Amomax Tactical Holster for Sig Sauer P320 Full-Size M17, Black

If you're running a P320 Full-Size or M17 and need a no-nonsense holster that doesn't fight you, this is the baseline option. Amomax's design holds the pistol securely and releases cleanly on draw, without the bulk or price tag of duty-grade gear. It's for the player who wants their sidearm ready without the learning curve of a high-retention system.

What fits. This holster is built for the P320 Full-Size frame, which is the same size as the M17 military variant. Compact or Carry models won't seat properly, and neither will the P320X. If your slide is shorter or your grip module is different, you need a different SKU. Check your frame size before ordering.

Retention and draw. The interior contours to the pistol's shape, so it stays put when you move but doesn't require a tool or release lever to draw. You'll want to break it in with a few dozen dry draws before relying on it under pressure—new holsters can be stiff, and a smooth draw is a trained motion, not a default.

What you need to know. This is just the holster. The pistol is not included. No belt, no mounting hardware beyond what's integrated into the design. If you're mounting to a plate carrier or tactical belt, verify the attachment method matches your setup.

Before you buy. Holster fit is model-specific. A P320 Compact will not work in a Full-Size holster, and vice versa. If you're unsure which frame you have, measure your slide length or check the model number on the grip module. When in doubt, ask before you order—returns on holsters are more hassle than getting it right the first time.
