Guide rod spring?

31H Retracting rod spring

Okay, thanks.

And to be sure, am I right in thinking that is the spring that is causing the slide problem, or is there a different spring i'm not seeing

Is the separation there causing any issues in firing or is it just a cosmetic issue?

I dont know. I havent fired it due to it not functioning 'properly' because obviously it didnt come from the factory like that. I was afraid to ruin anything. Not that I think I could, but still better safe then sorry. The gun means alot to me.... its part of a huge collection from my grandpa.

Would it be cool to fire it as is? Or should I fix the spring problem frist?

If you have doubts, it maybe a good investment to go to a gunsmith first.

Ditto !!!!!!!!!!!!

It's the recoil spring. You need a new one, or you might get away with turning
it around so the buggered part is on the rod.

Pasted from my other reply:

HD Military---If you want to remove the slide it's a little tricky.
Pull the slide back, then depress the little button on top and let
the slide forward. At that point there should be no recoil spring
tension pushing the slide forward. Then rotate the little lever on
the side forward and slide the slide off of the frame. If you don't
use the little button to lock the recoil spring back, you will trash the spring.
