Springfield 1911 Custom Loaded: Series 70 or 80?

[marklbucla]

I was thinking of ordering some parts for the Springfield Custom Loaded 1911 line. Are they Series 70 or 80?

Series 70

Neither.
A Colt with a collet bushing is a Series 70. A Colt with a firing pin block is a Series 80.
A Springfield has neither collet bushing nor firing pin block, but it does have the ILS key lock mainspring housing and odd size titanium firing pin.
Some people will call it a series 70 because it lacks the firing pin block but that does not mean all parts interchange with Colt spec stuff.

What parts do you want to buy?
