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.

  • Walt said:

    It was easy to order and had no problems comparing products. The package was heavy but taped and secured well. It arrived in the normal amount of time and performed well at the range. Good value.

  • Gomar cools said:

    Good round and a value at the price point. Rounds ramp well in all makes of gun we use.

  • Donnie said:

    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.

  • Steiny said:

    I had been hoping for prices to drop before I ran out of my existing supply but that wasn't happening. Then I ran across ammo.com and found these. I'd never had any of this brand before but I'm quite satisfied with the product and ammo.com. All my future purchases will be through ammo.com.

  • Nikonsal said:

    Received ammo in 2 days. Shot 400 rounds first day with no issues what so ever. Have shot a total 750 rounds so far with zero problems with ammo. Great value.

  • Ed said:

    I was very surprised at the speed of delivery, received my ammo 2 days after placing the order. Went to the range week later and put 200 rounds down range. No miss fires, jambs or fly always. Great service, great ammo.

  • Razorback said:

    Shipped on time and arrived in good condition. Feeds well in my Taurus PT 101.

  • BC said:

    Happy with the ammo, shipping and communication was top notch! I wish the prices would come down, i realize this is not the retailers fault. Will continue to buy here!

  • mike said:

    I have only shot about 150 rnds through the gun, and the only hiccup was a few jammings that I believe were caused by an off brand 25 rnd. capacity clip.

  • Driggs said:

    I have been practicing with this ammunition with good results since July 2023. I have qualified on the ICE Course with the JHP version with satisfactory results.

  • scot said:

    after about 250 rounds no problems at all, will be getting some more soon.

  • Doctor said:

    See summary. Good quality overall.

  • COACHC said:

    Great ammo. No problems what so ever after firing 200 rounds. Good price and super quick ship.
