Well I've bought and sold a number of different firearms as I tried to find MY perfect CCW EDC. Now, 7 years into my pursuit, I think I have a very balanced stable of firearms each fitting an intended purpose. Not nearly the number that many of you have I'm sure, but all of mine fit all of my stated needs:
Ruger LCR .357 Magnum - EDC (pocket or IWB in Remora - I live in FL)
Glock 19 - secondary carry piece and night stand gun
Mossberg Mariner 590 12 Ga - primary home defense gun
Saiga AK-47 - everyone needs at least one high powered rifle chambered in a widely available caliber
Marlin Model 60 - fun to plink with, cheap and plentiful ammo, effective as a survival gun if ever needed (small game, etc.).
Have you planned your collection or just end up with it?
