    Sig Sauer P322 22LR 4" OR Non-Threaded Barrel Accessory Compatibility & Recommendation Guide

    Product Compatibility Overview

    The Sig Sauer P322 22LR 4" OR Non-Threaded Barrel is a modern, full-size semi-automatic pistol chambered in .22 LR. Designed for versatility, it features a polymer frame, ambidextrous controls, and an optic-ready slide. Key compatibility points include:

    • Optic-Ready Slide: Accepts micro red dot sights with the appropriate mounting footprint (typically Shield RMSc or similar).
    • Accessory Rail: Standard Picatinny rail under the barrel for lights and lasers.
    • Non-Threaded Barrel: Limits direct suppressor use but does not affect most other accessories.
    • Magazine Compatibility: Uses proprietary 10-round P322 magazines.

    Essential Accessories

    Must-Have Accessories

    • Spare Magazines: Essential for training and range use. SIG Sauer OEM P322 magazines ensure reliability.
    • Magazine Loader: The .22 LR can be tedious to load; a loader like the Maglula UpLULA (universal) saves time and effort.
