I have a heck of a lot of guns, each time I get one out of the safe I think its the Gun of Guns. Then comes the next one.
I suppose if I really had to pick one, It would have to be my SC 1903A3.
For a hand gun, I guess it would be my old service revolver, 4in Model 28. The one I was issued and carried most of my 20 years in LE and my department gave me when I retired.
