History of 40 Cal (S&W) Ammo

The .40 S&W cartridge was developed to provide more stopping power than the 9mm Parabellum and better handling than the .45 ACP. A team from Smith & Wesson and Winchester achieved these goals, creating a rimless, 10x22mm round with a .40-inch (10mm) bullet weighing between 105 and 200 grains (gr). This cartridge offers enough stopping power for home defense and concealed carry while being manageable for shooters of various sizes.

    I am a firm believer in Blazer Brass 40 S&W. I've never experienced a jam thru my Glock 23 with this ammo and it is a very clean shooting bullet. Plus excellent service as always from Ammo.Com. Ordered on Monday, entire order here on Tuesday!!!! Thank You

  • Ross said:

    I've used this ammo for the last few months. I've put over 1000 rounds down range and haven't had any issues. Perfect for the range.

  • 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.

    Have run over 14,000 rounds(yes...that's fourteen-thousand- plus) through my Sig P229 and I believe maybe two or three were misfires. I am very satisfied with the product.

  • Tom said:

    I am a returning customer the ammo is always great and priced below others out there shipment couldn't be easier . This is a great company to do business with

  • Joe said:

    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.
