I never could figger USMC individual weapons training.
For the rifle range, we were so wrapped up in leather strapping that we could have been mistaken for..................never mind.
For the pistol range, we shot the M1911 w/the extended strong hand only, no weak hand support. (Weak hand was supposed to be properly stowed in the trouser pocket.) Aim in, slowly squeeze off each shot. Handgun waving in the breeze. Sometimes we hit the berm; sometimes not. Everyone griped about the "inaccuracy" of the M1911, but officers and NCOs proudly carried them on their hips in the US flap holsters.
Now, when we ran Combat Town drills for advanced infantry training (a little simulated Korean village) where I frequently worked, the scenario was more real. Everyone just ran through and shot the hell out of everything in sight. Standard USMC drill. Shoot long enough and loud enough, Something Dies.
MyThink is that the USMC (and maybe all military branches) ought to run some form of IDPA/USPSA for all handgun, rifle, and all other shoulder/squad fired weapons training. C/mon....Let's MOVE!!!!!
But--Of Course--No One's Gonna Listen.
