Our Selected Top 13 Sig P320 Rx Holster You Can Trust
This list features carefully chosen holsters designed for a specific handgun model, detailing their fit, durability, and ease of use. Each review highlights performance, suitable users, and key advantages and disadvantages to help readers make informed decisions.
1. Safariland 7378RDS 7TS ALS Holster
People who carry a SIG P320 RX and want a holster that balances quick access with secure locking will find this one fits the bill. Its standout feature is the Automatic Locking System (ALS) which locks the weapon automatically when holstered yet lets you draw up easily once it’s released.
Setting up the holster is straightforward, and day-to-day use feels reliable thanks to the open-top design that speeds up weapon retrieval. The SafariSeven nylon blend ensures the gun’s finish stays scratch-free, while the raised interior stand-offs help keep dirt and moisture off the firearm, which is convenient for those who carry frequently or in varied weather conditions.
The holster does a solid job holding the SIG P320 RX securely while allowing smooth draws when needed. Its material handles extreme temperatures well, so you’re not worried about structural failure in heat or cold.
Users praise its dependable locking action but some mention that without an SLS (Self Locking System) there’s no added retention beyond the ALS, so it may feel less secure for very active use.
Positive feedback highlights the reliable ALS that locks the firearm firmly yet allows a smooth draw. The most common drawback is the absence of a secondary safety lock besides the ALS, which may be a concern in high-movement environments. The material and design also help keep the firearm clean and protected during everyday carry.
This holster suits those who value quick access combined with secure locking, especially in a wide range of temperatures. It might not be the best choice for users needing maximum retention for vigorous activity or lightweight setups.
Pros
- Automatic Locking System for secure holstering
- Non-abrasive nylon protects firearm finish

How to Choose the Right Sig P320 RX Holster
Comfort, retention, and material quality are key factors when selecting a Sig P320 RX holster, as they ensure secure carry and ease of access. Choosing the right fit prevents wear on the firearm and avoids unnecessary expenses from replacements or adjustments.
Fit and Compatibility
Trying to fit a handgun with an optic into a holster designed only for the bare firearm results in looseness or difficulty drawing. A well-made holster has precise molding shaped exactly to the specific handgun model including the mounted optic. This snug fit prevents the firearm from shifting during movement, which is crucial for both comfort and safety.
Holsters tailored for a particular frame size and grip type further improve security and retention, as even small variations in grip texture or width can affect how the gun sits inside.
Common issues arise if the holster is too generic. The firearm might rattle, causing noise and wear or it may be difficult to reholster.
Proper sizing means checking manufacturer specifications for exact model and accessory compatibility. Good holsters often specify which frame variants or grip extensions they support, ensuring the gun stays firmly in place without extra adjustments.
Retention and Security
Retention is a major factor affecting how fast and reliably you can access your firearm. Holsters with adjustable retention let you dial in the tension so the gun won’t fall out during vigorous activity but still draws smoothly. Mechanical retention features, like thumb breaks or active locking systems, add an extra layer of security against accidental removal, especially when carrying in crowded or dynamic environments.
Without proper retention, the gun may slip partially out or shift, risking malfunction when you need it most. A good retention mechanism feels consistent: firm enough to hold the gun securely but not so stiff that drawing becomes slow or awkward.
Look for models allowing customization of tension or retention level, since user preferences and daily activities vary widely.
Material and Durability
Holsters see daily wear against skin, clothing, and environmental exposure. Materials like durable Kydex or injection-molded polymer hold up well against sweat, dust, and moisture without deforming or breaking down.
Some cheaper plastics can crack or warp over time, which compromises both fit and safety.
Balance between rigidity and flexibility affects comfort and function. Too rigid, and the holster can dig into your body or clothing; too flexible, and it may lose structural integrity, leading to inconsistent retention.
Strong, abrasion-resistant materials ensure the holster maintains its shape and secure hold over months or years of regular use.
Comfort and Carry Style
Carrying style directly impacts holster comfort and practicality. Holsters designed for inside the waistband (IWB) often prioritize low profile and ergonomics to prevent pressure points, while outside waistband (OWB) models focus more on ease of access. Appendix carry holsters usually have a slimmer, more contoured design to reduce bulk in front body area.
Weight and bulk affect how well you can move and conceal your firearm throughout the day. A bulky or heavy holster might cause shifting, discomfort, or printing under clothing. The right fit and shape reduce fatigue and make daily carry more manageable.
Small design choices, like rounded edges and adjustable clips, also contribute to comfort during extended wear.
Ease of Use and Accessibility
Drawing comfortably without snagging on clothing or holster components is a clear indicator of well-designed construction. Smooth edges and a design that keeps the optic exposed for sighting make it possible to aim quickly right after drawing.
Blocked sights or catch points can ruin fast target acquisition in real scenarios.
Reholstering safety is just as important as drawing. The holster should allow the firearm to slide back in easily without forcing an awkward angle but still retain securely once seated. Secure reholstering reduces risk of dropping the gun or causing accidental discharge due to difficult manipulation during stressful moments or while moving.
Proper Maintenance and Care for Your Sig P320 RX Holster
Keeping a Sig P320 RX holster in good condition means regular attention to both cleaning and inspection. Dirt and sweat can accumulate inside the holster, which may affect the retention and the finish of the gun.
Using a soft brush or a damp cloth helps remove debris without damaging the material. Avoid harsh chemicals, especially on leather, since they can dry out or crack the surface.
Check the holster’s retention frequently. The screws or clips that secure the holster often loosen with use and may need tightening. Retention that is too loose risks the firearm falling out, while too tight can make drawing slower.
- Clean the holster after every few uses.
- Apply leather conditioner if the holster is leather-based.
- Inspect all mounting components carefully.
Regular maintenance keeps your holster working reliably and prolongs its lifespan.
Common Mistakes to Avoid When Using a Sig P320 RX Holster
One frequent mistake with Sig P320 RX holsters is relying on improper retention settings. Having retention too tight can complicate a smooth draw and slow your reaction time. Conversely, weak retention increases the risk of the firearm falling out during movement.
Another common issue is incorrectly positioning the holster on the belt or waistband. A poorly placed holster can cause discomfort, printing (visibility under clothing), or reduced accessibility. Placement varies depending on body shape and clothing style, so experimentation is key.
- Do not force a draw if the firearm feels stuck.
- Avoid using oversized belts that affect holster stability.
- Don’t ignore wear signs on holster material or fasteners.
Taking time to adjust retention and placement can prevent these problems and improve daily carry experience.
Comparing Inside-the-Waistband and Outside-the-Waistband Holsters for the Sig P320 RX
Inside-the-waistband (IWB) and outside-the-waistband (OWB) holsters offer different advantages for carrying the Sig P320 RX. IWB holsters are worn inside the pants, which helps conceal the firearm more effectively. This makes them suitable for those wanting a discreet carry method, although they can feel less comfortable for long periods, especially in warmer climates.
OWB holsters attach outside the pants and offer faster access during a draw. They generally fit more securely and provide better comfort since they don’t press against the body, but require a longer shirt or jacket to avoid printing.
- IWB holsters tend to be better for concealment.
- OWB holsters are often favored for range or open carry.
- Choosing depends on lifestyle, clothing style, and how quickly access is needed.
Trying both holster types helps determine which suits your specific carry needs.
