Ok guys , what can you tell me about the above handgun ? How does this differ from the 1911A1's that where issued to our GI's . This is the " Goverment" model what are the main diffrences ? The main i see are engravings and the 80 series has a satin type finish ? Diffrence between MKIII vs MKIV and 70 vs. 80 series.

Series 80 has a firing pin safety that is deactivated by the trigger pull. Series 70 does not. I own a series 80 and it does increase the trigger pull a little bit. Also, I believe the GI/ series 70 had shorter triggers

So just the trigger pull and pin safety ?

Series 70 colts are regarded by many as the most well built 1911's. If you handle one, you can tell they were built to be quality pistols. Series 80 are simply not built to the same standards, many complain of machining marks, burrs, badily fit..etc etc.

Perhaps - but I the even earlier ones (post WWII) are my favorites. Those babies feel hand made...

In any event the Series 80s are the current version production Colts (there are also S70 reproduction Colts made without the Series 80 safety - but not available in CA); they are generally nice in my opinion. The XSE model is a great shooter in my opinion (although some don't like the front cocking serrations), and the standard government models have quite a following.
