Thank you.
We now return you to your irregular dose of gun porn:
The worlds oldest revolver.
Built in 1597 by a weapon produser named Hans Stopler in Nüremberg Germany. The firing mechanism is a type of flintlock and the cylinder holds up to 8 shots. The words "ahead of its time" are thrown around a lot but in this case it is true. For over two CENTURIES afterwards the revolving cylinder with one barrel was not seen again and weapons that could be fired more than once simply had several barrels. (the fact that this gun has only one barrel increases accuracy since in a multibarreled gun the barrels might by
teeny tiny bit bent in different directions meaning that they are not hitting the same spot. This is even true in my modern shotgun.)
Mace gun at the Tower of London:
Much like the axe-gun posted before this is not exceptionally functional gun but it offers a single shot (even if inaccurate and hard to aim) and can then be used to bash your enemies' skulls.
.22lr gatling gun:
If I was allowed to pick one gun to own, just for fun, just as something to take to the range and shoot at targets for pure fun... This would be it.
