Overview 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.

Customer Reviews

  • Tyler said:

    Works well enough, only had a few malfunctions in 1000 rounds shot. My big gripe is that the jackets separate from the lead core as the bullet leaves your muzzle. This does seem to be widespread on the forums that I have read. Blazer has even responded via email and acknowledged that this does happen, something related to cost savings in the manufacture process to ensure cheaper prices for the end consumer. They say there is no risk of damage to your firearm, and I have no reason not to believe that. but there is a risk if you are using Blazer ammo in live-fire training exercises, where other students might be within close proximity. some instructors have even banned the use of Blazer ammo in their training classes. So basically it is a great cheap range ammo, if you don't mind the occasional speckling of copper bits on your targets. just don't use it for live fire training exercises where you are within close proximity to other people.

    Did not have any problems with Blazer Brass ammo. The ammo's quality is good. First time I have tried them and I am pleased I tried them. Would not hesitate to purchase again..

  • Bud said:

    Greta product! A little expensive per shell, but when shells can't be purchased locally, I suppose the additional is expected. Still can't find all caliber ammo, even at ammo.com.

  • Otis said:

    value, quality and performance was as well as expected for the costs.

  • Jody said:

    I would recommend this ammo to anyone having a .40 S & W pistol..I used in my new Taurus TU pistol

  • scot said:

    ive put 1000 rounds thru my gun, I have yet to have any jams or misfires. if you want a good cheap round for target practice, this is the round for you.
