Frequently Asked Questions
Buy .40 S&W Ammo for Sale
Is a 40 cal stronger than 9mm?
Yes, .40 S&W generally delivers more energy than 9mm. It fires a heavier bullet, typically 180 grain versus 124 grain, producing greater muzzle energy. Recoil is noticeably stronger, which can affect accuracy. Modern 9mm ammunition has narrowed the gap considerably, leading many agencies to switch back.
What is .40 S&W good for?
.40 S&W suits defensive pistol use and law enforcement. It offers heavier bullets than 9mm with manageable recoil in compact and full-size frames. Ammunition and firearm options are widely available, making it practical for concealed carry and home defense.
Why did the FBI stop using 40 S&W?
FBI and other agencies shifted from .40 S&W to 9mm due to improved modern 9mm ammunition, faster target reacquisition, higher magazine capacity, and lower recoil. The .40 offered no clear ballistic advantage to justify its drawbacks. Cost and training efficiency also favored the return to 9mm.
Why is .40 S&W unpopular?
.40 S&W declined after law enforcement switched to 9mm, citing modern ammunition performance, faster follow-up shots, higher magazine capacity, and lower recoil. Civilian shooters followed. It now occupies a middle ground with no clear advantages over 9mm or .45 ACP, reducing its appeal and market presence.
What are the disadvantages of .40 S&W?
.40 S&W has more recoil and muzzle flip than 9mm, slowing follow-up shots. Ammunition costs more and availability varies. Modern 9mm loads offer comparable terminal performance with less shooter fatigue and reduced frame stress over time.
Who makes the best .40 pistol?
"Best" depends on your needs. The Glock 23 Gen 5 and SIG Sauer P229 rank highly for reliability and accuracy. The Springfield XD-40 also performs well. Compare features, ergonomics, and price across manufacturers to find what suits you.
What is the price range of a S&W 40?
S&W .40 caliber pistols range from around $350 to over $790 depending on model and condition. New models average around $712, with compact variants like the M&P40C available for as low as $349.99 new. Used examples average around $443. Prices vary by specific variant and retailer.
Is 40 S&W a dying caliber?
.40 S&W is widely considered effectively dead as a defensive cartridge, with guns being discontinued and prices dropping significantly since the FBI returned to 9mm.
Does a .40 kick harder than a 9mm?
Yes, .40 S&W produces noticeably more recoil than 9mm. It generates higher pressure and greater felt kick, making follow-up shots slower for most shooters. Gun weight and design also affect perceived recoil, and hot 9mm loads can approach .40 levels.
What is the most lethal .40 cal round?
"Lethality" depends on your goal. For defensive use, rounds achieving 0.6+ inches of expansion and 12-18 inches of penetration perform reliably. Black Hills 155-grain JHP, Black Hills 140-grain TAC, and Winchester 165-grain PDX1 consistently rank among top performers in terminal testing. Choose based on your specific firearm and intended application.
