I have many employees, some of whom are enthusiasts like myself. Recent conversations with some of them prompted this post.
I hear so often that people want to buy this caliber or that caliber, to "add" to their arsenal.
I disagree.
My philosophy is different. I suggest to them, that accumulating calibers is not the ideal thing, but instead the accumulation of ammo is the thing to do. In other words, I'd rather have multiple 45s with a massive bulk of ammos, rather than multiple caliber weapons with few or no stockpile of ammo.
The point is, ammo is the key, not the number of calibers one might possess.
I see it a bit different, as I use different tools for different jobs. The majority of the time my carry weapon is one of my .40s but I have 9mm, .45, .357,.22 in hand guns that I like to walk outside to the range and shoot. For hunting I keep a varied selection for where and what I am hunting. Then I have ARs for varmints and the range then my fav SKS so I end up with an assortment. Usually when I go out to my range I end up with 5-7 different calibers because I can't choose one
Perhaps the definition of "multiple" wasn't agreed upon. I agree with your post. I guess my point was more toward the dude who has to have a 9mm, a .45acp, a .357, a .40, a .44, etc...
I agree with you. I have multiple calibers, but only 1-2 per application. Example: pistol= .45 and a conceal carry LCP (.380), and everyone should have a revolver, mine, a S&W .357 (requiring the accumulation of two different calibers). Rifle= 5.56 (a few, for the fam), and a 30 cal. Two shotguns, one tactical, one for hunting. Then my 7.62x39 Zastava, which is.....well, anyone who knows already knows. My point is/was, why would I want more pistol calibers? Why would I want another revolver caliber? Why does a person want more than a good .30 caliber and an AR rifle? Look, I know there is the "collection" motive and the "hoard" motive and the enticing appeal of the "must have" addiction....I get it in spades!!

But in terms of need vs. wise preparedness, I suggest that the accumulation of ammo over calibers is the key to economic and strategic accumulation.
The genesis of this thread was a conversation I had with an employee who insisted I must get a Glock 19, a 9mm pistol. I had to ask myself, why? If I was a collector for collection sake, then perhaps....otherwise, I'd rather just buy more ammo for what I got.
But, to each their own.... $$ and space being a big factor, of course!
