Well I recieved my 12 round mags yesterday, and as expected they are not top quality (what are really gonna get for $6 a piece) But they look cool as heck.
Out of the box they sucked, wouldn't even allow a round to be chambered, it kept getting pushed out weird and would end up straight up and cause a stovepipe type situation.
The cure was.................................. I changed the followers and filed the lips down a little(they were very tight, you really had to work to get it loaded) and now they seem to function well. I haven't shot with them yet, but can't wait to try.

Yes - the two critical aspects - feed lips and follower.

It is worth comparing the angle appearance of top round with that in a known good mag - and adjust/tweak feed lips to match. Sometimes some metal removal works but also very minor adjustments with needle pliers can do too - just changing the flair angle etc.

Follower - well, gotta be free as free so - no snags anywhere on its travels.



Glad too they came thru - as we had wondered about the reliability of the source!!

Chris, I did have to get after them with a pair of plyers, as the feed lips were "crimped" instead of nicely "rolled" like my quality mags. When I first ot them the top round sat so low you had a hard time pushing it out with your thumb, and it wouldn't feed any of the rounds into the chamber. Now the top round sits exactly the same as it does in my other mags and it goes in the pistol nicels and feed every one (by hand haven't shot it yet) and drops free without a problem. So for $12 and a hour wirth of tinkering i got some cool range mags.
