Description
The TacStar SideSaddle is a straightforward solution for keeping shotgun shells within arm's reach. It bolts directly to the side of your Mossberg 500, 590, or 600 receiver using the included hardware, and the installation takes around ten minutes with no modifications to your shotgun required.
Design Built for Real-World Use
This 4-round carrier uses a durable polymer shell holder mounted on an aluminum backing plate. The polymer construction is undersized just enough to create spring tension that grips shells securely whether you load them brass-up or brass-down. The aluminum plate is engineered to sit flush on your receiver without interfering with long forends, which makes it compatible with most shotgun configurations out of the box. The whole package weighs less than a pound and won't slow you down or throw off your shotgun's balance.
A Proven Design with Staying Power
TacStar has been producing SideSaddles for decades, and this particular design shows up on hunting shotguns, patrol weapons, and range guns because it simply works. The polymer material resists weather and corrosion, and the simple mechanical design means there's nothing fancy that can break. Shells stay put during recoil, and the carrier sits securely once installed. If you're stepping up from carrying shells in your vest pocket or jacket, you'll notice the difference immediately in terms of speed and convenience.
What to Expect During Install
Mount the aluminum plate to your receiver using the bolts provided in the package. On most Mossberg 500 and 590 models, these screws replace factory fasteners without any drama. Some field-grade shotguns with longer forends may require a small modification to clear the saddle during operation, but tactical forends and most newer models install without touching anything else. Once mounted, the polymer carrier slides onto the aluminum plate and is secured with additional screws.

Frequently Asked Questions
Do I need a gunsmith to install the TacStar SideSaddle on my Mossberg 500?
No. The SideSaddle mounts directly to your receiver using included hardware and takes about ten minutes to install. Most Mossberg 500 and 590 models bolt it on without any modifications. Some field-grade shotguns with longer forends may require a small forend modification, but tactical forends and the TacStar pistol grip forend work without any changes.
Will the 4-round SideSaddle work if my shotgun has a long forend?
The 4-round SideSaddle is specifically designed to provide clearance for long forends that might interfere with a 6-round model. If you already have a long wood forend, this is the better choice. Just double-check that the forend doesn't overlap the carrier when fully extended.
Can I load shells brass-up or brass-down in the carrier?
Yes. The polymer shell holder creates spring tension that holds shells securely in either orientation, so load it whichever way works best for your grip and draw preference.
Will this SideSaddle fit on a Mossberg 500 or 590 with a pistol grip stock?
Yes. The SideSaddle mounts to the receiver, not the stock, so it works with any stock configuration including pistol grip models. Shotguns with the TacStar tactical forend or pistol grip forend install without any additional modifications.
