First and most important is a .22 rifle which is accurate and can be reloaded from a small or large capacity mag. You might have to try several 10/22’s before you find a real accurate one. Then find a high quality high capacity mag for it. Anything over 19 rounds is OK but I would rather have 50.
Next a .22 pistol small enough to conceal but accurate enough for informal target shooting or hunting. A good choice would be a Walther PP if you find a reliable one. Some are not totally reliable but just about all of them are accurate.
Another possibility would be one of the Beretta model 70 series .22’s. they are both accurate and reliable and weigh less than the Walthers.
Next you need a real stopper for those odd times when you might have to shoot through automobiles. Something like a .338 Lapua on a Sako action.
Then a powerful accurate rifle for which ammo is available everywhere. A pre-64 Winchester 70 or one of the later ones which have the Mauser extractor and controlled round feeding..
For shotguns you need a Remington 1187 with the short barrel but still with chokes and high capacity mag.. An 870 will do nearly as well.. Also a short barreled side by side double in 12 gauge.
A Smith & Wesson model 29 with 6 inch barrel, and another model 29 with an 8 3/8 inch barrel. The old ones with blue finish and no underlug.
A SigSauer P226 and a bunch of mags. A Colt M1911 with nothing done to it except maybe better sights. Also a Browning Hi-Power preferably an older one or an Argentine one.
A Ruger .22/.22 mag with a six inch barrel. A Kimber .22 bolt action for those precision shots at short ranges. An Anschutz would do as well.
An old 10 gauge single barrel with improved cylinder when you are just mucking around and don’t want to appear suspicious.
I would also like a S&W model 19 for .38, .357, .38 Long or short Colt. I would prefer a 6 inch barrel.
And last of all, a like new 6.5 Swedish Mauser with beat up looking stock and Redfield receiver sight and front sight blade replaced with a sourdough blade.
Lots more but that is enough for now.
We’ve got a lot of guns.
The .22 five shot is a POS. Every time I’ve practiced shooting with it, my right thumb gets cut. BUT OTOH, it fits into a manicure kit. Screw the thumb.
