ProMag Smith & Wesson SD9/SD9VE 9MM 32-Round Magazine - SKU: SMI-A20 - UPC: 708279013393

Product Description

The ProMag SMI-A20 is an extended 32-round high-capacity magazine engineered for Smith & Wesson SD9 and SD9VE 9mm handguns. Designed to significantly expand onboard capacity for high-volume range training, dynamic shooting drills, and target practice, this magazine provides a durable, heat-treated steel feed source built to withstand sustained cycling demands.

Constructed from heat-treated carbon steel, the magazine body is finished in a protective black oxide coating to guard against corrosion, abrasion, and carbon build-up. An injection-molded polymer follower works in tandem with a heat-treated chrome silicon wire spring to ensure reliable round elevation and smooth stack transition. The unit features a removable molded polymer floorplate for easy field stripping, cleaning, and maintenance.

Engineered to lock cleanly into standard SD9 and SD9VE grip frames, the SMI-A20 delivers extended operational runtime between reloads while maintaining structural rigidity across continuous firing schedules.

*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Smith & Wesson SD9 and SD9VE 9mm pistols (Not compatible with SW9VE/Sigma series or M&P platforms).

1. Ensure the firearm is unloaded, magazine removed, and chamber verified clear prior to magazine insertion or testing.
2. Load cartridges individually, ensuring each round is pressed fully backward against the rear spine of the magazine body. (A mechanical mag loader is highly recommended due to high spring tension in extended 32-round tubes).
3. Inspect feed lips for clean, uniform alignment before initial range use.
4. Insert the loaded magazine firmly into the grip well until the magazine catch locks securely into place.
5. To clean internal tube walls, depress the baseplate lock pin, slide the polymer floorplate forward under control, and remove spring and follower for dry silicone swab cleaning.
