Magazine Problems

[USMC_Spike]

After reading through many of the posts here,
I purchased a couple of the magazines.

I got two of the Mec-Gar nickle magazines.
After putting some rounds in them and pushing
the rounds out of the magazines, I was shocked
to find they caught. That is, the ammo got stuck
on the magazine, where the case and the bullet meet,
as I pushed the round forward.

I then checked the magazine that came was with my pistol
and it is an Erma magazine. I did the same test with
it, and not one round caught. I did the same check with
other pistol magazines, .45 and .380 and didn't have any
problems with them. There are cut aways where the
round exits the magazine where there are none on
the Luger magazines.

Upon closer inspection, the Erma magazine is tapered to
a point, at the top front of the magazine where the magazine
feeds a round into the chamber, the Meg-Cars are not tapered.

There are some other slight variations too, in the shape of
the plate that pushed up the rounds in the magazine. I'm
wondering if this plate needs to be bent slightly upwards?

I'm also wondering if I should try and grind down that top
part of the magazine, any thoughts?

Anyone else have this type of magazine problem?

I'm beginning to understand how finicky these pistols are
and appreciate the Browning designs of the 1911 and
the 9mm hi-power for reliability.
