Polymer80 steel-lined 10-round magazine for Glock 17 pistols. A reliable, affordable alternative to OEM Glock magazines, with a reinforced steel insert for consistent feeding and durability.

Specifications

• Capacity: 10 rounds
• Caliber: 9mm Luger
• Body: Polymer with steel liner for structural rigidity
• Baseplate: Polymer, flush fit
• Compatibility: Glock 17 — all generations (Gen 1 through Gen 5)
• Also fits Glock 34, Glock 45, and other double-stack 9mm Glock models that accept full-size magazines (verify fitment for your specific model)

The steel lining prevents flex under spring tension and keeps the magazine body in proper geometry over thousands of cycles. The feed lips are reinforced against spreading, a common failure point on all-polymer magazine designs.

10-round capacity: this magazine meets the 10-round limit enforced in CA, CO, CT, DC, HI, IL, MA, MD, NJ, NM, NY, RI, VA, VT and WA, so it ships to every state we serve. Buyers in capacity-restricted jurisdictions should still confirm their local rules before ordering.
