Shield Arms S15 Gen 3 15-Round 9mm Magazine for Glock 43X/48

Shield Arms S15 Gen 3 15-Round 9mm Magazine for Glock 43X/48

The patented Shield Arms S15 Gen 3 is a flush-fitting 15-round steel magazine for the Glock 43X and Glock 48. It is the same length as the OEM Glock 10-round magazine but holds five more rounds — a 50% capacity increase in the same footprint — thanks to Shield Arms' staggered-round geometry. Available in QPQ Nitrocarb (black), Silver Nickel, and Black Nickel finishes. Made in the USA and backed by Shield Arms' Lifetime Warranty and "Spring for Life" guarantee.
