The reason it is still used is because it packs a bigger punch than most modern handguns. The common military pistol the M9 fhas a 15 round magazine. Thats great but the bullet it fires is a 9mm bullet. The M1911 fires 8 .45 bullets which are larger than 10mm. The M1911 may be old and has less ammo capacity, but sometimes, being able to kill your target before he kills you is nice.
