How are your points even relevant? Lighter than most rifles - so what? virtually zero felt recoil - so what? Less real world penetration of building materials - so what? What are you comparing it to?
The fact that no matter how you want to spin it, it's still just a large, heavy and bulky semi-auto in a handgun caliber. Kindly point out the benefits to we amateurs.
Wow, somebody wants to argue.
My pointes were relevant to your dismissal that they are nothing but a "large, heavy and bulky semi-auto handgun." That is simply not the case.
Compared to most rifles and carbines they are lighter. To answer your "so what?" this makes them a bit handier, especially for things like home defense. Compared to a handgun they are a more stable platform with a longer sight radius, greater magazine capacity and more options for things such as weapon lights and various accessories.
But back to the merits of something like a HK94.
Zero felt recoil. So what? Well I did cover this. Zero felt recoil means rapid target acqusition and greater ability to engage mutliple targets faster. This isn't all that important at the range but if you have 3 armed crack heads in your home it gets to be sorta important.
Less real world penetration of building materials. And since I guess you missed it, I'm comparing it to rifle/carbine calibers such as .223 (which is why I specifically cited the FBI materials test). As for the "so what" this means fired rounds are less likely to pass through multiple walls and as such pose a less significant risk than most rifle/carbine calibers to those in adjoining rooms or even neighbors. This is an important consideration for those who live in apartments, condos or town houses.
None of this is "spin", just the actual difference between semi auto pistol caliber carbines and actual pistols. To suggest they are identical is simply not true. The only thing they have in common is the round itself and generally the performance of that round, although carbine tend to produce a more accurate shot due to being a more stable platform with a longer sight radius.
