Lost Firing Pin Plunger Spring?

Item number 32 is for a series 80 only. is your 1911 a series 80?

Been awhile since I removed the series 80 guts from my Remington 1911(and no, it is not a BE gun, so no rules broken

If I remember correctly you need to push in on the plunger a bit and then it releases the firing pin for removal.
If the pin did not come out, I do not know how you lost the spring below it ???
For test firing I just take a lead pencil and drop it into the bore with the eraser end down.
Fire it and it usually has the momentum to strike the ceiling from a seated position a few feet from the floor.

To remove series 80 firing pin, the plunger is depressed which allows the firing pin & spring to pop out. The firing pin plunger is held in by the extractor. Therefore, depressing the plunger allows the extractor to be removed. Then, the plunger and spring will pop out. The only way to lose the spring is for the plunger to pop out when the extractor is removed. Springs are available often on ebay and Amazon among others. When looking on line for the spring, be sure you're looking at the firing pin plunger spring NOT the safety plunger spring.

I believe that Cylinder And Slide has replacement springs and if you are interested in slicking up the works a little they have a TiN coated plunger and levers too. That's assuming they are the same in a Remington as in a Colt Series 80.

Its a Kimber Gold Match II which has the fire block safety.  The manual is a PDF http://www.kimberamerica.com/media/wysiwyg/manual-download/1911Fullsize45.pdf.  On pages 34/35 its referenced by parts 39 & 40.  It appears the assembly is via the top of the slide and under the rear sight.  I don't have a rear sight as it was removed when the scope rail was installed.  They reference an illustration on page 12 that describes the firing pin block.  I guess, I'll have to pull the ultra dot off and see whats under there. Still can't imagine where the damn spring went.  Such is the nature of springs under tension....  

The beavertail safety grip works normally but I have noticed that if I hold the gun upside down I can dry fire it without engaging the grip safety.  I guess that's the whole reason for the spring.... I've never seen anyone try to fire an inverted gun, but one can never underestimate the stupidity of the human species. 

OK now we all know it's a Kimber and you have identified the spring in question. Only way to lose that spring is for you or your "gunsmith" to have lost it when removing the rear sight for the rail installation. Really should put in a sight blank to retain the spring. Or, do what I do: shorten the rail and keep the rear sight in place.
