IWI MASADA 17 Round 9MM Magazine - Black - SKU: MAS917 - UPC: 818004020524

Product Description

The IWI USA MAS917 is a genuine factory original 17-round 9mm magazine engineered specifically for the full-size IWI Masada striker-fired polymer pistol. Precision-stamped from high-strength, heat-treated steel, this magazine delivers flawless feeding performance, robust structural integrity, and long-term durability for duty, home defense, and range applications.

Featuring a corrosion-resistant black finish, the MAS917 magazine utilizes a smooth-gliding, anti-tilt follower paired with a high-tensile wire spring to guarantee reliable cartridge presentation and positive last-round slide lockup. The flush-fit impact-resistant polymer basepad cushions the magazine body during tactical mag drops while matching the contour of the Masada frame.

Equipped with numbered witness inspection holes along the rear spine, the IWI MAS917 allows shooters to quickly verify round count at a glance during staging and tactical reloads.

*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for full-size IWI Masada 9mm pistols. (Not compatible with Masada Slim models).

1. Verify host firearm is completely clear, magazine removed, and chamber visually and physically confirmed empty.
2. Load 9mm Luger cartridges manually or using a speed loader, ensuring each rim seats fully against the rear spine wall.
3. Insert loaded magazine firmly into the magwell until the magazine catch locks in place with an audible click.
4. To clean internal components, depress the baseplate locking button, slide the floorplate forward, and remove spring and follower for maintenance.
5. Do not over-lubricate the inside of the magazine body; wipe clean with a dry cloth to prevent dust and unburned powder accumulation.
