Federal Personal Defense Punch 40 S&W Nickel Plated Brass JHP 165 Grain 20 Rounds
.40 S&W balances power and capacity in a standard-size pistol. It fires heavier bullets than 9mm with more energy, and it served as the duty cartridge of the FBI and many police departments for decades. At Gunners Outlet we carry .40 S&W ammunition from 120 to 205 grains, including FMJ for range practice and hollow points for defense, from brands like Federal, Winchester, Fiocchi, CCI and PMC. Order online and we ship fast from our New Hampshire warehouse. Each product lists its price per round, so comparing value is simple.
Choosing .40 S&W Ammunition
Smith & Wesson and Winchester introduced the .40 S&W in 1990 as a shorter version of the 10mm Auto. It fit into 9mm-size frames while delivering energy close to the reduced "FBI load" 10mm, and it quickly became a law enforcement standard.
165 and 180 grain loads are the most popular. The 180 grain bullet is the original subsonic weight with a softer push, while 165 grain runs faster with a snappier feel. Lighter 135 to 155 grain loads offer high velocity for defense.
For training, FMJ is the affordable choice. For carry and home defense, choose a proven JHP such as Federal HST or Speer Gold Dot. Because many agencies moved to 9mm, plenty of quality police trade-in pistols are on the market, and .40 S&W ammo remains easy to find, especially when you buy in bulk.
Getting the Most From .40 S&W
.40 S&W has a sharper recoil impulse than 9mm, so a good grip and regular practice make a big difference. Many shooters find heavier 180 grain loads feel softer than fast 155 or 165 grain loads, so it is worth trying more than one weight.
Popular .40 pistols include the Glock 22 and 23, Smith & Wesson M&P40 and Sig Sauer P229. Brass-cased .40 S&W reloads well, and buying FMJ in bulk keeps the cost per round reasonable for regular range sessions.

Frequently Asked Questions
40 s&w vs 9mm: which is better?
9mm is cheaper and easier to shoot, while .40 S&W fires heavier bullets with more energy. Modern hollow points narrowed the performance gap, which is why many agencies switched to 9mm. Choose .40 S&W if you shoot it well and want extra energy per round.
40 s&w vs 45 acp: which is better?
.40 S&W offers more capacity and higher velocity, while .45 ACP uses heavier bullets with softer recoil. Energy is similar between typical loads. Pick the one you shoot best in your chosen pistol.
40 s&w vs 10mm: which is better?
10mm is more powerful, while .40 S&W is easier to control and fits smaller pistols. The .40 is a shorter 10mm, so it carries less powder and energy. Choose .40 for carry and duty, 10mm for hunting and woods defense.
Is 40 s&w for self defense?
Yes, .40 S&W is an excellent self-defense cartridge with a long record in law enforcement. Use a quality JHP and practice enough to manage its sharper recoil.
