Anybody here use them? I’m working on an AR9 pistol and wasn’t even sure mags under 32rds existed. Found ASC (among some others) makes 10rd and 20rd versions. Seemed to have good reviews, but I’ve never used an ASC mag of any kind. I have four of them headed this way, but figured I’d ask.
 
I have the 32s. Work well.
Took a hammer to one or two because they flared where the feed lips bend in and also the bolt drug just a little.
 
I didn't have a great experience with my 20s in my AR9. They were hit or miss so I sold them. Colt makes 20 rounders and the cheapest I've seen them is at Greg Cote LLC. I haven't ordered any yet but will order 2 or 3 soon.

I see Metalform 20 rounders, but not Colt brand. Is that what you’re referring to?

My ASC will be here today, so at least I can look at them.

Yea. Metalform makes the Colt ones, and Brownells, and did PSAs when they sold them. I meant metalform/colt pattern not Colt branded, my bad!
 
Also, to be fair, my feedramps may have been dirty when i was running the ASC. But part of the problems I had were when there was an empty mag, using the charge handle to pull the bolt back, the bcg drug the follower and I know removed some plastic at one point. Pretty sure it did it with both my CMMG and Brownells branded 9MM BCG. And I know I had some failures to feed/cycle. I probably could have spent more time diagnosing the problem, but with my limited time to shoot, I just assume throw in a 32 round metalform and let it sing.
 
I haven’t had any issues with my 32rd PSA (Metalform) mags. Read a lot of good reviews on the ASC, and wanted to try something shorter in this build.

...just wish the upper would come back in stock. :(
