Understanding Bianchi Fit Groups
Bianchi Fit Groups offer a unique sizing approach, differing from traditional methods. Identifying your firearm’s specific Fit Group is key to selecting a compatible holster.
What are Bianchi Fit Groups?
Bianchi Fit Groups represent a proprietary sizing system developed to accommodate the vast array of firearm models and their subtle variations. Unlike conventional holster sizing based solely on general firearm dimensions, Fit Groups consider the precise contours and specific features of each gun; This nuanced approach ensures a snug, secure, and reliable fit.
Each firearm is assigned to a specific Fit Group number, reflecting its unique profile. This system allows Bianchi to create holsters that perfectly cradle the firearm, maximizing retention and minimizing movement during carry. Understanding your firearm’s Fit Group is the foundational step in selecting the correct Bianchi holster.
How Fit Groups Differ from Traditional Sizing
Traditional holster sizing typically relies on broad measurements – length and width – offering a generalized fit. This method often necessitates adjustments or results in a less-than-ideal holster experience. Bianchi Fit Groups, however, move beyond these basic dimensions, accounting for specific firearm features like frame shape, slide profile, and accessory rails.
This detailed categorization provides a far more precise match, eliminating guesswork and ensuring optimal retention. While traditional sizing might accommodate a range of similar firearms, Fit Groups pinpoint the exact holster designed for your specific model, enhancing both security and comfort during carry.
Locating Your Firearm’s Fit Group
Determining your firearm’s Bianchi Fit Group is straightforward using the official Bianchi Holster Selector Chart. This chart, available as a downloadable PDF on the Bianchi website, lists firearms alphabetically and assigns each a unique Fit Group number. Carefully identify your exact firearm model – including any variations like barrel length or generation – to ensure accuracy.
Alternatively, you can utilize online resources and forums dedicated to Bianchi holsters, where users often share fit information. Remember, selecting the correct Fit Group is paramount for a secure and properly functioning holster.

Key Considerations for Holster Selection
Choosing a Bianchi holster requires considering your firearm model, desired carry style (IWB, OWB), dominant hand, and preferred cant angle for optimal comfort.
Firearm Model and Specific Variations
Precise firearm identification is paramount when selecting a Bianchi holster. Models with slight variations – differing barrel lengths, slide cuts, or accessory rails – necessitate distinct holster fits. Bianchi’s selector chart meticulously details compatibility, but confirming your exact firearm configuration is crucial.
Don’t assume a holster listed for a “Glock 19” will universally fit all G19 variants. Check for specific listings accommodating features like threaded barrels or optics. Incorrect assumptions lead to improper fit, compromising retention and safety. Always prioritize a snug, secure fit tailored to your specific firearm.
Carry Style (IWB, OWB, Shoulder, etc.)
Your chosen carry method significantly influences holster selection. Inside-the-waistband (IWB) holsters demand minimal bulk and ride close to the body, often requiring specific cant angles for comfort and accessibility. Outside-the-waistband (OWB) holsters offer greater versatility but may necessitate a larger holster size.
Shoulder holsters, less common, require a unique fit accommodating body movement. Bianchi offers models tailored to each style; the selector chart filters options accordingly. Consider your clothing, body type, and desired level of concealment when choosing a carry style and corresponding holster.
Dominant Hand and Cant Angle
Holster selection must account for your dominant hand – right or left. Bianchi offers mirrored holster designs for both, ensuring comfortable access. Equally crucial is the cant angle, the degree at which the holster tilts. A forward cant promotes a faster, more natural draw, particularly for IWB carry.
Adjustable cant options are available on some models, allowing customization. Consider your body type and draw style when determining the optimal cant angle. The Bianchi selector chart often indicates available cant adjustments for specific holsters, maximizing comfort and efficiency.

Popular Bianchi Holster Models & Sizing
Bianchi’s diverse lineup includes the Infinito CV Disc, Accumold, and Eclipse series; each requires specific sizing considerations for a secure, optimal fit.
Bianchi Infinito CV Disc – Sizing Notes (Limited Information)
The Bianchi Infinito CV Disc holster prioritizes comfort and concealability, but detailed sizing information is notably limited publicly. Users often rely on direct fit confirmation through Bianchi’s selector chart or contacting customer support. This model is known for its adjustable tension, potentially accommodating slight variations within a fit group. However, precise measurements are still crucial.
Due to the holster’s design, focusing on overall firearm dimensions—length, width, and slide thickness—is paramount. It’s essential to verify compatibility before purchase, as the Infinito CV Disc’s unique construction may not universally fit all listed firearms within a given group. Thorough research is highly recommended.
Bianchi Accumold Series – Fit Group Recommendations
The Bianchi Accumold series, renowned for its durable molded construction, generally follows Bianchi’s established Fit Group system. However, due to the series’ broad range of models, specific recommendations vary. Consulting the official Bianchi holster selector chart is crucial for accurate sizing.
Many Accumold holsters accommodate multiple Fit Groups, offering versatility. Users should prioritize their firearm’s exact model and any aftermarket modifications when selecting a size. Proper fit ensures secure retention and safe carry. Always double-check compatibility before finalizing a purchase to avoid potential issues.
Bianchi Eclipse Series – Size Chart Specifics
The Bianchi Eclipse series, known for its minimalist design and secure fit, requires careful attention to the official Bianchi size charts. Unlike some series with broader Fit Group compatibility, the Eclipse often demands a precise match.
Users should meticulously compare their firearm’s specifications – including slide length, width, and thickness – against the chart’s detailed measurements. Variations within a firearm model can necessitate different Eclipse sizes. Prioritize downloading the specific PDF chart for your chosen Eclipse model for the most accurate guidance.

Measuring Your Firearm for a Precise Fit
Accurate measurements of length, width, and slide thickness are crucial for selecting the correct Bianchi holster. Consider any modifications or accessories attached;
Measuring Length and Width
Precise length and width measurements are foundational for a secure Bianchi holster fit. Begin by measuring the overall length of your firearm, from the muzzle to the back of the grip. Utilize a ruler or calipers for accuracy, ensuring a straight measurement.
Next, determine the width at the widest point, typically the slide or frame. Again, calipers offer superior precision. Record both measurements carefully, as even slight discrepancies can impact holster compatibility. These dimensions are key inputs when consulting the Bianchi fit charts and selecting the appropriate holster model for your specific firearm.
Measuring Slide Thickness
Accurate slide thickness measurement is crucial, especially for concealed carry holsters, impacting draw speed and comfort. Use digital calipers to measure the slide’s thickness at its midpoint. Ensure the calipers are perpendicular to the slide surface for a precise reading.
This measurement dictates how closely the holster will conform to the firearm, influencing retention and preventing looseness. Note that aftermarket modifications, like optic cuts or compensators, will alter slide thickness; measure accordingly. Refer to Bianchi’s charts, as they often specify slide thickness ranges for optimal fit.
Considering Modifications and Accessories
Firearm modifications significantly impact holster fit. Aftermarket accessories like optics, compensators, lasers, or extended magazine releases alter the gun’s dimensions. Always account for these changes when selecting a Bianchi holster.
A holster designed for a stock firearm may not accommodate modifications. Check Bianchi’s fit charts for specific notes regarding compatible accessories. If unsure, contact Bianchi’s customer support for guidance. Failing to consider modifications can lead to a poor fit, compromising safety and retention, potentially causing malfunctions during critical use.

Troubleshooting Fit Issues
Addressing fit problems ensures optimal holster performance and safety. Common issues include holsters being too tight or loose, requiring adjustments to retention for a secure draw.
Holster Too Tight
If your firearm struggles to enter or exit the Bianchi holster, it’s likely too tight. Initially, avoid forcing the gun, as this could damage both the holster and the firearm. Inspect the holster for any obstructions or debris that might be contributing to the issue.
For leather holsters, gentle manipulation and working the firearm in and out repeatedly may gradually stretch the leather. Kydex holsters, being less pliable, often require adjustment via screws or heat molding (consult Bianchi’s resources for specific model instructions).
Ensure you’ve selected the correct Fit Group for your exact firearm model, including any modifications. A too-tight holster compromises a quick, safe draw and can lead to wear and tear.
Holster Too Loose
A Bianchi holster that’s too loose presents significant safety concerns, potentially allowing the firearm to move excessively or even fall out during activity. Immediately cease carrying if the gun exhibits excessive play within the holster. Check that you’ve confirmed the correct Fit Group for your firearm model.
For leather holsters, consider using a holster conditioner to help the leather conform more snugly to the gun. Kydex holsters often feature adjustable retention screws; tighten these incrementally to achieve a secure fit.
Never modify the holster structurally; always adhere to Bianchi’s recommended adjustments.
Adjusting Retention
Bianchi holsters often offer adjustable retention, allowing users to fine-tune the security of their firearm. Kydex models frequently utilize screws to control the tension, tightening for a firmer grip and loosening for quicker draws. Leather holsters rely on the natural molding process; consistent carry shapes the leather over time.
Adjust retention incrementally, testing the draw each time to ensure a balance between security and accessibility. Avoid over-tightening, which can hinder a swift, emergency draw. Regularly inspect adjustment screws for tightness.

Bianchi Holster Materials and Their Impact on Fit
Material choice significantly impacts fit; leather stretches and molds, Kydex offers rigidity, and nylon provides flexibility. Understanding these properties ensures optimal holster selection.
Leather Holsters – Stretch and Molding
Bianchi’s leather holsters are renowned for their ability to conform to the firearm over time, creating a custom fit. This “break-in” period involves the leather stretching and molding around the gun’s contours. Initially, a snug fit is common, but with consistent use, the holster will adapt.
The quality of the leather directly influences this process; higher-grade leather molds more effectively and retains its shape better. Factors like humidity and body heat accelerate the molding process. It’s crucial to ensure a secure retention even after molding, preventing accidental dislodgement. Regular conditioning helps maintain the leather’s flexibility and prevents cracking.
Kydex Holsters – Rigidity and Precision
Bianchi’s Kydex holsters offer a distinctly different fit experience compared to leather. Kydex is a thermoplastic known for its rigidity and exceptional durability. These holsters are typically molded to the specific firearm model, providing a precise and consistent fit right out of the package.
Unlike leather, Kydex doesn’t stretch significantly, ensuring reliable retention. Adjustments, if needed, often involve modifying the screws that control tension. This precision minimizes movement and maximizes security. Kydex holsters excel in environments demanding consistent performance and robust protection for the firearm.
Nylon Holsters – Flexibility and Adjustability
Bianchi nylon holsters present a versatile option, prioritizing flexibility and adjustability. Constructed from durable nylon materials, these holsters often feature adjustable retention straps and belt loops, accommodating various carry preferences and firearm sizes. They are generally lighter weight than leather or Kydex alternatives.
Nylon’s inherent flexibility allows for a more adaptable fit, particularly beneficial for individuals seeking comfort during extended wear. While not as rigidly precise as Kydex, nylon holsters offer a balance between security, comfort, and ease of adjustment for diverse needs;

Magazine Holder Sizing with Bianchi
Bianchi magazine holders should align with your holster’s Fit Group for optimal compatibility and retention. Adjustable options provide a customized carry experience.
Matching Magazine Holders to Holster Fit Groups
Ensuring compatibility between your Bianchi holster and magazine holders is paramount for a functional and secure carry system. Bianchi designs magazine pouches to correspond with specific Fit Groups, mirroring the sizing used for their holsters. This alignment guarantees a consistent and reliable fit, preventing unwanted movement or accidental dislodgement of your magazines during activity.
When selecting magazine holders, always refer to the Bianchi holster selector chart and identify the Fit Group of your chosen holster. Then, choose magazine pouches specifically designated for that same Fit Group. This meticulous approach ensures a harmonious integration, enhancing both comfort and operational efficiency.
Double Magazine Pouch Considerations
When opting for a Bianchi double magazine pouch, careful consideration of firearm and magazine dimensions is crucial. These pouches generally accommodate two magazines of the same size and type, so ensuring compatibility with your specific firearm’s magazines is essential. Verify the Fit Group designation for both the pouch and your holster to maintain a streamlined carry system.
Double pouches offer increased capacity but can add bulk. Assess your carry style and comfort preferences. Consider the weight distribution and how it impacts your overall mobility. Proper adjustment of retention devices is vital to prevent accidental magazine loss while maintaining quick access.
Adjustable Magazine Holders
Bianchi offers adjustable magazine holders providing versatility for various magazine sizes and user preferences. These often feature adjustable tension screws or straps, allowing a customized fit for secure retention. Regularly check and tighten these adjustments to prevent magazine slippage during movement or activity.
Adjustability is particularly beneficial when using different magazine types or when accommodating slight variations in magazine dimensions. Ensure the adjustment doesn’t compromise quick access to the magazines when needed. Proper adjustment balances security and speed, crucial for practical applications.
