M1 Carbine 10 Round Mags Made In USA

[imntxs554]

Here is just a couple of picture of the difference between Korean Mags and Made In USA Magazines, I have both and the the ones i use from the USA are so much better. The Springs are just like the 15 Round GI Magazine, but since to me they look like Cutdowns. How do they know how much tension you need of the Spring to get it to work right ? Im showing the difference sizes between the 5, 10 and 15 Rounds Mags and of ourse these mags are Parkerized (the 5 and 10). I wish i knew how to get these pictures in the correct positions.
