We all want our guns to shoot far and to fire fast, but how much performance do we actually need? Makers of Oodammo pistols boast that they shoot 60 - 70 feet, but there is no way that you can reliably hit a moving target with a knex gun at that range with any weapon, especially pistols.
A good weapon should be able to fire fast, and be accurate to say 30 feet. This would allow the said gun to hit targets ar range reliably.
Think about it.
