The Ruger GP100 is a renowned revolver prized for its reliability and accuracy. Adding a red dot sight can significantly enhance its performance, particularly for target shooting, hunting, or self-defense. However, choosing and installing the right red dot mount for your GP100 requires careful consideration. This guide explores the various options, factors to consider, and best practices for mounting a red dot on your Ruger GP100.
Understanding Ruger GP100 Red Dot Mount Options
Several manufacturers offer red dot mounts specifically designed for the Ruger GP100. These mounts vary in design, material, and mounting method. The most common types include:
1. Weaver Rail Mounts:
These mounts attach to the Ruger GP100 via a rail system, usually requiring drilling and tapping of the revolver's frame. This is a permanent modification and should only be undertaken by experienced gunsmiths. While offering a sturdy platform, this method permanently alters the firearm. Consider the implications carefully before proceeding. This option provides the most robust and stable mounting solution.
2. Top-Mount Adapters:
These adapters sit atop the rear sight of the GP100, eliminating the need for permanent modifications. They are often less expensive and easier to install than rail mounts. However, they might affect the sight picture and can be less stable than rail mounts, especially during recoil. The height of the red dot above the bore axis is also a critical factor to consider here, potentially impacting point of aim/point of impact.
3. Scope Mounts:
While not strictly red dot mounts, some scope mounts designed for revolvers can accommodate red dot sights. These mounts generally attach to the revolver's existing scope grooves or require drilling and tapping, similar to Weaver rail mounts. The stability and adjustability vary significantly depending on the manufacturer and design.
Factors to Consider When Choosing a Mount
Before purchasing a red dot mount, carefully evaluate the following:
1. Red Dot Sight Compatibility:
Ensure the mount is compatible with your chosen red dot sight's footprint (e.g., Weaver, Picatinny). Mismatched mounts and sights can lead to instability and potential damage.
2. Mounting Method:
Consider the permanence of the mounting method. Permanent modifications, like drilling and tapping, are irreversible and require professional gunsmith services. If you're not comfortable with permanent changes, opt for a top-mount adapter.
3. Material and Durability:
The mount should be constructed from high-quality, durable materials such as steel or aluminum to withstand recoil and ensure long-term reliability. Look for mounts with robust construction and precise machining.
4. Sight Height:
The height of the red dot above the bore axis significantly impacts your sight picture and point of impact. A higher mount can lead to a more comfortable shooting position but might affect accuracy at longer ranges. Experimentation and zeroing are crucial after installation.
5. Cost:
Red dot mounts range in price, with permanent modifications (including gunsmithing fees) being significantly more expensive.
Installation and Zeroing
Installing a red dot mount and sight requires precision and attention to detail. Unless you are an experienced gunsmith, it's highly recommended to seek professional help for permanent modifications like drilling and tapping.
Zeroing your red dot sight after installation is crucial for accurate shooting. Start at a close range and gradually increase the distance as you fine-tune the adjustments.
Conclusion: Enhancing Your Ruger GP100
Adding a red dot sight to your Ruger GP100 can significantly improve its versatility and accuracy. However, careful consideration of the available mounting options, compatibility, and installation process is vital. Choosing the right mount ensures a safe, stable, and accurate shooting experience. Always prioritize safety and seek professional help when needed. Remember to consult your local laws and regulations regarding firearm modifications.
