Straight answers on Incog X P320 Large Light mag caddy retention, light-bearing holster fit, and cant adjustment for Sig P320 owners.

Quick answer

The Incog X P320 Large Light with Mag Caddy is a deep-concealment IWB hybrid holster built for a Sig P320 with a large weapon light, and most questions come down to three things: confirming your exact P320 model, setting retention for the light-bearing shell, and choosing a cant that keeps the mag caddy usable.

Why light-bearing fit questions come up first

A light-bearing holster indexes on the light and the slide, so the shell is shaped around a specific combination. The Incog X P320 Large Light fit is listed for the Sig P320 with a large weapon light, but the catalog does not break out every slide length, optic cut, or light model. If your setup differs from the listed fit, treat that as an open question rather than assuming it will work. Check the product page for the current fit note before you order, and test fit with an unloaded pistol.

Retention and the mag caddy are separate adjustments

The holster's handgun retention and the mag caddy's grip on the spare magazine are independent. Tightening one does not fix the other. Adjust the handgun shell until the pistol seats with a positive click and stays put during a shake test, then tune the mag caddy so the magazine does not rattle or drop free when you move. Do this with the holster off the belt first, then repeat on-body.

Cant is a comfort and access trade-off

The Incog X is described as multi-positional, so you can set cant to suit your carry position. More forward cant usually helps concealment and draw access behind the hip, but it also rotates the mag caddy, which can change where the spare magazine sits against your body. Find a cant that keeps both the pistol grip and the magazine accessible without printing, then lock it down and practice draws from that position.

Incog X P320 Large Light Mag Caddy: reader questions

Will this holster fit my P320 with a large light?: The listed fit is the Sig P320 with a large weapon light. The catalog does not list every light model or slide length, so compare your exact setup to the fit note on the product page before ordering. If your light is not a large model, this shell is not the right starting point. Test fit with an unloaded pistol before you adjust anything.
How do I set Incog X mag caddy retention?: Adjust the mag caddy separately from the handgun shell. With the holster off-body, insert the spare magazine and tighten the caddy until the magazine stays put during a gentle shake but still releases when you pull it firmly. Recheck on-body, because belt pressure can change how the caddy grips. Retention that feels right off-body may need a small tweak once the holster is on your belt.
Can I change the cant on the Incog X?: Yes, the Incog X is multi-positional, so you can adjust cant. Loosen the attachment, set the angle, and retighten. Change one side at a time and check that the mag caddy still sits where you can reach it. After any cant change, practice a few draws to confirm the new angle works for you.
Where should I carry the mag caddy?: The caddy is attached to the holster, so its position follows the holster's cant and ride height. Try appendix and strong-side behind the hip, and pick the spot where the spare magazine does not press into your hip or print through clothing. There is no universal answer; your body and wardrobe decide. Wear the setup around the house for an hour before committing to a carry position.
