Hmmm, For an effective quick fill to satisfy my very most basic firearm needs? Tough to do, because I am so damn fussy, few new bought guns would do it...so if I wasn't looking to replace the exact firearm, but just useable most frequently used guns that I consider indispensable:
Handgun....Ruger Blackhawk 5" bbl .357, Smith and Wesson model 36 .38 snubbie.: Carry, packing, home defence.
Older manufacture Marlin model 39 .22, plinking, small game, but a stainless synthetic stocked Marlin model 60 would do.
Ithaca model 37 with variable choke raised rib 12 gauge, interchangeable slug bbl small game, wildfowl, potential deer, but I haven't really actively hunted with a shotgun in decades.
Thompson Center inline with 4 x leupold scope, deer, but there are many decent inlines to pick from nowadays.
Winchester Classic model 70 featherweight in .308 main go to deer rifle. This is only a "settle for" as I could never replace my 8o year old 8mm Oberndorf Mauser that I have built up over thirty years or my Browning falling block 45-70.
