40 S&W

The 40 S&W (aka ".40 cal") was developed after the FBI deemed the 10mm’s recoil to be a little too snappy for some of its … let’s say “more delicate” agents. This cartridge is especially popular for self-defense (See our top defensive ammo picks for 40 S&W here). 40 SW Bullet weights ranging from 105 to 200 grains are available, although many agree that 165 or 180 grains is optimal for personal protection. We work to keep bulk and defensive options ready for sale. You'll see our in-stock options below.

    In my opinion, the Winchester Ranger T series is the best EDC ammo out there in .40 S&W. It's extremely hard to find as well. I had been searching for it for quite some time and the only place I found it was at Ammo To Go.

    I understand people at first saying that this round was a gimmick. I even waited for two iterations of this round before giving it a good go. With this being the third generation of the RIP projectile, I can definitely say that they got it right. They serrated the trocars so that they would penetrate deeper which was an absolute pro move. They also added weight to them, and now the trocar penetrate deeper in ballistics gel and view any x-ray of an RIP bullet victim and you will see I just how deep the trocars now penetrate and spread. I was once a skeptic, and I certainly believe the first generation had its issues. But now I am an absolute believer, and would not trust any other round for within my home, where I need around to dump all of its energy into the intended target and not leave any projectile outside of them.
