SIG SAUER P322 .22 LR 20-Round Magazine

SIG SAUER P322 .22 LR 20-Round Factory Magazine

Keep a dependable factory magazine ready for range sessions, practice, and recreational shooting with the SIG SAUER P322 20-round magazine. Made specifically for the P322 pistol, this genuine SIG SAUER accessory pairs the platform’s standard 20-round capacity with lightweight polymer construction and features intended to make loading and round checks more convenient. This is the black .22 LR version identified by manufacturer part number 8900745.

Purpose-Built for the P322

A magazine is a key part of a semiautomatic pistol’s feeding system, so correct platform compatibility matters. This magazine is designed for the SIG SAUER P322 and holds 20 rounds of .22 Long Rifle ammunition. Its factory dimensions, follower, feed geometry, and polymer baseplate are configured for the P322 rather than adapted from another pistol family. That makes it a practical choice as a spare, replacement, or additional range magazine for owners who want an OEM component.

Loading-Assist Design

SIG SAUER equips the magazine with loading-assist tabs connected to the follower. The tabs can be drawn down slightly to reduce spring pressure while a single cartridge is inserted. Loading one round at a time and keeping each cartridge properly aligned helps the rimmed .22 LR ammunition stack correctly. The assisted design is especially useful during longer practice sessions when several magazines may be loaded repeatedly.

Side witness holes provide a visual reference for the ammunition column. The magazine body and baseplate are polymer, helping keep the accessory light while maintaining the form needed for consistent fit in the P322 grip. Its black finish matches the standard appearance of the pistol and other factory accessories.

Use and Care

Before use, confirm that the pistol is a P322 and that the magazine seats and releases normally while the firearm is unloaded. Follow the P322 owner’s manual for loading, unloading, inspection, and cleaning. Avoid forcing cartridges into the magazine or pulling the loading tabs farther than needed, since careful loading supports proper rim alignment. Periodically inspect the feed lips, follower, body, and baseplate for dirt, damage, or unusual wear, particularly after the magazine is dropped during training.

Magazine-capacity rules vary by jurisdiction. Buyers are responsible for confirming that a 20-round magazine may be purchased, possessed, and used at the destination. The package contains one magazine; firearm and ammunition are not included.
