Warne MESIG54BLK Sig P320 Magazine Extension +5 Rounds 9mm

The Warne MESIG54BLK Magazine Extension transforms standard Sig P320 magazines into higher-capacity platforms, adding five additional 9mm rounds without compromising reliability. This precision-machined extension integrates seamlessly with factory magazines to deliver extended shooting capability when capacity matters most.

What Makes This Different

Unlike polymer alternatives that can crack under stress, this extension features 6061-T6 aluminum construction with hardcoat anodizing for superior durability. The precision manufacturing ensures consistent feeding and reliable function across thousands of rounds. Factory-spec tolerances maintain the magazine's original profile while adding substantial capacity.
