You made a serious choice when you picked up a SIG Sauer. Whether you went with the modular genius of the P320 or the capacity-defying magic of the P365, you clearly value innovation and reliability.
But here is the hard truth. Even the best firearm in the world becomes a liability if you shove it into a subpar holster. It is like parking a Ferrari in a carport during a hail storm. It just doesn’t make sense.
Finding the right carry system is not just about comfort. It is about safety, speed, and confidence. You need a rig that matches the engineering excellence of your pistol. That is where a dedicated, precision-molded Kydex holster comes into play.

At Eclipse Holsters, we build holsters worthy of your SIG Sauer investment. This guide covers selecting the right configuration for your model, understanding material benefits, and recognizing what separates professional-grade carry gear from compromised alternatives.
Why Your SIG Sauer Demands More Than Generic Solutions
SIG Sauer earned its reputation through rigorous testing and proven performance. The ultra-compact P365 revolutionized micro-compact capacity, while the P320 won the U.S. Army's Modular Handgun System competition in 2017. That engineering deserves holsters built to matching standards.
Generic holsters assume close enough works. They use oversized molds to fit multiple firearms, meaning your SIG sits in a shell designed for nothing specific. The P365's slim 1-inch width gets lost in holsters meant for thicker frames. The P320's unique trigger guard geometry doesn't interface properly with retention systems molded from different pistols.
Loose fit creates tangible problems. Your firearm shifts position during movement, changing draw stroke mechanics and making muscle memory unreliable. The gun rattles inside the holster, broadcasting your concealed status. Inconsistent retention means you're either fighting excessive resistance or worrying about retention during physical activity.
Eclipse's SIG Sauer holsters take the opposite approach. We mold each holster using actual SIG firearms, capturing the precise trigger guard dimensions, slide profiles, and frame contours that make your model unique. A holster molded from a P365XL fits that gun perfectly because it was formed around that exact configuration.
The result is retention that works with your firearm's design. Your SIG locks into place with consistent pressure, releases cleanly when you establish your grip, and maintains that performance through thousands of repetitions.
The P365 Platform: Micro-Compact Meets Holster Engineering
The P365 changed expectations for micro-compact pistols. Before SIG introduced this model, carriers chose between capacity and concealability. The P365 packs 10+1 rounds into a package barely larger than traditional six-shot subcompacts. The XL variant extended capacity while adding optics compatibility. The X-Macro pushed further with 17+1 capacity in a concealable package.
Each variant creates specific holster requirements. The standard P365's compact grip length excels for appendix carry, but that shortened profile demands holsters engineered to prevent odd printing angles. The XL's extended slide changes the balance point, requiring different cant and ride height optimization. The X-Macro's increased grip capacity means more material against your body, making sweat guard design critical.
Your SIG Sauer Kydex holster must address these dimensional realities. The P365's slim width seems like it would simplify holster design, but that minimal footprint actually requires more precise molding. Any extra material adds bulk that defeats the compact's concealment advantage.
Many P365 owners add tactical lights to their setup. Standard holsters won't accommodate these additions. Eclipse offers light-bearing configurations specifically molded for P365 models with lights, ensuring your equipped firearm gets the same precision fit as the base model.
Concealment demands more than just a small holster. The P365's short barrel means the muzzle end sits closer to your belt line, which can create pressure points without proper design. Quality P365 holsters incorporate adjustable cant to fine-tune how the grip sits against your body, and ride height adjustment to optimize the draw stroke.
The P320 Series: Modular Design Requires Specific Solutions
The P320's fire control unit transfers between grip modules of different sizes, letting users configure one pistol for multiple roles. That versatility has made it popular with professional and civilian carriers, but creates holster selection challenges.
Understanding P320 variants matters. The Compact offers concealability without sacrificing capacity. The Full Size provides duty-ready capability. The X-Carry bridges both worlds with enhanced ergonomics and optics-ready slides. Specialized variants like the M17 and M18 adopted by the U.S. military feature specific dimensions.
Each variant's grip module determines holster compatibility more than any other factor. The Compact's shorter grip conceals differently than the Full Size's extended frame. When manufacturers claim their holster fits all P320 variants, they're admitting it fits none properly.
Professional users carrying P320s for duty face different priorities than concealed carriers. Duty holsters must retain the weapon through physical confrontations while allowing rapid presentation. Many duty P320s run weapon-mounted lights. Eclipse offers holsters configured for these setups, molding around both the pistol and the light to maintain proper retention.
The P320's optics-ready variants add another consideration. Red dot sights change the slide's profile, requiring holsters with proper sight clearance. Properly engineered holsters maintain tight tolerances around the slide while providing clearance for your specific optic.
The P320's modularity means many owners swap grip modules based on carry context. Your holster should match the configuration you actually carry. A holster formed around your Compact grip module won't properly retain a Full Size configuration, creating security risks no responsible carrier should accept.
Beyond the Mainstream: Holsters for Classic SIG Models
The P365 and P320 dominate current attention, but SIG's legacy models still serve thousands of carriers. The P226 defined what full-size service pistols should deliver, serving military and law enforcement worldwide. The P229 offered similar reliability in a compact package.
The P226's full-size frame and metal construction create different carry requirements than polymer striker-fired models. Weight distribution matters more with all-metal pistols. The decocker's position and hammer's profile require proper clearance in holster design.
Compact models like the P228 and M11-A1 bring full-size capability to more concealable packages. The M11-A1 features specific dimensions that differ from commercial P229 variants despite superficial similarities.
The P238 and P938 serve the pocket pistol market with 1911-style controls in modern compact packages. Both require holsters that accommodate their single-action operating system, including the external safety and exposed hammer.
Eclipse manufactures holsters for these classic models because we understand they still serve vital roles. Whether you're carrying a P226 for duty or a P938 for concealed backup, your holster should deliver the same precision fit as those built for newer models.
Why Kydex® is the Superior Choice for SIG Sauer Pistols
Material selection directly impacts holster performance. For SIG Sauer pistols, Kydex offers advantages other options can't match. This thermoplastic maintains its precisely molded shape permanently, meaning your holster's retention stays consistent through years of daily carry.
Leather holsters absorb moisture from sweat, which contacts your pistol's finish. SIG's Nitron and stainless finishes resist corrosion well, but why expose them unnecessarily? Leather also stretches and deforms over time, changing retention unpredictably. Your draw stroke becomes less reliable as the holster ages.
Kydex's rigid structure provides benefits beyond shape retention. The material's smooth interior allows clean draws without excessive friction. Your SIG's finish won't show premature wear from daily holster use. The rigidity maintains holster mouth integrity, enabling safe one-handed reholstering. Under stress, when fine motor skills deteriorate, you need equipment that works despite compromised technique.
Temperature stability matters for carry gear. Kydex maintains consistent performance from winter cold to summer heat. Leather stiffens in cold weather and becomes excessively pliable in heat. Nylon holsters lack structural rigidity necessary for reliable retention. Kydex works regardless of environmental conditions.
Maintenance stays minimal. Periodic cleaning with soap and water removes accumulated lint and debris. No conditioning, no weatherproofing, no special storage requirements. Your holster functions the same whether stored for months or used daily.
Quality Kydex holsters withstand tens of thousands of draw cycles without meaningful degradation. Scratches and scuffs that would compromise other materials barely mark properly manufactured Kydex.
The Eclipse Difference: Precision Engineering for Your SIG
Manufacturing excellence starts with using actual firearms for molding. Eclipse forms each SIG Sauer holster around real pistols, capturing every dimension that matters for retention and function. We don't approximate your P365's trigger guard or estimate your P320's slide profile. We mold directly from the gun itself.
This precision matters most at the retention interface points. Your SIG locks into the holster through specific contact areas around the trigger guard and frame. Generic holsters create these interfaces based on averaged dimensions across multiple firearms. Eclipse establishes them from your exact model, resulting in retention that's simultaneously secure and accessible.
Quality control extends beyond initial molding. Every holster undergoes inspection to verify proper fit, retention characteristics, and finish quality. Edge work receives particular attention, as rough edges create discomfort and potential clothing damage. We chamfer every edge and smooth all contact points before shipping.
Our custom builder gives you control over your holster's configuration. Choose your carry style between inside the waistband and outside the waistband. Select from more than 90 material colors and patterns.
These customization options let you optimize the holster for your specific carry context. Professional users requiring duty retention want different mounting than concealed carriers prioritizing comfort. Eclipse accommodates these varying needs rather than forcing you to adapt to predetermined configurations.
American manufacturing matters for quality control and customer support. When issues arise or questions develop, you're communicating with the people who built your holster. We stand behind every product with a lifetime guarantee because we know our manufacturing process produces equipment that lasts.
Matching Your Carry Style to Your SIG Holster
Your preferred carry method influences holster selection as much as your firearm model. Understanding how different positions interact with various SIG models helps you choose configurations that enhance rather than compromise carry effectiveness.
Inside the waistband carry remains the most popular choice for concealed carry, particularly for compact SIG models like the P365 and P320 Compact. IWB placement naturally conceals the pistol behind clothing while keeping it accessible. Your holster's cant angle determines how the grip sits against your body.
Appendix carry has gained substantial popularity. It provides fast access, excellent concealment, and works well with vehicle carry where behind-the-hip positions become uncomfortable. SIG's compact models excel in appendix carry, but holster design must address the position's specific challenges.
Strong-side carry around the 3 to 4 o'clock position offers comfortable all-day carry for many users. Full-size SIG models like the P226 or P320 Full Size work well here, as the body's natural contours help conceal increased dimensions.
Outside the waistband holsters serve both open carry and situations where deep concealment isn't necessary. OWB placement keeps the pistol's weight off your waistline, distributing it through the belt instead. This proves more comfortable for all-day carry of larger SIG models.
Light-bearing configurations require holsters specifically designed to accommodate your weapon-mounted light. Eclipse molds light-bearing holsters around your SIG equipped with its specific light, maintaining proper retention characteristics while protecting the light from damage.
Frequently Asked Questions
Can I use the same holster for my P365 and P365XL since they're the same platform?
No, the P365 and P365XL have different slide and overall lengths despite sharing the same platform. The XL's extended slide changes the holster's required dimensions and balance characteristics. Using a holster molded for the standard P365 with an XL creates loose retention at the muzzle end. Eclipse molds holsters specifically for each variant to ensure proper fit across the entire firearm's length.
Do I need a different holster if I add a red dot sight to my P320?
It depends on the holster's design. Many Eclipse holsters include adequate sight clearance to accommodate red dot optics without requiring a different model. However, some optics have larger footprints that may require verification. You can confirm compatibility for your specific optic using our custom builder tool. Properly designed optic-ready holsters maintain retention around the slide and frame without compromising clearance for your sight.
Is Kydex comfortable for all-day carry?
Yes. While Kydex is rigid, comfort comes from the design. By spreading the weight across the belt clips and removing sharp edges, an Eclipse holster disappears on the body. Many of our customers carry their SIGs for 12+ hours a day without issue.
