1. Most "recreational weapons" are derived from military weapons. 1911 was an officer's gun. Glock started for Austrian Defense. Mossberg shotguns are used by Marines. The .30-06 Hunting Rifle is a military round.
2. It's not the Bill of Needs, but the Bill of Rights.
3. Governments that do not trust me with "military weapons" are not trustworthy enough to hold power.
1911 was not an officer’s gun, it was a cavalry gun. A lesson of the Civil war was the effectiveness of large caliber pistols when used by cavalry. The .44 cap and ball revolver is as effective as ever it was. The .45 Colt, the .45 Schofield (S&W) and the 1911 were all product improvements on something that worked. Of course that cavalry stuff had to change a lot once machineguns became widely distributed.
Even in 1939, German infantry formations got very weary of being attacked by Polish Cavalry.
