I got a few of those plastic P-Mags or whatever they are in the 20 round size and never use them...I am a gun club duffer and bought a bunch of those stubby metal 5 and 10 rounders because I only ever shoot 5 at a go anyways.

Today in the gun shop they had P-Mag 10 rounders so I bought a couple on impulse and when I got them home I laughed like hell...these ones have a cover on the top of them to completely seal up the mag! I'm sure you speed freaks and run-n-gunners would appreciate having to stop and pop the top on a mag before ya slapped it into your AR, LOL! I suppose that cover-thing is to keep the cartridges fresh longer...? :)

These plastic mags will no doubt work just fine for an old Fudd like me...but what about you speed demons and squaddies out there? Will they stand up the the chit and abuse you guys dish out?
 
The covers are to keep sand/dirt/mud out of them when you're carrying them on your vest for a living.

You do realize that soldiers have been using Magpul P-mags for years now......?

I've seen them advertised but I don't run with any military guys. If it's good enough for them, then it is certainly more than good enough for me!
 
PMags stand up to shyte and abuse... mine get dropped on concrete, run through mud, etc. They run well.

The ATRS pistol mags are pretty good too.

Inferior plastic mags (*ahem* PCV among others) are brittle, Crack on impact, and flex a lot causing issues.

As stated, the clip on covers are meant to keep dust and mud out during storage/transport. You take them off when you load out your gear.
 
I bought a 5/20 PMag for my LR308. It certainly works okay, but I did notice that the slightly rough texture of the mag body made it a little resistant to being quickly slid into place in the magwell. Smooth metal mags go in a little easier if your angle isn't perfect....YMMV
 
Pmags are a fine durable Mag as are the IMI Israelis defense plastic pieces. IMO I like the feel and looks of the IMI magazines over the others.
 
I just finished a CQB course and ran 5/30 pmags the entire time, I went through 500 rounds and dropped the empty mag in the dirt every reload and my rifle didn't have a single failure to feed.
If we could just drill out that stupid rivet they would be perfect.
I also have a couple if the Hera Arms 5/30 and they seem to be pretty well built as well. I've heard of a couple other brands that make good polymer mags but haven't tried those.
The metal mags are good and they're reliable but are much more susceptible to damage if you step on them or drop them on a hard surface. None of that matters at the range but if you compete or just like dropping them on a reload then you may have problems with them.
I prefer to use the 5/20 mags at the range during load testing while shooting off bags as they give more clearance below the rifle while still having enough to grab onto for loading and removing the mag.

At the course I did notice that the guys running LAR mags were having more problems than the guys running pmags or ATRS mags.
 
I feel like this question could have been entered with Google.

Alas, pmags are awesome, and so are lancer mags. I prefer the feel of the pmags, but the lancer mags have steel feed lips which is nice.
 
P-Mags are good, but I actually prefer the Troy Battlemags. They don't have flared bases and fit in pouches better than PMags (especially Gen 1 or 2). Also, I find the scalloped body is nice and grippy when it's raining like it does most of the year out here in BC.
 
My preference is for the Lancer L5 AWM's or HK polymers for plastic mags. Nothing wrong with Pmags (I have lots)...just my preference.
 
The tango down mag is supposed to be the most bomb proof based on some rather entertaining " testing" done by someone at ARF years ago. I guess it is not too successful because it is a bit ugly.......
 
Not a fan of hk polycarbonate mag. They are very short so if you have some 77gr smk loads that are seated a bit farther away the bullet tips may hit the mag wall. The thumb pressing baseplate opening mechanism is a direct translation from G36, and it can be very difficult to take apart.
