Overview

Underwood Ammo Xtreme Defender 9mm Luger +P+ ammunition features a 90-grain solid monolithic copper bullet. Designed for defensive applications, the bullet uses an optimized nose flute to create a permanent wound cavity (PWC) while maintaining penetration up to 18 inches. The solid copper construction allows the bullet to retain its structure and performance when passing through barriers such as wallboard, automotive glass, and sheet metal. These rounds are housed in nickel-plated brass cases, which provide enhanced corrosion resistance and improved feeding. Each box contains 20 rounds.

About DealsGunsAmmo (DGA)

A price and stock aggregator built for a market the incumbents stopped improving.

We compare listings across dozens of retailers and normalize everything to true cost-per-round — not sticker price, not case-size guesswork.

Who we are

DealsGunsAmmo (DGA) is an independent data provider tracking price and stock across the ammo, firearm, and parts market — giving buyers and the industry an outside, macro-level view of where the market actually stands.

What we’re building

A data-driven platform meant to be the go-to spot for purchasing decisions — comparing offers across vendors and tracking price history, so you can read the market as a whole, not just one listing at a time.

Who we serveNOW

Today, we help buyers on their purchasing journey with price alerts and a real look at where prices have actually been.

LaterNEXT

Down the road, we plan to sell that same market data back to vendors — inventory demand, customer interest and sentiment, and competitive pricing.
