Plenty of demonstration and tests done by different folks on the internet, most agree GI mags don't perform as well against Pmags.

"PMag internal geometry uses an aggressive constant curve to improve reliability (the USGI has a curved then straight section to work with the M16 straight mag well)
PMag has a corrosive resistant stainless steel spring, USGI uses stock music wire
PMag has a 4 way anti tilt follower as standard (only very recent USGI mags have this)
PMag has a floorplate that is easier to remove and more robust than a USGI
PMag body has better crush strength than a USGI
PMag feedlips have better impact strength than a USGI
In combat deployment after-action reports, the PMag far out lasts USGI mags in theater.
PMag is functional after a 500 hour simulated salt spray test (the USGI fails)
PMag has a much much lower IR signature than a USGI
PMag body is easier to handle in both extreme hot and cold temperatures."

Sounds like the magpul salesman.

Yes yes, if its on the internet then it is always true right?

Obviously you have not shot that many rounds through your AR.

My pmags cracked - it does not flex back. I broke the lip of one pmag m2 last year. Meanwhile my pre ban colt usgi 20 rounders work all the time.

PMAG is an upgrade for sure.. but to say that USGI metal mags are shitty... is extremely armchair general like.

IMHO HK sa80 is the best... but folks in the field hated their hk416 mags. I shoot few thousand rounds through mine every summer... they work wonders for me.

USGI mags are my go to mags and pmags are my backups. Never owned a plastic mag of any kind until a few years ago. Just always preferred metallic mags.

I run both. I don't have any 20 rd pmags so i run 20 rd colt straight mags when on the bench. I usually use and abuse my pmags and keep my gi mags in like new condition at home.

I'll chime in. During the 6 years I've been in the Army, I have only had my service rifle jam when using the shitty unit-issued GI mags. Three years ago it was so bad that I vowed to never again forget my pmags at home when going to a shooting clinic/competition/qualification range with the Army. Have had 0 issues since.

Yes my rifle was always cleaned and lubed properly, I haven't changed that since I joined. Could just be dumb luck, but I blame the magazines.

I like 'em both. There are pros/cons to both.

PMags don't fit in all guns designed for the GI-style mags. Also, I have several Colt USGI 20-round mags from the 60s that are still going strong, original springs/followers, etc. None of my PMags from the 60s work.

Here is a link to David Fortier's article where he tested a variety of magazines. I'll find another link with the photos.

Yeah, but hey, what kind of mags did they use to kill Osama Bin Ladin?

Wasn't that an MP5 with and HK 9mm mag?

I've not shot as much as I would have liked but over two Bushmaster AR's I have never had a issue with a GI mag.
