Why Upgrade Your P320 Magazine Release?

The stock mag release on the Sig P320 is reliable, but aftermarket or OEM upgrades give you an edge in comfort, speed, and customization. A modular or extended release makes reloads faster under pressure, while a nickel-finished OEM option enhances both look and durability.

For shooters who demand precision, a properly tuned mag release can significantly improve handling. Whether for home defense, range use, or professional duty, an upgraded release is a simple yet impactful enhancement.

FAQs

Q: Will these fit all Sig P320 models?

Q: What’s the difference between the Strike Industries MMR and the OEM AXG release?
A: The MMR is modular and adjustable, allowing different button profiles, while the OEM AXG release is factory nickel-plated and fixed for the AXG frame.

Q: Are these ambidextrous?
A: Yes. Both the Strike Industries and factory Sig Sauer releases can be configured for left or right-handed operation.

Q: Can I install the magazine release myself?
A: Absolutely. These are drop-in parts that require only basic tools. Follow Sig Sauer’s instructions or consult a gunsmith if unsure.

Q: What’s the benefit of a nickel finish?
A: Nickel provides corrosion resistance and a smooth, premium feel while complementing other AXG components.
