Quoted: I have a romy g build that I complete about 6 months ago and I'm looking to purchase more mags.  I get a bit overwhelmed looking at the EE with all of the different variants. Is there an online store I should go to?

All good people with good prices

Which variant should I buy?

Avoid US made magazines and Bulgarian "slab side" and "bullet side" polymer magazines.

Imported steel mags, Bulgarian waffle mags, or "collector" mags like bakelites, aluminum waffles, and steel slab sides are all GTG.

I'm looking for 1 or 2 poly mags and several metal (standard) mags.

That's generally a good plan. I like to have a half-dozen or so Bulgarian waffles with the rest being steel.

The waffles are nice because they're light and more dent and corrosion resistant than steel mags, but the steel mags work just as well, of course.

Get some 20s, 30s, and 40s, too.

The 20s are nice because they allow easier prone/bench shooting, and fit in AR mag pouches. The 30s are standard and AK-specific pouches are generally designed for them. The 40s are nice because they're the most "space efficient". What I mean is that six 40s hold the same as eight 30s, etc...

I'm not trying to spend all of my money, so cost is somewhat important to me.  I would like to purchase from 1 place to save on shipping.  Suggestions?

Quoted: What about Pro-Mag AK mags, any good?  Copes seems to have several varieties . . .

If they were six bucks I could see buying a few if you needed some mags and didn't have much money (and intended to buy better mags when you could afford them).

But they're not.

They're the same price as MUCH better steel surplus magazines.

Buy the steel mags.
