40 Cal (S&W) Ammo For Sale
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

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.

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 :)

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.

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.
