Maximum Capacity in a Compact Package

The Shield Arms DS18 magazine revolutionizes aftermarket Glock 19 magazines by delivering 18 rounds of 9mm ammunition in nearly the same footprint as factory 15-round Glock magazines. This breakthrough design gives Glock 19 owners +3 rounds of additional capacity without the bulk typically associated with extended magazines.

Whether you carry your Glock 19 for concealed carry, home defense, duty use, or competitive shooting, the DS18 provides crucial extra capacity while maintaining the compact profile that makes the Glock 19 one of the most popular handguns in the world.

Engineering Excellence: Over-Insertion Stop Technology

Shield Arms brings OEM-level over-insertion protection to aftermarket Glock magazines with the DS18's integrated over-insertion stop. 

Why the Over-Insertion Stop Matters

The over-insertion stop is a critical reliability feature that:

• Ensures proper seating depth - Prevents the magazine from being inserted too far into the magazine well
• Eliminates feeding malfunctions - Maintains correct ammunition presentation to the feed ramp
• Provides consistent lockup - Ensures the magazine catch engages properly every time
• Delivers OEM reliability - Functions with the same mechanical precision as Glock factory magazines
