It may very well just need a new set of springs all around. Magazines and gun.
I have been told that commercial ammo may be a culpret also as it is not as hot as the military stuff the guns were designed for.
Just my two cents. We have an M1 carbine that I am going to replace the springs on soon. Two magazines work great the others have weak springs, no doubt. I am also going to replace the springs in the gun since they are about 60 years old.

As a general rule of thumb, when the M1 Carbine has cycling problems, the first thing to do is a strip and good cleaning.
Inspect the extractor and ejector assemblies for fouling or worn/defective parts.
Next, inspect the gas piston assembly for free operation. If not it needs cleaning.
If the gas piston assembly is fouled, you will have these problems.
You can disassemble the gas system and clean it yourself.
All you will need is a gas piston nut wrench (available from many sources) and a GI manual that shows the correct method of removing the assembly without damaging it.
When you clean the unit, DO NOT use any sharp instruments. Scrape it with a piece of brass, a brass brush, or a Lead-Away cloth.

I've got one that jams just like that, but only with cheap non-G.I. magazines that I got from the "Dumber Than Dirt" catalogue. Good mags make it run like a top.
Are you sure your mags are up to snuff?

I agree that the gun springs should be checked and replaced if necessary. I'd also suggest a good cleaning, proper lube, and good mags. However, as for the ammo, my chronograph testing showed current factory ammo to duplicate military loads. For example, PMC 110 grain FMJ gave 1929 fps; Winchester Super-X 110 grain HSP gave 1918 fps, and USGI RA54 Ball gave 1918 fps.
Sounds like one of 3 problems to me:
#1: Bad mags
#2: Bad Ammo
#3: Need new springs. This is probably the one, my Dad's M1 carbine needs new springs and it has the same problems that you described.
The M1 Carbine is a great gun. I learned how to shoot on an M1 when I was about 5 or 6, and to this day it is my fav "assault rifle". I know alot of people don't consider it an assault rifle, but it is semi-auto (full auto if you count the M2), has hi-cap mags, and shoots a smaller-than-fullsized rifle round. Anyway, it's just plain fun to shoot...

Although the correct answer is probably been posted, you'll get a better indication of which it is answer if you define "jam". Fails to extract, fails to eject, fails to feed, etc.
