IWB Kydex Holster for Sig P320 & Compact Pistols - Optic Cut Claw

In this review the IWB Kydex Holster is judged as a practical option for concealed carriers using Sig P320 family pistols and similar-sized handguns. The clearest reason to consider it is its balance of concealability and durability: the optic cut and adjustable claw let users carry an optic-capable setup while minimizing printing, and the.08 in US Kydex construction keeps the holster rigid yet lightweight for daily use.

Key Features

• Compatibility: Built to fit Sig P320 Full Size, P320 M17, P320 Compact, P320 M18 and P320 X Carry models, so owners of those pistols get a tailored fit without guessing.
• Optic Cut and Claw: The cut accommodates a wide variety of slide optics while the claw reduces printing for more effective concealment under a shirt.
• Compensator and Open Muzzle Cut: An over-cut muzzle area accepts many compensators and threaded barrels without rubbing the barrel tip.
• Full Length Sweat Guard and Posi-Click: The extended sweat guard keeps moisture off the slide and the audible click confirms the firearm is fully seated.
• US Kydex Construction: Fabricated from.08 in (2mm) Kydex that resists water and wear while remaining easy to clean for everyday carry.
• Adjustable Cant and Retention: Carry angle can be tuned from -5 to +20 degrees and retention is adjustable for a preferred draw and hold.

Who It's For

The holster is best for P320 owners and shooters carrying compact to full-size pistols who want an optic-capable inside-the-waistband solution that emphasizes concealability. It suits daily carriers who value a rigid Kydex shell with a full-length sweat guard and the tactile assurance of a posi-click seating.

It is less appropriate for users who plan to mount on-rail lights or lasers, since the model is explicitly incompatible with any light or laser attachments, or for those who need a very soft or highly padded carry system instead of a rigid Kydex shell.

Pros & Cons

• Posi-click seating gives clear audible confirmation the pistol is secure.

Cons

• Not compatible with weapon-mounted lights or lasers, limiting accessory options.
• Some users report mixed experiences with retention and comfort depending on body type and setup.
