Apparently, the huge cloud of smoke generated by the discharge of cast lead bullets is actually the wax lubricant burning off. I knew all those facts, but never put 'em together...also, 500,000 lead rounds apparently doesn't come close to wearing out a 1911 barrel, while 50,000 jacketed ones will shoot it out. Good to know.
Double-taps are hard. More precisely, double-taps work a lot better when you actually have a sight picture for both shots, and your grip is neutral such that the gun returns from recoil to the place whence it came, instead of seven o'clock low. I saw the sights there, so it wasn't a jerk/flinch (entirely), so methinks I'm overcompensating for something at speed. Runs OK slower, so...do the same, slower, but faster. Or something.
The original Ghost in the Shell movie is still amazing.
