same things goes for whatever "new" caliber hottest gets released every 2-3 years....Dude you "need" a 300AAC, (subsonic generally its a 45 acp, and super it's a 7.62x39, congrats....)
oh...that is so last year now I "need" a to sell my 308 for a 6.5 creed....etc, because it is better, you know when I need to "reach..." past 500+ yards....
.
Get things because they are cool or useful to you, not because it's the new gun hipster trend. If your 50 lbs plus overweight, and decked out...you'll be the first to expire anyway, and I will have plenty of your equipment so snag....lol. while you ride you bmw 1250GS to protect your local starbux coffee shop from rioters...
IMO...9mm, 45 acp, 5.56, 7.62x39 and 308 have been hunting and protecting for 50+ years and will continue to be readily available. Continue to do so for another 100, probably to the heat death of the universe or zompig a pork a lipse, ...but you do you....so to speak.
A $300 gun, 300 in ammo, and a 300 training day....beats a $1000 boutique glock-i-zine, every time. But...if you absolutely need to gun hipster into something, some type of 5.7 pistol makes the most "sense", if you can get the good ammo for it.
This thread needs more gun porn....post away...
