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.

Capt. Miller said:
We use these to qualify our department so we go through hundreds of rounds. This stuff barely dirty's the gun and has not misfired or jammed yet.
-
Gene said:
When you pull the trigger the ammo goes "bang!" What more can you ask? It burns clear, leaving gun fairly free of residues and carbon.

Charles said:
I'm happy with the prices and delivery times; My only complaint is i would rather the products come in unmarked boxes, since I am in the process of stockpiling ammo against the future laws of our state., I would rather no one knows what I'm purchasing, and having delivered.

Prompt service on my order and the ammo performed as expected. Great savings buy from ammo.com as opposed to retail.

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.

Alan said:
I've ordered this ammo twice now. 1000 rounds each time. First 1000 went through my glock 23 without any failures of any kind. I'm onto the second 1000 now and anticipate the same flawless performance. Service is excellent. Shipping was very fast. Value is great.
