The mags can be taken apart, but unless you whip up a jig that correctly supports the body when you're diddling with it, and apply a few other tricks of the trade in the process, it may cause more problems than it is likely to solve. Though not necessarily perfect, MecGar mags have an excellent reputation for function.

I've never heard of this as a solution to the problem, and without making some comparisons to other mags they've made, I have my doubts that this is indeed the cause. You might try swapping mags with someone who has a "proven" one that works fine in at least one other Luger. I'd do it, if you're prepared to cough up all the necessary postage... But first let's see what light other comments may shed upon the scene.
