Ratings & Reviews
AWESOME MAGS!! The only issue i have with these mags is that i don't have more! Work perfectly in all my Glocks, and Glock mag running carbines.
Excellent, but with one drawback
<br>-Cheaper than OEM Glock mags
<br>-100% reliable with grass cased ammo
<br>-Lighter than Glock brand mags
<br>-Very unreliable with steel case ammo, rounds stick and will not feed, also very difficult to load with steel case too. I get probably 5 or 6 stoppages in 20 rounds. It usually requires removing the mag and smacking it against something to get the rounds to unstick.
<br>I will probably buy more, but with the awareness that steel case is a no go.
Perfect for a 9mm AR

Bought to use in my Foxtrot Mike AR 9mm. Locks in tight and feeds like a dream. Couple hundred rounds through with no problems. Will be buying more and waiting for PA to get the 30 Round Magpul. Only gripe is they are not fun to load beyond 15 rounds if you don't have an assist of any kind.
Works for my Ruger 9mm Carbine, no issues!

I just got a Ruger 9mm PC Carbine and needed "Glock" magazines, didn't realize when buying two that they are Magpul... but the price was right, and my PMags are my favorite in my AR. And it works just fine! The 21 round magazine is a nice length for the Ruger 9PCC, no failures so far.

These are P-mags, do they really need to be reviewed? I just wanted to say a word about Primary Arms, these guys are the shiznit! Ordered yesterday, received today! This is a great Texas company! Ordered after lunch and they still shipped them out same day. Great service guys! keep it up!
