spring in plunger tube




RIA Officer Size 1911.

Problem: THUMB safety stuck. To un-stick, must force the safety plunger into the plunger tube with a knife blade. Something is going on with the thumb safety/slide stop spring. Need to get the spring out for inspection or replacement. The plunger tube is tightly staked and not loose. The plunger tube doesn't appeared to be dented or damaged.

How do I remove the spring? Please give me some pretty detailed instructions as I am not a very good gunsmith.

TIA!

To get the grip-safety out, you need to remove the thumb-safety first so check out this video:

once the thumb safety is out, simply grab the plunger and pull it out.
You might need to grab it with needle nose pliers if it doesn't come out easily .
it only comes out one way...from the thumb safety side

The spring and slide stop plunger "should" come out with it .
(as they're all kind of hooked together)

if all of it doesn't come out, you'll need to push it out from the slide stop side toward the thumb safety side .

a 1/16" punch will do it
a tooth pic "might" work too ..or anything stiff enough to push thru the plunger tube
(if needed)

Grip safety stuck or thumb safety stuck? Plunger tube spring and grip safety have no relationship.

Thumb safety. How do you remove the thumb safety? I have the hammer cocked and have jiggled and wiggled the safety and it doesn't budge? Does it need to have the pin popped out from the non-safety side?

With the hammer cocked, place the thumb safety between on and off in the middle, keep pulling on it at the same time, wile moving the safety, a little both ways, you will find the sweet spot. watch your eyes because the spring will sometimes launch. there will be 3 parts that come out,the safety detente plunger, spring, slide stop detente plunger, the plungers are small, so be careful not to lose them.

^^ Ditto this. Nothing like seeing it done correctly first. It's actually pretty simple. Expect the spring loaded plungers to launch.

You have to remove the thumb-safety first to get the grip-safety out.

Edit: Now the OP has edited his post and removed his reference to thumb-safety only. Oh well.

FOLLOW UP...

After setting the thumb safety to mid-point as suggested and wiggling it came right out. Spring in plunger tube and thumb safety plunger have some mild rust and this is most likely why the mechanism stuck... Will clean plunger tube tomorrow and clean rust off spring and plungers and oil. Never oiled in there before. I do carry this pistol IWB and I suspect sweat or body moisture caused the rust... no rust visible on outside of pistol. Thanks!

I am leery about grease but I did put some grease in the tube and also greased the detent and rod part of the thumb safety. I am aware that grease catches grit but two plungers seem to work much better after cleaning and light grease.

Ambi. safeties on Series 70 Colt Govt.

Gentlemen:

Forgive me but I don't know how to start a new post.
This thread is the closest I could find for what I want to ask.

Have a Series 70 Colt with Kings Ambi safeties. They were installed 40 some hears ago. They engage fine but when they are disengaged they are very sloppy -- that is they disengage easily and are not crisp.

Will replacing the springs in the plunger tube solve this problem or is there another fix?

Thank You!

replacing the spring AND plungers will possibly make it like you want it.
However, if the installer of the safety cut/fit the safety's plunger cam point area for minimum resistance (or over cut it) you may need a new thumb safety.

a new plunger/spring assy is cheap and easy to replace though.
so that's where I'd start .
and i "think" they make extra power plunger springs too
