Series 70 Build On Series 80 Frame?

[sasquatch981]

Hi

I am fairly new to the 1911 scene, but have a general understanidng of the workings of a 70 series pistol as I have an STI. Is it possible to build a 70 series pistol on a 80 series frame? Or are the cuts to the receiver made in such a way as to not allow it? The reason I ask is that Caspian has Recon Rail- Receivers on special, and I thought these would make a nice L10 gun. Thanks for any help.

Converted my Colt series 80 to series 70 and my para . All you have to do is buy the spacer kit ( I am not sure if this the right term) from brownells.

Converted my Para as well. Here's the part:

in addition to the spacer you will want to put a 70 series style hammer that has the half-cock hook, since you will lose that safety feature offered with the 80 slide.

I had to convert my Colt from 80 to 70 when I added a bomar rear sight. The milling of the slide made it to where the hole for the firing pin safety came right out the top of teh slide. At 1st, I didn't change the receiver of the gun at all, but I found that the lever that depresses the plunger in the slide was getting caught in the hole where the plunger was. I had to grind it away.
