while keeping your Sig P320 holster discreet under a tucked shirt.

Best Budget IWB

For simple, everyday concealment at a friendly price, the Stow-N-Go covers the essentials: comfortable leather body, open-top speed, and a stable ride height. It’s a straightforward P320 holster that just works when you want reliable daily carry without frills.

Best Shoulder Holster

Wear a jacket all day or spend lots of time seated? The Miami Classic remains the iconic shoulder holster for P320 carriers. Its spider-style harness distributes weight evenly, the horizontal orientation speeds access, and the included off-side mag carrier balances your load for long, comfortable carry.

Ammo Carriers for the P320

Keep spare magazines as dependable as your holster. The DMC – Double Magazine Carrier uses dual tension screws and secure snap loops for confident retention on common belt widths, while the SMC – Single Magazine Case offers a compact, ambidextrous option when you want to travel lighter without sacrificing accessibility.
