What .40 S&W Ammo Types Are Available?

How Much Does .40 S&W Ammo Cost Per Round in 2026?

The .40 S&W was developed in 1990 as a compromise between 9mm and .45 ACP for law enforcement, and its pricing reflects an interesting market position: it's often cheaper than you'd expect because declining demand has created buyer-favorable conditions.

FMJ range ammo runs $0.24—0.36 per round — slightly more than 9mm but often less than .45 ACP. The standard range load is 180gr FMJ, though 165gr options exist. Blazer Brass and Federal American Eagle are the most common training options.

JHP defense loads run $0.55—1.00 per round, comparable to 9mm and .45 ACP defensive ammo. Federal HST and Speer Gold Dot in .40 S&W have extensive law enforcement track records — the .40 S&W was the dominant LE duty caliber from the mid-1990s through the mid-2010s.

The .40 S&W market shift: Since the FBI's 2014 decision to return to 9mm, most law enforcement agencies have followed suit. This has created an unusual buyer's market for .40 S&W: used duty pistols (Glock 22, Glock 23, S&W M&P 40) are available at significant discounts, and ammunition manufacturers occasionally run promotions to move .40 S&W inventory. For budget-conscious shooters willing to accept sharper recoil and lower capacity, the .40 S&W platform offers genuine value.

.40 S&W Market Trends

The .40 S&W is in a slow, structural decline. New gun sales in the caliber decrease each year as 9mm dominates. However, the caliber is far from dead — millions of .40 S&W pistols are in circulation, and all major manufacturers continue full product lines. Pricing has actually improved for buyers as production capacity exceeds demand.

Frequently asked questions

What is the current price of .40 S&W ammo per round?
As of August 2026, .40 S&W ammo ranges from $0.165/rd (lowest observed) to $2.50/rd, with a median of $0.590/rd across 21 tracked retailers and 557+ listings. A quarter of observed listings price at or below $0.396/rd. IronScout updates these prices daily from in-stock online listings.
Is .40 S&W being discontinued?
No. .40 S&W is declining in popularity as law enforcement agencies switch to 9mm, but all major manufacturers continue full product lines. Millions of .40 S&W pistols are in circulation, ensuring continued ammunition production. The declining demand has actually created a buyers market with competitive pricing and readily available used duty pistols.
.40 S&W vs 9mm — which is better?
9mm offers lower recoil, higher capacity, cheaper ammo, and — with modern JHP designs — comparable terminal performance. The FBI returned to 9mm in 2014 specifically because advances in bullet technology closed the terminal performance gap. .40 S&W delivers more energy per round but at the cost of capacity, recoil, and ammunition cost. For new purchases, 9mm is the most common choice.
