Wow.
What a complete and total load of pure crap!
Come stand in front of it for me and I'll bet you'll change your tune.
There is a REASON why the HK MP5 for example is still popular to this day.
And it has nothing to do with full-auto either since it has single shot mode as well and is often employed that way.
Plus, you get added velocity from the longer barrel than you do with the same round from a pistol, and 30 rounds of stable firepower to go with it.
For that matter, 9mm pistols alone have been used for HD for decades as well....and you don't see people like you and your erroneous opinions complaining about that now do ya?
You've been watching too many Kung-foooey movies or something.....lol
"No offense" as you put it...but anybody who thinks PCCs suck for HD doesn't know the first thing about them first hand at all other than what you may have read on the interwebzzz from other people who don't know anything about them either.
You obviously missed my sig. I won't stand in front of a PCC , but if I have the choice between a PCC, shotgun, or rifle, the PCC is going to be a distant third. I'm not saying that PCCs won't do the job, but they don't do it any better than a rifle or shotgun, for reasons I believe I've stated earlier in this thread.
A 9mm pistol (or pistol caliber carbine) will poke a 9mm hole through the target. It's lack of velocity has two very important effects. It does have increased velocity compared with a pistol, but because those cartridges are designed for short barrels, you don't get that much in a longer barrel. Even a .357 magnum in a lever action doesn't reach nearly the speeds of a rifle round. Those two important effects I mentioned are:
1) It does not reach the velocity required to cause damage with the cavitation effect. All of the damage done with a pistol is simply the bullet crushing tissue as it passes through. With a rifle, like a .223, the damage is both from the bullet passing through, and from the tearing of tissue from the resulting shockwave. The shockwave still occurs with a pistol round, it's just that at the lower velocity the tissue doesn't stretch beyond the elastic point. Thus, you get a much bigger hole with a .223 than you will with a 9mm. This isn't just information on the interwebz, it's corroberated by real-life use and by gel reports.
2) With the lower velocity, bullet engineers cannot control how the bullet expands. With a JHP 9mm round, if it misses the target and goes through a wall, or if it hits a target with heavy clothing, it could clog up with dry material and fail to expand and function like a ball round, complete with a thinner wound channel and MORE overpenetration.
Thus, for two of the biggest considerations for HD - those being "will it stop a target?" and "will it kill my neighbor?", the advantage goes to a rifle.
The MP5 is still popular, but not nearly as popular as it once was. SWAT teams and special forces are largely phasing out the MP5 for the M4 or similar carbines. The MP5SD is a different animal. If you want stealth, you want subsonic. When you go subsonic, you want a fat, heavy bullet, because you lose all the benefit you would have had with a rifle cartridge (it is impossible to be under the speed of sound and over 2000 FPS at the same time).
A lot of what you said about the MP5 (or a civilian 30-round PCC) applies to an AR. A non-NFA PCC and rifle will have very similar features, including size, layout, capacity, and aftermarket modifications available. Granted, the PCC will be slightly smaller, and the recoil will be slightly less. But the recoil of the .223 is negligable at worst, and the small size difference is a huge tradeoff when you consider the difference in wound tract and overpenetration mentioned above.
So no, I'm not full of crap. I didn't say they sucked, they'll do the job, and they'll do it better than a pistol. But a rifle offers all the benefits, plus a lot more. If all you have is a PCC, it'll work, and it'll work well. But if you're picking a gun specifically for HD, unless you really need the smaller package, a rifle is much more suited to the task.
It's like when you're buying ketchup. Yeah, Hunts is still ketchup, but it aint Heinz.
