Contrary to what certain ignorant folks who honestly shouldn't comment on such things will mindlessly repeat until the end of time, Short Barrel =/= Poor Accuracy.
Firearms with short barrels are certainly less accurate at long range when compared directly with the exact same firearm with a longer barrel, but even then the difference in most cases is extremely marginal, hence why a direct comparison is required to even notice the difference.
Oh, and I should add that such differences in accuracy are typically best noted when comparing extremely different barrel lengths like a 1.75" snubby barrel vs a 7.5" barrel, or an 18" barrel vs a 30" barrel. Not a 14" barrel vs an 18" barrel.
I must admit that I find it amusingly ironic that certain folks constantly choose to write off short-barreled shotguns as things which are only effective in movies, yet they seem to be under the impression that the massive spread that comes out the barrel of shortguns often shown in movies is 100% accurate based on their comments in regards to the accuracy of said firearms.
Also, I love the complete absence of common sense coming from these people... Honestly, Police and the Military have been using shotguns with even shorter barrels than that of the Shockwave to great effect for decades, but apparently they're just useless gimmicks that are objectively inferior in any given situation to your typical shotgun with a stock and a measly 4" of barrel length. Oh well, I suppose the Military/LE just doesn't know any better... If only the Military/LE had the vast amount of experience shooting firearms as the average opinionated forum-goer...
No seriously, that wasn't sarcasm, I'm sure that if the Military/LE had only fired shotguns with 18"+ barrels then they too would make the hasty supposition that a shotgun with a 14" barrel is completely inaccurate/worthless. On second thought, nevermind...Only a complete buffoon would think that shortening a shotgun's barrel by a mere 4" would render it completely inaccurate.
Last but not least, I've said this before and I'll say it as many times as necessary, anyone who refers to a firearm as a toy in a derogatory sense shouldn't own a firearm, nor should they have children because they lack the proper respect and knowledge of the objective lethality of all firearms. Honestly, if that's how you feel, then you might as well go sell your firearms and put your kids up for adoption because you're clearly not mature enough to be trusted with either.
Oh but there is another option, grow up. Stop acting like an ignorant child who constantly injects his opinion on matters he doesn't understand into discussions between folks who know better. The grown ups are talking, and if you want to join in then you need to know what you're talking about. Until then, go sit in the corner and think about what you've done until approximately one minute for each year you've walked the Earth has passed, then either go get educated or go play with the other boys who call deadly weapons toys.
