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.

Shot ammo in a Glock 27 Gen 4 with very little problem. Ammo jammed a couple of times, but I don't think the ammo was the problem. I will buy more Prvi Partizan ( PPU) ammo when possible in .40 cal, 9mm, and 357 sig. Great stuff. Shoots cleaner than most other I have found.

Excellent value in a monolithic projectile hollow-point format. Without detailed ballistic testing, I would say SB being a reputable manufacturer I have a long positive history with in my handguns, I expect these in .40 to perform quite well. Well packed, excellent quality components, shipped fast at a very competitive price!

Paperbanger said:
Looking for some .40 cal you can feed your pistol with total confidence? Fill your magazines with the HST JHP from Federal! My Sig and I spent an afternoon punching holes with these, along with three other brands. We know there are some brands okay for range practice, because a misfeed or misfire doesn't matter much. But it was clear from the outset that if you carry, these are the guys you want to take with you. Never a misfeed or misfire, and accurate to a gnat's eyelash. I figure if it's my life and perhaps the lives of my loved ones on the line, I'll have enough to worry about without fighting the bad guys and my ammo problems at the same time.

Bullet Points: 40 Cal Ammo

A leading cartridge among the FBI and law enforcement agencies in the United States, the .40 Smith & Wesson gives police the capacity of the 9mm and the power of the .45 – also making it popular among civilians for self-defense and sport shooting.
.40 S&W ammo has also been adopted by the U.S. Coast Guard as its primary issue sidearm, due to its balance of muzzle energies and magazine capacity.
Civilians have adopted .40 S&W ammunition for many of the same reasons law enforcement has. Its mix of magazine capacity, muzzle energy and limited recoil make it ideal for home defense and concealed carry. Find .40 S&W ammo for sale in a variety of quantities and bullet types.
