I thought this was gonna be another "cartridge in the microwave" thread.
But alas, it's something else.
I have not tried the 3D thing.
However, I have held my camcorder up to my eye, using my L hand (yes, it is as awkward as it sounds), and looked through the viewfinder and lined up the sights that way holding the gun in my strong (R) hand.
Little bitty iron sights are kinda hard to see in the viewfinder, so accuracy isn't the greatest, but it is a HOOT!
