If money was no object, which gun ???

[Zomboid]

If money was no object id have one designed and built as a one off, the only question then is which manufacturer to choose!

This all the way. I'm a springer man all the way but most of what I would like is available somewhere but if money wasn't an issue...

Single Stroke Pneumatic with different calibre options. Multi-power facility.

It would be made from the lightest of materials and expensive robust alloys. Perhaps even high grade aircraft ceramics.
