get the known manufactures and STAY AWAY FROM USA MAGS, other then that colt, busy, labelle, parsons, d$h okay industries and more. those are some of the best mags on the market, i dont much prefer the plastic mags so stick with usgi unless you want hk!

Go with USGI mags only.  I personally prefer NHMTG mags but any USGI mags will work

usgi are good to go

Get your Colt magazines here

USGI Mags are great. I have also had good luck with Thermolds. But I recently gotsome HK mags and thats what I am using from now on.

USGI mags (see Troy's mag faq):

Colt (actually made by OKay)
Universal Industries (also made mags for Colt)
Simmonds Precision Products
Okay (who are also NHMTG)
Adventure Line, which became Parsons, which became Center
Labelle, which became General Stamping, which became D&H
Labelle also made mags for Bushmaster and DPMS

The one USGI manufacturer to be leary of is Cooper Industries.  First examine the spot welds.  There should be a minimum of 6 spot welds on the front seam and 6 on the back seam.  Some Coopers only had 3 welds each seam.  Even if the body appears to be perfect, discard the spring and follower and replace with a new spring and green follower.  The reason why, in the '86-'87 period a gazillion Cooper mags were dumped on the surplus market, many NIW (New In Wrapper).  They had weak springs causing misfeeds in the last 5-7 rounds.  With good springs and followers these mags can sometimes be made to operate well.

In my personal experience, many Orlite mags have cracked feedlips, or they will soon crack.  Many are quite dirty, with sand embedded inside.  For a few dollars more you can buy a good new USGI mag.

Thermolds, sometimes OK, some will not fit in some mag wells.

Eagle and Ramline smoked transparent plastic mags... functioning problems, not reliable.

USA, not reliable, feelips not "boxed" at the corners and will spread with time and use.

Sterling 40 rnd, good mag, very rare and expensive.

PMI aka Federal Ordnance 40 rnd, reliable, good quality.  The older Federal Ordnance mags are not marked with name on the floorplate, so you may not know one when you see it.

stick to USGI mags ONLY!

there is a mag faq tacked at the top that should aid you in your decisions.
