40's 

People that hang out with one another but don't act like friends, primarily a large number of people hanging togeher but half of them aren't even associated or friends with each other. They jumble togther to look big but are pussies inside. Most of them talk shit behind each others back but don't show it. Most 40's grow increasingly fast. this occurs mostly when one person knows another person, then another person knoes another person, yet he/she does not know the other person, and the cycle continues. A person with a "40" mindset usually feels cocky since he thinks he has large support when indeed he i alone.

why are there so many 40's.

.40 S&W 

A handgun cartridge that is very popular for self-defense and is increasingly being used in police service pistols. Smith and Wesson developed the .40 S&W round off of the 10mm round in order to fill a large gap in stopping power between the 9mm and a .45 ACP. Unlike other rounds, .40 S&W bullets feature a flat tip as opposed to a smooth conical tip as seen in a 9mm. The bullets were designed this way so more surface contact will be made with the bullet's target. The .40 travels at very high velocities, giving the shooter quite a bit of recoil when the gun is fired. However, this additional velocity makes the bullet ideal for shooting through light cover such as car doors or windshields.

Data compiled from police shooting incidents put the .40 S&W at a 96% chance of stopping an attacker with one shot, proving it's value as a formidable defense cartridge. Cheaper than .45 ACP rounds, yet just as effective in getting the job done, the .40 S&W has seen great commercial success.

Guns chambered in .40 S&W are an excellent choice for self-defense.
