Default Safety Spring

I have noticed recently that many people may not know that the short safety spring is used with a push safety. If the later longer safety spring is used, the push safety can be very hard to press. Many people removing a late flip safety and putting a push safety in their trigger housing may not know the spring needs to be replaced if pushing the safety is hard.
LR says the type 4 flip safety was adopted in March 1945.
Riesch says the longer safety spring was "improved" late in 1944.
So it appears there can be some type 3 safeties with late springs.
I have just found using the earlier spring with a push safety was just a lot easier to use.

Hmmm, I did this on my 6900xxx Inland and didn't notice it being hard to push. Guess I got lucky and already had a short spring. I know the flip safety is correct, but I'm more comfortable with a push...

I find myself going thru the stash and finding one that’s just right. The springs obviously wear over time. Short springs can be too soft and long springs too strong. I find the one that feels right.

Default Quick Easy Spring Check ...

It is quick and easy to conduct a quick and easy safety spring test. If the prospective USGI Carbine already has the flip safety, (and all of ours already do) rack back the slide, check the chamber, release the slide and flip the safety a couple of times.

Not for push safeties. Only later type flip safeties.

The feel should be firm. You might also hear a slight "click". If the safety feel is sloppy or weak one may have the wrong spring inside. Quick and easy to change out. We use the flip safety only for continuity and training purposes. Works well.

I had a spring that was too long for a flip safety. Ended up clipping a couple of coils to get it in far enough to install the mag catch. Eddie
