Series 80 or series 70?

ahh, well actually any brand 1911 that will drop the hammer from half cock is in serious need of safety work.
the half cock notch is designed to actually be a safety in regards to the gun accidentally dropping the hammer without the trigger being pulled.
the half cock should catch the hammer on its way down unless the trigger is rearward.
do not confuse this with a series 80 safety system however.
The series 80 ( which this is not really the entire series 80 thing) but the idea is that if the weapon is dropped with a loaded chamber and it hits on the muzzle the firing pin is locked back to prevent movement of the firing pin forward and striking the primer causing it to fire.
as mentioned this safety feature involves spring, plunger and a couple of frame mounted extra lever to move all that stuff. generally you can get a lighter, less creep trigger with a series 70, but as mentioned most can not tell the difference in a 70 and a 80.
I wouldn't really worry about it unless I was after a competition 1911 myself.
the other guys have pretty much explained all the plus and minuses.

Thanks guys I tried pulling the trigger on both my 1911's in the half cocked position and neither one would fire I'll try to remember where I read that. I'm still new to these pistols and just trying to learn as much as I can about them and was usual you guys came through Thanks again

UMMMM???
Possibly a para LDA (Light Double Action??
I don't have one of those but would suspect that IF it has a half Cock then it should raise and drop the hammer?
these aren't 1911 of course but shows the same basic Firing pin block.
the EAA Witness in the top picture is a so called series 80, see the little button (in the slide near the rear?)
the second picture is of the CZ Shadow -2 , which is a series 70 , it has no such block as its a competition designed weapon.
notice no button on the underside of the slide.
hope this helps.
