I hadn't particularly thought about the need for a .22, but now that I think about it, I can think of several situations that something bigger wouldn't be necessary. (snakes?)
Practical uses aside, I must have both a .22lr rifle and a .22lr handgun (or a .22lr conversion kit for a handgun). I really enjoy shooting and try to get to the range once a week. .22lr allows me to get a good amount of quality shooting in.
1st: .22lr ammo is very inexpensive, and match-grade ammo is inexpensive relative to match-grade centerfire ammo.
2nd: .22lr has very little recoil and is relatively quiet (but you still have to wear hearing protection
).
3rd: .22lr guns tend to be very accurate, if you compare them to similiarly priced centerfire guns.
This means owning guns in .22lr makes great sense because shooting .22lr is both very accessible and very rewarding. Every gun owner I know has several .22lr guns and they shoot them regularly. So I'll cheat and pick six guns for my minimalist collection
.
.22lr rifle CZ 452 Lux in .22lr. Great little rifle that I shoot all the time.
Centerfire rifle M1 Garand in 30-06 or .308 win. In a pinch, I can use this for a variety of purposes and sometimes .22lr just 'aint enough.
Shotgun Well, I'd have to say Remington 870 in 12 gauge, but that's partly because the only shotgun I've ever fired was a Remington 870
. It's considered a classic, by the way.
Handguns 1911 in .45 ACP gussed up by a master 1911 gunsmith.
Browning HiPower in 9mm Luger.
S&W 686 in .357 magnum.
And I'd get a Marvel .22lr kit for the 1911, too! BTW, CCW is not possible where I live
.
