Now that I have one. Being an almost 80 year old guns, and while it was rebuild by an arsenal decades ago, I am sure the springs are shot and mags are trash. The mags are old as Hell too.

Is there a spring kit I should look into? Aftermarket Mags?  All my mags for it are seemingly USGI mags. Prob wore out. Some were fully loaded for years

Just run 15 rounders.  Springs are available.

All but one of my surplus mags run but the kci's have noticeably stronger springs.  They have been 100% so far as well.  Nothing wrong with grabbing a bolt tool and spring kit just incase it has an issue.

Are you having cycling problems?

Why not just shoot it first and see how it works.  I have owned many carbines through the years, and I can't think of one I've had to change springs on to function reliably.

Shoot it first.  Unlikely you'll need to do anything.  It's  a pretty forgiving platform.  The mags are probably better than you think.

Haven't shot it yet. I was just figuring to ensure it runs great from the get go.I might need to look into some springs and what not  as some of the mags sat loaded for 20 years

Go shoot it, it'll probably run just fine

I recently picked up one of these kits and plan on eventually replacing all the springs, parts, etc. in mine when I find the time.
As it is currently it will have some FTFs/FTEs with certain ammo types.
Hoping new springs will make it run smoother.

I have two US GI Inland.

Woolf gun spring kit for both.  

Original GI mags run great.    KCI mags are thinner than GI and seem to wear quickly.    They run, but they won't see 70 years of use.   I bought about 10, and I will not be buying anymore.

Keepshooting.com makes M1 Carbine magazines that are as good as or better than original GI mags.   I have bought 2 dozen 15's and a dozen 30's so far.    They go out of stock and/or on sale now and then.

The only pring I have ever had to replace on a carbine is the recoil spring.  That got it back running 100%
