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.
