Frequently Asked Questions
.40 Ammo - 100 Rounds
Is .40 more expensive than 9mm?
Generally, .40 S&W ammunition costs more than 9mm, though the gap varies. For common FMJ practice ammo, .40 runs roughly 20% higher than 9mm. Marketplace data shows .40 typically around $46 per box, with listings between $30–$87. 9mm remains the more affordable option for budget-conscious shooters.
Do Walmart sell 40 caliber bullets?
Walmart sells .40 S&W ammunition both online at Walmart.com and in many physical store locations. Prices typically range from $30 to $87 per box depending on brand and quantity. Availability varies by store, so check your local Walmart or their website for current stock.
Does 40 hit harder than 9mm?
.40 S&W fires a heavier bullet at higher pressure than 9mm, delivering more muzzle energy. Modern 9mm hollow point ammunition has narrowed the performance gap considerably. Both calibers are effective for self-defense; the better choice depends on recoil tolerance, shooter accuracy, and specific ammunition used.
Which is cheaper, 40 S&W or 45 ACP?
The price relationship between .40 S&W and .45 ACP varies by market and retailer. Neither is consistently cheaper than the other. In some markets, .45 ACP actually runs cheaper than .40 S&W. Check current prices at your local retailer or our marketplace to compare before buying.
How much does a .40 caliber bullet cost?
.40 S&W ammunition typically costs $30–$87 per box of 50, averaging around $46. Prices vary by brand, bullet weight, and load type—range ammo runs cheaper, while defensive hollow-points cost more. Expect to pay roughly $0.60–$1.00 per round depending on the manufacturer.
Is 40 cal ammo hard to find?
.40 S&W availability varies. However, local availability can be inconsistent, and some shooters report difficulty finding it regionally. The caliber may be losing shelf space as its popularity declines.
Why is Glock discontinuing 40 caliber?
Glock hasn't fully discontinued .40 S&W, but has discontinued dozens of models in that caliber, listed on their official Discontinued Pistol Models page. The reduction reflects falling demand as law enforcement shifted to 9mm for lower cost, higher capacity, and better ammunition performance. The .40 S&W lineup is now significantly smaller.
Why is .40 S&W unpopular?
.40 S&W declined after the FBI and many police departments switched back to 9mm in the 2010s, citing improved 9mm ballistics, lower cost, higher capacity, and less recoil. With reduced law enforcement demand driving the market, .40 S&W ammunition became less common and more expensive.
