Removal of Kimber firing pin safety?




Is a 'spacer' required when removing Kimber's 'Swartz-type' safety from the frame as with the Colt Series 80 frame-mounted safety parts? Personally, I cannot see how a 'spacer' could be installed, but am being told that one is required. TIA

You are being told that because it is true for Series 80 equipped pistols. Yours isn't and doesn't need a shim as the sear and hammer can not slide over whether the push rod is in place or not. So, no, it isn't.

While I can't push it over far enough, there have been reports here of the nose of the sear catching the top edge of the milled out recess of the push rod when it is removed. Not very common but apparently it has happened.

Perhaps so, I haven't any experience in doing that as tuning the firing pin block is a better way to go and keep all the parts intact and functional which is always my first choice.

I'm swapping out the trigger and thought as long as I had it apart. I also have a Series 70 firing pin to install. Oh, well.......

Just put a GI firing pin in the pistol (so-called Series 70). Leave all the other parts alone.

The firing pin interlock (and all its levers) will still be there, it'll just never lock as the block has nothing to block in the firing pin.

Yes, but the block will still drag against the pin, why not time it if need be and then there isn't any question, all the parts working as intended.

It doesn't drag.

The interlock will still lift when you depress the grip safety and be well clear of the firing pin.

And if it did drag, it won't drag enough to affect function.

If it is timed correctly, and if so, why disable it. It is a safety just like the grip safety and thumb safety. The 1911 will operate just fine without those also. I like to keep things intact and in tune.

Series 80

Mine just fell off (actually flew off) when I pulled out my firing pin. And of course unlucky me, i lost it.

So,I had to purchase the plunger & spring from Colt.

But I guess, that plunger safety is somehow linked to the grip safety, because I reassembled the Colt and the grip safety doesnt work, the hammer drops.

The Colt Series 80 firing pin block is activated by the trigger, not the grip safety as Kimber II's and S&W with there own version of the Swartz safety. Your Series 80 may not have been reassembled correctly. If the hammer will drop with out depressing the grip safety, it, the grip safety is at fault and can be welded and re-fit or replaced. Here's the Series 80 parts.

As noted the Kimber and Colt systems are different.

There is no reason to remove or bypass either of them and they represent an additional safety feature found in most modern pistols.

The Kimber system is more complicated with a plunger and block in the slide controlled by the grip safety. Colt system just uses the plunger controlled by the trigger. Either is easily defeated or removed entirely but the Kimber system requires removing the rear sight to get at those parts.

If you really don't' like the Kimber system just replace the firing pin with a standard (AKA series 70) firing pin and you can leave everything else in the pistol. Easy to stick the original firing pin back in before sending the pistol to Kimber for warranty service.

It is possible to reassemble the Series 80 parts so that they will fit and the gun will not fire. Don't ask me how I know..

When I installed my night sights, I discarded the plunger & spring. My gun still has all the frame goodies, and functions perfect. Mine was out of time, and now with the plunger & spring gone, the grip safety pushes easier(No more two stage spring feeling)

I never liked the idea of the Series 80 FPS, until I got one on a Taurus. After using it, taking it apart and putting it back together a few times, I have to admit it's a good system and has little to no effect on trigger pull. To me, the 1911 is a better, safer pistol with the FPS.

It's safer only if the pistol is dropped on it's muzzle. According to Dave Dawson, the Series 80 set-up adds about 4oz to the trigger pull, a negligibale difference in a carry pistol, IMO. Evidently it's an irritation to the competition guys, a lot of whom remove it and put in the spacer..

I've read of series 80 lifter arms bending and stopping function. That's enough for me to eliminate it. A lot of people hate the Swartz safety more, but to me if it's in time it's better than the series 80 because it doesn't involve the trigger at all.
But one reason the last 4 1911's I've bought don't have either system is because it seems to me to be unnecessary complication. Now, if they pad the outside of a 1911 thick enough, then if you drop it from a tall building it won't kill someone on the street when it hits them. I hope no lawyers for Colt or Kimber saw that!
