series 80 disassembly problem

[mousemouse]

this is my first pistol so i have no experience with detail stripping. I field stripped it after every range session with no problems, now i want to detail strip it and i am stuck. I can't get the firing pin stop to get out.

I looked at guides in the web and followed the instructions. After pressing the plunger, i used a punch to push the firing pin and released the plunger to hold it in place. Now, this is where i'm stuck. The firing pin stop doesnt want to go down. I found a disassembly vid for a series 70 and the firing pin stop slid off easily after the firing pin was depressed.

Am i missing something? any tips?

Push in the firing pin a bit, then push down on the plunger a bit, and the firing pin will come out.

The plunger for the Series 80 firing pin safety is, as you noted, the key to being able to remove the firing pin and spring.

Fully depress the plunger, then use your appropriately sized punch to push the firing pin toward the front of the slide. Then, release the plunger, and the firing pin and spring should be captured, allowing the firing pin stop to be easily removed. You should be able to tell whether the firing pin clears the firing pin stop with a visual inspection.

Using your punch to gently start the firing pin stop downward might loosen an otherwise tight fit. Just be certain that nothing is binding, or preventing the movement of the stop.

Reassembly will be in reverse order, and you'll need to be sure the plunger and plunger spring are properly installed in order to capture the firing pin and spring.

i did this exactly.
1. depress plunger
2. push firing pin as far back with punch
3. release plunger, firing pin stop now clear of firing pin (i checked the hole with a flashlight)
4. try to push firing pin stop down using punch.

i tried pushing from the topmost part, but could not get anywhere.

The gun in question is a SS colt government .45acp, which was bought almost a decade back but never even tested. my dad gave it to me when he heard i was going to buy a gun. It was in a safe, neglected until given to me. There was slight rusting inside where the mags go in but i wiped it off with oil and it was gone. The exposed portion of the extractor near the firing pin stop also shows signs of rust. Could rusting between the frame and the firing pin stop be an issue here?

In a word, Yes!

Try some penetrating oil, in an attempt to loosen whatever rust or gunk is between the slide and the firing pin stop, then try to dismantle it again.
