The cruiser racks we use won’t hold the gun with a 30 rd mag in it, so they’re in the racks with 20s, and 30s are on hand for spares.
Or out of a tennis racquet bag.
I plan on using them for zeroing and High-Power matches. :rolleyes:
I prefer 30 round mags for prone shooting as they make a much better mono pod. 20 round mags don’t serve much of a purpose for me. But I did buy 2 of them from Brownells for my collection.

I usually use a 20 as my in-gun mag on my truck gun…
AIM Surplus has them now too.

I’ve been running (20) OD Green 20rd PMAG’s for the last couple of months. Drake sent me some to T&E. They have been flawless, work just like the 30rd mags.
I can see how they would drop free, but how would any magazine lock-up in a stripped lower?
I am on the same page with you, especially at the same price as the 30 round mags. 
Sorry, I should have explained a little further. The 1 DPMS lower has a Stag LPK and the other has RRA LPK.
edited: varoadking, what I would personally try is push the magazine catch button in with a screw driver or something and on the other side turn the magazine catch 1 or maybe 2 turns counter clockwise to loosen it a little bit and see if that gets the pmag to lock in. This is the first time I’ve heard of PMags not fitting in DPMS lowers. But then again, I’ve been out of the loop of AR’s for several months.
I just got two of them in to try and one has already made it into my duty rifle. I was amazed at how much lighter and livelier it made the gun feel over a 30 rounder. As I spend much much more time clearing buildings at work with it than shooting, I figured lighter was better versus 10 extra rounds. There are still plenty of 30 rounders in the go bag however.
The other thing I am looking at is carrying the other 20 rounder on my duty belt so I always have a spare mag on me. The 20 rounder even with the ranger plate is really no taller than my radio, pistol mags or mace. I’ll probably end up with a blade tech holder and it should disappear with the rest of the gear.
I got my shipment in today. They are nice. I’ll have to set aside some for myself before they all go…
It also seems that Brownells is charging $1 more than MSRP. MSRP is listed in the 2008 Magpul catalog as $13.95

Can you snap some pics of them side by side?
Thanks for pointing that out. Kinda sucks, but oh well at least I only ordered 2 from Brownells.
Problem solved…
…remove dust cover before inserting magazine…
DOH!
UPS showed up just as I was walking out the door to go to the range. It should come as no suprise, but they work.
I wasn’t real excited about the 20’s until we got our first shipment in. I had forgotten how handy the 20 round mags are and the 20 round Pmags are even better.
My 10 year old son likes them because he shoots an AR off the bi-pod and the 20’s will help him.
Lancer may be developing a 20 round mag as well.
I just need some 5 round polymer mags for hunting;)
We have them in stock as well.

Got 2 yesterday plus some P-Mag ranger plates! I love these little magazines!
