Well I think you have the defensive and offensive area covered pretty well but I'm not seeing much for plinking or hunting arms. I think you have a couple of good rifles for deer hunting, but not seeing much for varmints or small game. Just a couple of suggestions on some calibers you might look into.
.22 rifle and pistol, great for small game hunting and great plinking round
.17 hmr great small varmint round
.243 great larger varmint round
7mm08 just because I love this round, bit stiff on ammo prices though
a 410 or 20 guage a must for a proper hunting collection.
Only other gun I would suggest not a hunting gun is a 38 snub
