I need some help here guys...
Back during WWII through to today...I need to know what the
discernable difference was between civilian .45 ACP and military .45 ACP.

Also, was there ever .45 ACP made with tracer projectiles?

If any one here can help... please do inform me...best if you can link me to where I can
also document this information.

Thank you,

WOW! That's a tall order. You need to do some reading and research since books have been written on some of this stuff...some links below for you to start

And I do believe I have seen some old .45acp tracer from WWII or thereabouts, but I can't recall where just now. I'm pretty certain they did make it since the caliber was also used in the Thompson Submachineguns that were popular for close range fighting all the way up through VietNam days.

Tracers, Yup...you can still buy em.
