About 5.7X28MM Self Defense Ammo

5.7x28mm Self Defense loads use specialized hollow point or polymer-tipped projectiles, typically in the 27–40 grain range, designed for controlled expansion and reliable performance at the cartridge’s high velocities. These loads are intended for concealed carry and home defense use in pistols and carbines where low recoil, high capacity, and flat trajectory are advantages. Pricing typically exceeds practice ammo due to premium projectile design and limited defensive load options in this caliber. The products listed above span established defensive offerings, so daily price movement reflects the broader niche market.

This page tracks live market pricing for 5.7x28mm Self Defense — premium expanding loads designed for defensive use — aggregated daily from 2000+ retailers. The chart shows the median cost per round, the market spread between typical low and high listings, and AmmoSquared's current price. Use it to see where 5.7 defensive prices sit today and time your buying accordingly.

Frequently Asked Questions

What types of ammo are available from AmmoSquared?

▾
We only stock high-quality, factory-new (not reloaded) ammunition from brands we trust, like PMC, Fiocchi, Federal, Remington, Winchester, Speer, Magtech, Wolf, Aguila, and others. When ammo is shipped, it will include a balanced variety of brands and loadings. All ammunition will be brass-cased, with very few exceptions .

Why does AmmoSquared calculate the median price and not the average?

▾
AmmoSquared gathers prices from thousands of ammo retailers and calculates the median price (rather than the average) to avoid distortion from unusually high or low prices. This method ensures transparent and fair pricing.

Why is AmmoSquared's price sometimes higher than what I see on ammo price comparison sites?

▾
AmmoSquared isn't built to always match the single lowest advertised price online. Price comparison sites often include loss leaders, temporary sale prices, limited-quantity promos, and “low price + high shipping” listings that aren't representative of what most people actually pay, especially once you factor in shipping. AmmoSquared aims for competitive, stable, sustainable pricing across the broader market. Once you factor in the benefits of getting your ammo from AmmoSquared (e.g. buy ammo automatically on your schedule and budget, store it in our climate-controlled facilities for free, available free shipping, etc.), you're getting a lot of value for the price you pay.

I found a price lower than the “Low” shown on your chart. Is your data wrong?

▾
Our price chart is based on real daily retail transactions across thousands of retailers. In other words, it's built from what people actually paid, not just what a retailer listed online. Our price chart is meant to be a helpful market snapshot, but that doesn't mean you'll never find a one-off deal below the “low.”

But I really think your data might be wrong...

▾
We do want to know about meaningful discrepancies. If you find a regular price online that looks truly comparable and lower, email us with the link (and ideally a screenshot of the price plus shipping). We review these to make sure our pricing is fair and that our data processing is accurate.
