Hip firing is another example of liberal stupidity. Far less accurate. We all know this. Pistol grips suck at hip firing. Even PGO shotguns aren't really meant for hip firing.
Ever see WW2 footage of soldiers with Thompson SMGs? Many times (not
all times) they fire from the hip in Close Quarter work. Actually, perhaps a bit above the hip.
The ergos of the Thompson work out such that it is very comfortable to use this weapon in this way.
Putting the gun to shoulder sticks the rear sight almost into my eye.
The AR-15/M-4 platform, although ostensibly similar in layout as the Thompson is a better all around design and much better ... primarily because of the way the stock is designed. The way the Thompson's stock attaches to the lower and "droops" is a detriment, IMO.
You are right though about hip firing being inaccurate -- most of the time I've seen Tommys used this way in WW2 were in streetfighting where distances were pretty close a lot of the time. Aiming instinctively works pretty well that close.
