The Sig Sauer P320 has rapidly become a favorite among both law enforcement and civilian shooters, and its adaptability is a key reason why. One of the most significant advancements is the integration of optics-ready models, allowing for the addition of red dot sights (RDS) for enhanced accuracy and speed. This guide delves into everything you need to know about the Sig P320 with an optic, from choosing the right model and optic to mounting and maintenance.
Choosing Your Sig P320 Optic-Ready Model
Several P320 models are designed to accommodate optics. Understanding the differences is crucial for finding the perfect fit.
Key Considerations When Choosing a P320 Optic-Ready Model:
-
Size and Caliber: The P320 platform is available in various sizes (compact, full-size, carry) and calibers (.357 SIG, 9mm, .40 S&W, .45 ACP, 10mm). Consider your intended use – concealed carry demands a smaller, lighter model, while range shooting or home defense might favor a full-size variant.
-
Slide Configuration: Optic-ready slides typically feature a milled cut on the top to accommodate the optic's footprint. Ensure the slide is compatible with your chosen red dot sight.
-
Features: Some models include features like enhanced triggers, night sights, or upgraded barrels. Evaluate which features are essential for your needs and budget.
-
Budget: Prices vary significantly based on features and model. Set a realistic budget before starting your search.
Examples of Popular Optic-Ready P320 Models:
Model | Size | Caliber Options | Notable Features |
---|---|---|---|
P320 M17/M18 | Full-Size/Carry | 9mm | Mil-Spec, proven reliability |
P320 X-Carry | Carry | 9mm, .40 S&W, .45 ACP | Enhanced ergonomics, lightweight |
P320 X-Five Legion | Full-Size | 9mm | Premium features, upgraded trigger |
Selecting the Right Red Dot Sight (RDS) for Your Sig P320
The red dot sight market offers a wide array of choices, each with its own pros and cons. The best RDS for you depends on individual preferences and shooting style.
Factors to Consider When Choosing an RDS:
-
Footprint: Ensure the optic's footprint (the dimensions of its mounting plate) is compatible with your P320's slide cut. Popular footprints include Trijicon RMR, Leupold DeltaPoint Pro, and Holosun.
-
Battery Life: Longer battery life is crucial, especially for self-defense situations.
-
Durability: Choose an optic built to withstand recoil and harsh conditions.
-
Features: Consider features like night vision compatibility, different reticle options, and shake-awake technology.
-
Budget: Prices for RDS can range widely, from budget-friendly options to high-end models.
Popular RDS Options for the Sig P320:
-
Trijicon RMR: Known for its ruggedness and clear sight picture.
-
Leupold DeltaPoint Pro: Offers excellent durability and a crisp reticle.
-
Holosun 507K/508T: Popular choices for their value and long battery life. The 507K is a smaller footprint.
Mounting Your Optic: A Step-by-Step Guide
Once you've chosen your optic and P320 model, proper mounting is critical for optimal performance and safety. Incorrect mounting can lead to zeroing issues or even damage to the gun or optic.
Always follow the manufacturer's instructions for both the optic and the firearm.
General Steps:
-
Gather Tools: You'll need the correct mounting screws and possibly a torque wrench to avoid over-tightening.
-
Prepare the Optic: Some optics require activation or specific settings before mounting. Refer to the optic's manual.
-
Secure the Optic: Carefully align the optic with the slide cut and secure it using the provided mounting hardware.
-
Check for Alignment: Ensure the optic is properly seated and there is no wobble.
Zeroing Your Sig P320 with Optic
Zeroing your optic is crucial for accuracy. This process involves adjusting the optic's windage and elevation adjustments to ensure your point of aim matches your point of impact.
Zeroing Process:
-
Choose a Range: A range with clear sightlines is essential.
-
Start at a Close Distance: Begin zeroing at a close distance (25 yards), making adjustments as needed.
-
Gradually Increase Distance: Once zeroed at a close distance, gradually increase the distance to fine-tune your zero.
Maintenance and Cleaning
Regular cleaning and maintenance are crucial for the longevity and reliable performance of both your firearm and optic.
Cleaning and Lubrication:
-
Clean after each use: Remove any debris or residue from both the firearm and the optic.
-
Lubricate moving parts: Use a high-quality firearm lubricant on moving parts.
-
Store Properly: Store your firearm and optic in a safe, dry place.
