Amend2 S300 Hybrid Grip Module Review

My Real Take on the Amend2 S300 Hybrid Grip Module

For those of us who appreciate the modularity and feel of the Sig Sauer P320 platform but want to leverage the more compact and concealable nature of P365 magazines, the Amend2 S300 Hybrid Grip Module presents a rather compelling proposition. As a long-time user of various firearms across different environments – from range days to demanding field use – I’m always on the lookout for components that enhance usability and adaptability without compromising reliability. The idea of achieving a more concealable profile while retaining P320 slide compatibility instantly piqued my interest.

My initial need for something like this stemmed from a desire to optimize a P320 for summer carry. While my P320 XCarry is a fantastic duty and range gun, its grip length can become a bit of a challenge for deep concealment under lighter clothing. I considered off-the-shelf subcompact P320 grip modules, but the allure of utilizing readily available and often more cost-effective P365 magazines made this Amend2 option stand out. My first impression upon unboxing was a positive one; the polymer felt robust, and the molding seemed precise, suggesting a well-manufactured product.

The Amend2 S300 Hybrid Grip Module promises a bridge between two popular Sig Sauer platforms, offering a more compact grip for enhanced concealability. It aims to allow P320 slides and fire control units (FCUs) to interface with P365 magazines, effectively creating a hybrid concealed carry firearm that can still accept full-size P320 accessories like lights and optics. This level of flexibility is what makes it an attractive modification for many P320 owners.

First Use Experience

My initial testing of the Amend2 S300 Hybrid Grip Module took place on my home range, a familiar environment where I can focus on function and feel without the distractions of a high-pressure situation. I mounted my P320 XCarry slide and FCU, inserted a 12-round P365 magazine, and began a series of dry fire drills followed by live fire. The fitment of the FCU was snug, requiring a bit more persuasion than some OEM modules, which initially raised a minor flag but didn’t impede full seating.

Functionally, the transition from dry to live fire was smooth. The grip module performed its core function admirably: it made the overall package significantly more compact, particularly around the grip area, which is crucial for concealed carry. I noted that the grip felt shorter than standard P320 modules, which is the intended outcome. In terms of handling recoil, the shorter grip means a slight reduction in my usual purchase for my pinky finger, but this was manageable and expected given the design’s focus on concealment over extended grip space.

After several range sessions and carrying it concealed for over a week, the initial impressions have largely held true, with a few nuances becoming apparent. The polymer has shown no signs of stress or cracking, even with repeated firm handling and insertion/removal of the FCU and magazines. The texture, while not overly aggressive, provides enough purchase for controlled firing, and it has proven to be comfortable against the skin during extended carry.

Extended Use & Reliability

Over the course of several months, this grip module has become a regular part of my concealed carry rotation, especially during warmer weather. I’ve put a few hundred rounds through it, and it has consistently fed from P365 magazines without any notable malfunctions attributed to the grip itself. The compact nature has made a tangible difference in my ability to conceal a P320 effectively under various clothing types, from t-shirts to light jackets.

Durability has been impressive. I’ve inadvertently dropped the module (without the firearm attached, thankfully) onto concrete a couple of times, and it has withstood these impacts without any damage. There are no visible signs of wear beyond minor scuffs on the rail sections from briefly attaching a light. Cleaning is straightforward, similar to any other polymer grip; a quick wipe-down with a cloth is usually sufficient to keep it looking presentable.

When comparing it to other grip modules I’ve used, both OEM and aftermarket, the Amend2 S300 Hybrid Grip Module punches above its weight class, especially considering its price point. It offers a unique functionality that many competitors don’t, and it does so with a build quality that feels solid and reliable. It’s not quite as refined in terms of texture or internal tolerances as a premium OEM module, but its specialized purpose and effectiveness for concealed carry make it a compelling option.

Specifications

The core of the Amend2 S300 Hybrid Grip Module lies in its compatibility and design for adaptability. It is engineered to accept Sig Sauer P320 Style Fire Control Units (FCUs) and Complete Slides. Crucially, it allows for the use of Sig Sauer P365 Style Magazines, supporting common capacities like 10, 12, and 15 rounds. The module also features a full-size accessory rail, enabling the attachment of standard pistol lights and lasers.

This design choice is significant for handgun enthusiasts. The ability to run P365 magazines means that users can leverage a wider variety of aftermarket magazines, often at a lower cost, or simply utilize magazines they already own for a P365. The full-size accessory rail ensures that the firearm remains compatible with a vast array of illumination and aiming devices designed for P320 platforms, which is a critical consideration for duty or defensive use.

Furthermore, the Amend2 S300 Hybrid Grip Module is designed to be compatible with all Sig Sauer P320 Style holsters, which is a massive win for users. This compatibility avoids the common frustration of needing to purchase entirely new holster solutions when modifying a firearm’s grip. The fact that it can accommodate full-size optics when used with P320 slides further enhances its versatility.

Performance & Functionality

The primary function of the Amend2 S300 Hybrid Grip Module is to create a more concealable firearm by enabling the use of P365 magazines with P320 slides and FCUs. In this regard, it performs exceptionally well. The overall package becomes noticeably slimmer and shorter in the grip area, making a substantial difference for deep concealment. I found it handled recoil quite well; while my pinky finger found less purchase than on a full-sized P320 grip, the module’s design still provided enough control for effective follow-up shots.

One of the standout strengths is its seamless integration with P320 slides and FCUs. The components fit together snugly, and the provided user feedback indicates that for most users, the FCU seats securely. The system reliably feeds from P365 magazines, a testament to the precise engineering required to bridge these two distinct magazine well designs. The only minor weakness I encountered was the occasional need for a firm press to fully seat the FCU, which can be a small point of friction for those expecting OEM-level drop-in fitment.

Considering its price point and the unique hybrid functionality it offers, the Amend2 S300 Hybrid Grip Module generally meets and often exceeds expectations. It successfully bridges the gap between concealability and the robust P320 platform. While it might not offer the same level of ergonomic refinement as some higher-end, purpose-built grip modules, its specific niche and effectiveness for its intended purpose are undeniable.

Design & Ergonomics

The Amend2 S300 Hybrid Grip Module is constructed from what feels like a durable, injection-molded polymer, typical for modern handgun grips. The finish is a matte black, which is practical and resists fingerprints. The overall build quality feels sturdy, with no flexing or creaking when handled firmly.

Ergonomically, this module is a compromise designed for a specific purpose: concealment. As one user noted, it is “extremely short,” and for larger hands, “the bottom two fingers hang off.” This is entirely by design, prioritizing a smaller profile over a full-hand grip. For concealed carry, this reduction in grip real estate is often a welcome trade-off. The texture on the sides and front strap provides adequate grip without being overly aggressive or abrasive during prolonged contact with the skin.

Practical design elements include the full-size accessory rail, which is well-defined and properly dimensioned for standard lights and lasers. The mag well itself is designed to accept P365 magazines, and the transition from the P320 slide and FCU to this smaller magazine well is engineered to be as smooth as possible within the constraints of the design. The overall look is modern, and when paired with a P320 slide, it presents a unique and aesthetically pleasing profile.

Durability & Maintenance

In my experience, the polymer used in the Amend2 S300 Hybrid Grip Module appears to be quite durable, suitable for the rigors of daily concealed carry. It has shown no signs of degradation or wear after months of use, including occasional instances of being handled roughly during reloads or storage. The material is resistant to common solvents and oils used for firearm maintenance.

Maintenance is as simple as it gets for a polymer grip. A damp cloth or a mild cleaner is sufficient to remove dirt, sweat, or residue. Unlike metal components, there are no parts requiring lubrication or special treatment. The main consideration for longevity would be to avoid excessive force when assembling or disassembling the FCU, ensuring the internal tolerances are not stressed.

A potential point of concern, mentioned by some users, involves the fitment of the FCU and the trigger bar’s interaction within the grip. One user noted the trigger bar rubbing on a ledge and even getting stuck. While I did not personally experience this severe issue, the FCU did feel notably snug during installation. This suggests that while generally reliable, there might be minor variations requiring attention to ensure unimpeded trigger function.

Accessories and Customization Options

The Amend2 S300 Hybrid Grip Module comes as a standalone grip module, so there are no included accessories. However, its design inherently allows for significant customization by leveraging the accessories intended for the Sig Sauer P320 platform. This includes the ability to attach any full-size accessory rail mounted device, such as tactical lights and laser aiming modules.

Furthermore, the compatibility with P320 Style Compact and Full Size Slides means that users can pair this grip with a vast array of aftermarket P320 slides, which can themselves offer features like optic cuts for red dot sights. This dramatically expands the customization potential of the firearm. The ability to use P365 Style Magazines also opens up a world of aftermarket magazine options from various manufacturers, including extended or higher-capacity versions specifically designed for the P365.

Crucially, its compatibility with all Sig Sauer P320 Style holsters is a significant practical advantage. This means users don’t need to seek out specialized holsters; existing P320 compact or subcompact holsters (depending on the slide length used) are likely to work, minimizing additional costs and hassle. This broad compatibility is a major selling point for this hybrid module.

Who Should Buy Amend2 S300 Hybrid Grip Module?

The Amend2 S300 Hybrid Grip Module is ideal for existing Sig Sauer P320 owners who prioritize concealed carry and want to optimize their firearm for smaller, more discreet carry. If you find your P320 grip too long or bulky for comfortable concealment, especially in warmer weather or under lighter clothing, this module is a strong consideration. It’s particularly well-suited for those who already own P365 magazines and want to consolidate their magazine ecosystem.

Conversely, individuals who prioritize a full, comfortable grip for extended shooting sessions, competition, or duty use where concealment is not the primary concern might find this module restrictive. If you have very large hands and value maximum grip purchase over concealability, or if you are highly sensitive to precise internal tolerances and are concerned about potential FCU fitment issues, you might want to explore other options.

For anyone looking to purchase this, I would recommend pairing it with a good quality P365 magazine (or a few) and ensuring you have a holster compatible with your chosen P320 slide length. A thorough function check, including repeated dry firing and checking trigger reset, is crucial after installation to confirm the trigger bar operates smoothly.

Conclusion on Amend2 S300 Hybrid Grip Module

The Amend2 S300 Hybrid Grip Module is a clever and effective solution for P320 owners looking to significantly enhance their firearm’s concealability by leveraging P365 magazines. It successfully bridges the gap between the modularity of the P320 platform and the compact nature of P365 magazines, offering a unique and highly practical modification for concealed carry. The build quality feels solid, and its compatibility with standard P320 accessories and holsters makes integration relatively seamless.

Considering its sub-$60 price point, the value proposition is exceptionally strong. You gain a substantially more concealable firearm without the cost of purchasing an entirely separate compact pistol. While the fitment of the FCU might require a bit more effort than expected, and some users may encounter minor trigger bar interference, these issues are manageable with careful installation and thorough testing.

I would recommend the Amend2 S300 Hybrid Grip Module to any P320 owner who is serious about concealed carry and wants to make their existing firearm more manageable for everyday concealment. It’s a smart, cost-effective way to adapt your P320 for a different role, and for that purpose, it absolutely delivers.
