Well to be realistic about it, ie no full auto, militarty etc.
1st choice would be a nice Ed Brown Cobra Carry or Les Baer 1911. I would really like to own a really high end nice 1911.
2nd Choice would be a real Colt Single Action Army.
3rd Choice would be a Marlin 1894 Cowboy in .357.
Totally unrealistic....
MP5SD2 or 3.
