#2 – M1911 Pistol
Perhaps the most popular pistol of the 20th Century, the M1911 has been in production for decades, having been built by several different manufacturers in the course of its illustrious history. It is still considered the weapon of choice by firearm lovers all over the world since it was developed by John Browning in the 1890s to provide the US armed forces with a semi-automatic (i.e. self loading) weapon to replace the existing revolvers.
