History of .40 Cal (S&W) Ammunition

Smith & Wesson and Winchester introduced the .40 S&W in 1990 to replace the 10mm cartridge which had been used for a short time by the Federal Bureau of Investigation. The 10mm had proven to be too difficult for many agents to control when firing due to the combination of harsh recoil and large grip size. In response, the FBI searched for a cartridge with less recoil that fit in existing 9mm frames and could deliver the amount of penetration required by the FBI.  The .40 S&W met these requirements, was adopted by the FBI, and enthusiastically embraced by the law enforcement community. Civilians soon followed and offered their own endorsement of the caliber.

A strong feature of this ammunition is that it is a "middle ground cartridge," yet it avoids being a compromise. The .40 S&W has more muzzle energy and down range energy than a 9mm, although the same sized pistol in 9mm will be able to hold more rounds since the 9mm cartridge is smaller. A pistol chambered in .40 can hold more rounds than it could of .45 ACP, but the muzzle energy of the .45 is considerably higher than that of a .40. The .40 strikes the right balance between muzzle energies and magazine capacity, and has been approved by exhaustive testing on the part of the FBI and many other agencies. The result has been wide-spread adoption of the .40 among the police community.  It is also worth noting that the .40 S&W has been adopted by the US Coast Guard as its primary issue sidearm.

The .40 is popular with civilians for many reasons. A wide variety of options exists for bullet weight and bullet design, and if a manufacturer produces a new line of self-defense firearms, they are sure to offer it in .40 caliber. Civilians appreciate the same benefits of the caliber that made it so popular with law enforcement: magazine capacity, muzzle energy and limited recoil. The cartridge is popular for home defense and concealed carry, as seen in the number of pistols chambered in .40 S&W of compact and sub-compact size. Defensive ammunition in .40 S&W is offered by several manufacturers including FederalHornady, and Magtech, just to name a few.

  • knox86 said:

    "I got 500 rounds about 6 months ago and so far haven't had a single jam or malfunction at the range out of my XDm. could be a little cleaner but i've worse out of new non reman ammo so not much to complain about there. I would shoot this over any blazer/tula any day. "

  • emt59 said:

    "You came through with ammo on hand when I was having trouble finding it. The ammo was competitively priced along all others."

  • SteveGun357 said:

    "Only one had a damged jacket. I didnt even load it in the magazine. The other 999 have fired perfectly. That is a 99.9% excellence record with me. Good deal. Could not believe how quickly you shipped."

  • MP 272 said:

    "Ordered the 1000 rounds - haven't shot any yet. It is clean and well made - great service! I have confidence enough to use it as personal carry! Thanks AmmoNet Dave - Sarasota"

  • gasman said:

    "A little concerned about reloads, however my concerns soon vanished as the ammo performed flawlessly."

  • Vorbdad said:

    "Even though this ammo was reloads, we experienced maybe only two jams out of 500 or so rounds shot so far. My brother and I are very happy with our results. Will definitely buy some more. "

  • Steve said:

    "I was impressed with the service from as well as the timeframe of delivery. The 40 cal MBI FMJ 180 gr. ammo looked good, fired flawlessly, and appears to be fairly clean doing it. I've only fired approximately 30 rds. through my Glock 23 gen 4 so far, but am satisfied with no jamming or ejection problems...would definitely consider in the future. "

  • kwaddell said:

    "I needed decent target range rounds for my Glock 22. Even though these are reloads not a single round jammed. All of the rounds fired cleanly. We must have gone through 100 - 200 rounds at the range. Good price. Good rounds. Will definitely purchase again."

  • Scott said:

    "Bought 500 rounds and have gone through approx. 200 and haven't had any issues. The one thing that bothered me slightly was 1 out of every 20 or so rounds was steel cased. It's not enough for me to knock it down a point in the review but it was advertised as "Brass" and it wasn't all brass."

  • Jas said:

    "Fired all 100 the first time out with 100% success. I didn't notice any difference from shot to shot like in some reloads. Every ejection was smooth and never had a hangup which is most important."

  • Top Shot said:

    "I went to the range and pumped 100 rounds out and no problems at all. Great value..."

  • The Man said:

    "pumped 400 rounds through my hand gun with no problems. It was a good deal."

  • The Patriot said:

    "Used 200 rounds at the range without any problems, Great value."

  • The Big Man said:

    "Great value for everyday range shooting. No problems what so ever with every single round."

  • Mike said:

    "Top shelf ammo for the price. 125 rounds without a hiccup. Might want to consider a lighter round in a compact...kicked too much for my wife in my sr40c (usp handled it like a champ) but I wouldn't hesitate to buy again. Maybe 165gr so we can both use it :)"

  • Donnie said:

    "Went thru 250 rounds over the last 2 weeks with no issues at all. Great ammo and very good price. Gun was a lot cleaner than I anticipated after I shot 130 rounds. Would recommend this ammo to anyone."

  • Lou said:

    "Good ammo for the price"

  • Davedee said:

    "I use CCI as my preferred ammo. Have a fussy SIG 22 semi-auto that can only use CCI products. I have no issues with CCI in my other 40 and 9 mm cal. weapons and recommend to others. Also, I share with others when I purchase in bulk so they have an opportunity to try you out. "

    "What a mess, jams, powder build up.... this ammo did everything it could to foul my weapon. I blew threw cheaper Russian AMMO in my Ruger SR40C no issues, cleaning was average. As I closed in on 80 rounds of this Remington ammo you could tell it was going to be a long afternoon, powder all over the muzzle, then the jams started and cleaning took forever! Would not recommend. "

    " Looking for some .40 cal you can feed your pistol with total confidence? Fill your magazines with the HST JHP from Federal! My Sig and I spent an afternoon punching holes with these, along with three other brands. We know there are some brands okay for range practice, because a misfeed or misfire doesn't matter much. But it was clear from the outset that if you carry, these are the guys you want to take with you. Never a misfeed or misfire, and accurate to a gnat's eyelash. I figure if it's my life and perhaps the lives of my loved ones on the line, I'll have enough to worry about without fighting the bad guys and my ammo problems at the same time. "

In a direct comparison, this is the lowest price for exactly the same ammo. The ammo came well packaged in 50-round sets and fired flawlessly. Hard to complain about that."

    "I purchased 300 rounds of this ammo to break in my Kahr mk40, I put 80 rounds thru it fresh out of the box and never fired, even though this ammo was reloads w/ mixed brass I had no problems what so ever, no stove pipes, FTF or FTE and accuracy was good as long as I did my part. Would purchase again."
