I am going to use Colt 80s slide, with firing pin safety plunger removed ,(necessary) on a 70s frame, for a build I am slowly progressing with.

I inquired here a few weeks ago if I need to plug, or be concerned about the plunger hole, and members were good enough to weigh in that I did not.

I had to be away from that project for a while, so no further questions about it till now. After further reading and listening, I find advice to use a lighter firing pin(titanium) and a stronger firing pin spring, if removing that plunger.... By the way, this is a range piece, and not to be carried except to and from the range.

I plan to use the C&S ignition kit (4.5 lb.) which has the main, and sear springs, plus hammer,sear, and disco.

I would not have thought the plunger would put so much pressure on the firing pin that you would have to compensate, if it were gone, and this advice could be for safety sake, but I would like an opinion from you 1911 guys. Thanks

Wolf extra power FP spring is what you need. They come with the recoil spring when you order a RC spring.

The plunger doesn't put pressure on the firing pin at all. It adds pull and drag to the trigger group, as pulling the trigger back is what moves the series 80 parts.

The extra power firing pin spring doesn't "compensate" for removal of the plunger - it simply gives you a bit more insurance against accidental drops causing inertia-fired AD's now that the plunger is gone.

The titanium firing pin with a heavier firing pin spring lessens the chance of the pistol firing by inertia if dropped in its muzzle. All part of California's efforts to make guns 'safe'. You can use your 80 series pin and spring.

Yep. A bit of extra insurance if you want it. It's a personal choice.

Thanks guys. When I first heard, (or read) for the need of a heavier fp spring I assumed it was a mechanical issue for function. Glad you cleared it up for me.

Among the first six replies you have better than thirty thousand posts ! Impressive.
