In no particular order:
If a good deal comes along, another M1 carbine. I love these guns and AR's just don't do much for me.
Another 9mm. Preferably a Browning hi power to go with my Charles Daly clone.
My first 1911. Not sure exactly which one, but either a CCO pattern or a Government. Maybe a Ruger.
For accessories, more reloading components, Tech Sights for the .22 I got for my son and a set for my 10/22. Also a micro dot to use with the tech sights on the 10/22.
Knives. More knives.
