Sig P320 Holsters Built for a Precise Fit

Every Zero 28 Customs holster for the Sig P320 is molded directly from a real firearm, not a generic mold shared across multiple pistols. That means a snug, consistent fit with correct retention right out of the box, whether you're carrying the standard P320 Compact, Carry, or full-size models.

IWB vs OWB

Our P320 lineup includes both inside-the-waistband (IWB) holsters for deep concealment and outside-the-waistband (OWB) holsters for range and duty use, so you can choose the carry style that fits your daily needs.

Materials, Retention & Craftsmanship

Each holster is hand-formed from 0.080" Kydex and hand-finished with smoothed edges for comfortable all-day wear. Retention is fully adjustable via a single tension screw, so you can dial it in to your preference.

Production Time

Because every holster is molded and finished to order, please allow our standard production time before your order ships. Exact estimates are shown at checkout.
