We grab longguns when we know were getting into a fight. Longguns have more range and much more fightstopping capability. Pistol caliber carbines are just pistols with a tad more range, a trifle more power and more shootability over a standard handgun. They are a poor choice compared to a 223 carbine or even when compared to a good 12 gauge.
I can always count on seeing a post from you in a Storm thread 355Sig
The Beretta Storm is SOOOO much more FUN (yes, I said FUN... some people actually BUY firearms for FUN) than my AR15s that it's uncanny. My son has tried SEVERAL times to lay claim to my Storm, and my wife recently fired my Beretta and also fell in love IMMEDIATELY.
TO ME PERSONALLY, I consider my CX4 Storm to be my ".22lr". It's not much louder than a .22, and the range is probably less, so I can shoot it in my father-in-law's 13 acre back yard without any complaints from the folks inside. They say they can't even hear it, and I'm only 50 yards from the house! But better than the .22lr, I get a bit of recoil and blast, so I don't feel like I'm shooting a pellet rifle.
Bottom line, if you will be FIGHTING A WAR or DEFENDING from ZOMBIES, then this is NOT the carbine for you... But if you JUST want to have FUN, then this thing is QUITE POSSIBLY the ticket! Also, if you're getting it for fun, BY ALL MEANS get the 9mm!
Oh, and one more response to the next comment that hasn't been made yet... YES, I can buy a cheaper 9mm carbine to have FUN, but I like the Storm better than the Kel-Tec or the other one who's name escapes me right now... (the ugly one with the hump)
