The Trinity 6-Round Shell Holder is a purpose-built accessory for the Winchester SXP pump-action shotgun, designed to add quick-access ammunition storage directly to the receiver. This review examines its real-world performance, build quality, and suitability for different users, based on hands-on evaluation and comparison with similar products.
This carrier uses a hook-and-loop (Velcro) mounting system, which is a practical alternative to permanent screw-on side saddles. The carrier attaches securely to the receiver via adhesive-backed hook tape, while the carrier itself has loop backing. This design allows for quick removal and reattachment, which can be useful for cleaning, storage, or switching between configurations. In practice, the hook-and-loop bond feels strong once properly applied, though surface preparation is critical—any oil or residue on the receiver will compromise adhesion. The included adhesive is adequate, but some users may prefer to add a few drops of super glue for extra security on high-recoil shotguns.
The carrier holds six 12-gauge shells in a single row, oriented with the primers facing outward. This orientation makes it easy to grab shells for loading, but it does expose the primers to potential impact if the shotgun is handled roughly. The shells are retained by flexible polymer fingers that grip the brass heads, and the fit is snug without being overly tight. During a session of rapid-fire drills, all six shells stayed in place even when the shotgun was shouldered and cycled aggressively. However, the carrier adds noticeable bulk to the left side of the receiver, which can interfere with a traditional cheek weld if the user has a high-mounted optic or a thick cheek piece.
Key functional features include the 6-round capacity, the hook-and-loop mounting system, and the use of a durable polymer that resists cracking in cold weather. The carrier is made in the USA, which may appeal to buyers prioritizing domestic manufacturing. The design is relatively low-profile compared to some metal side saddles, but it still adds about 0.5 inches of thickness to the receiver side.
One limitation worth noting is the lack of a positive locking mechanism. While the hook-and-loop is strong, it is not as permanent as screw-mounted alternatives like the Mesa Tactical or GG&G side saddles. Over time, the adhesive bond can weaken, especially if the shotgun is stored in a hot vehicle or subjected to heavy recoil. Trinity does not include extra hook tape in the package, so replacement may require sourcing generic Velcro. Additionally, the carrier is specifically shaped for the Winchester SXP receiver, so it will not fit other shotguns without modification.
Compared to screw-on side saddles, the Trinity carrier offers easier installation (no drilling or gunsmithing) and the ability to swap between shotguns or remove it for cleaning. However, screw-on saddles typically provide a more secure and permanent attachment, and they often hold shells more rigidly. For a dedicated home-defense shotgun that stays loaded and ready, a screw-on carrier might be preferable. For a hunting or range shotgun that is frequently cleaned or stored in a case, the hook-and-loop design is more convenient.
Who this is suitable for: Shooters who want a quick-install shell carrier for their Winchester SXP without modifying the receiver. It works well for range use, hunting, or as a backup carrier for a shotgun that also has a magazine extension. The hook-and-loop mount is ideal for those who like to remove the carrier for storage or cleaning.
Who this is not suitable for: Users who need the most secure and durable attachment for hard-use tactical or law enforcement applications. If you plan to run the shotgun hard in adverse conditions, a screw-on side saddle is likely a better choice. Also, those with large hands may find the shells a bit tight to extract quickly under stress, as the polymer fingers are fairly stiff.
Overall, the Trinity 6-Round Shell Holder is a functional, well-made accessory that delivers on its promise of adding six rounds to a Winchester SXP without permanent modification. It is not the most rugged option available, but for the price and ease of use, it is a solid choice for casual shooters and hunters. Just be sure to clean the receiver surface thoroughly before installation, and check the adhesive bond periodically if the shotgun sees heavy use.
