Winchester Ammunition first launched its Defender line of personal defense ammunition five years ago, providing responsible citizens with the most reliable ammunition to protect their homes and families.  Winchester continues to add to the line up of innovative ammunition for personal defense with a 20 gauge segmenting slug.
The Winchester Defender Segmenting Slug combines all of the advantages of a slug and buckshot, while eliminating the need for two different rounds. This greatly simplifies the shotgun platform, allowing one round to be used for all situations. The round is designed to compensate for aim error over traditional slugs. Upon impact, the slug segments into three equal projectiles – delivering greater knock-down power than traditional buck shot loads, improving aim error and reducing the chance of stray projectiles in confined spaces.

The segmenting slug is designed to split into three pieces as it enters the target eliminating the chance of the slug passing through and striking additional objects in its path. This new offering further broadens the impressive Defender® line up that already includes most calibers in centerfire pistol, centerfire rifle, 12 gauge and 410 personal defense.

“It’s our job to create the right product for every situation whether it’s for hunting, recreational shooting sports or personal defense,” said Brett Flaugher, Winchester Ammunition vice president of sales, marketing and strategy. “The addition of the 20 gauge segmenting slug to the Defender line provides customers and responsible gun owners with more options to defend themselves when faced with life-threatening situations.”
