mikeg1005 Posted January 13, 2012 Share Posted January 13, 2012 Hey everyone. I'm new to the whole 2011 thing... upgraded from single stack and I love it. Anyways, Out of the mags I have, I have noticed that two do not fall freely out of the gun. The other ones I have, will shoot out as they should when they are empty, two of them(STI mags) will not. I will hit the mag release and they will not move. I have concluded that it is the mag tube dragging. As I pull the mag out I can feel resistance so its not the mag release, and the resistance is still there if I just use an empty tube so its not the follower/base pad. I'm going to use a marker and figure out where its dragging after work, but what are the fixes to get it to fall freely again? Thanks, MIke.

Quack Posted January 13, 2012 Share Posted January 13, 2012 You need to tune the mag. Some of the tubes are out of spec and can cause this. Link to comment Share on other sites More sharing options...
AWLAZS Posted January 13, 2012 Share Posted January 13, 2012 (edited) I attach sand paper to the mag tube and work the grip a little. I use a marker to see where the mag rubs and start on that side. Edited January 13, 2012 by AWLAZS Link to comment Share on other sites More sharing options...
TMC Posted January 13, 2012 Share Posted January 13, 2012 You can lightly squeeze them in a vise to make them narrower. I've done a few that way. Don't get too carried away though. Put the mag in the vise and tighten a bit and check in the gun, if it doesn't fit then go a little more. All the ones I've had to do were too wide front to back.

blaster113 Posted January 13, 2012 Share Posted January 13, 2012 sometimes the bottom of the grip will get chewed up a little from reloads. a slight bevel at the very edge of the magwell will help along with smoothing out any burrs up in the grip.

feederic Posted January 13, 2012 Share Posted January 13, 2012 Measure out the tubes that fall free with calipers, then try and spot the differences with the tubes that don't. Those tubes might be bowed or out of square somehow. Link to comment Share on other sites More sharing options...
Quack Posted January 13, 2012 Share Posted January 13, 2012 Front to rear tube dimension per Dawson mag tuning video is 1.370" Link to comment Share on other sites More sharing options...
Braxton1 Posted January 14, 2012 Share Posted January 14, 2012 Front to rear tube dimension per Dawson mag tuning video is 1.370" ...and it only takes about +0.010" to make them stick. They really mean it on that 1.370 spec! Link to comment Share on other sites More sharing options...
RippSpeed Posted January 14, 2012 Share Posted January 14, 2012 your mags stick when they're completely empty or have a few rounds in them ??? My mags dont drop free when the're completely empty Link to comment Share on other sites More sharing options...
mikev49 Posted January 14, 2012 Share Posted January 14, 2012 I have a friend that this happened to and it wasn't the mags. A litte light sanding of the inside of the grip and they all work great now. Link to comment Share on other sites More sharing options...
mikeg1005 Posted January 14, 2012 Author Share Posted January 14, 2012 (edited) Well after a lot of sharpie coloring, vice work and a little bit of hammering all the mags are good. 2 of the mags were 1.38-1.39" wide and the other was too wide sidways and needed to be pressed in at a few places. Everything works and I actually am able to get an extra round in one of the mags now haha. They now drop out empty and full.. and the tubes by themselves fall out fine so with the help of the follower/a round on top they shoot out great. MIke.

Quack Posted January 15, 2012 Share Posted January 15, 2012 good to hear. Link to comment Share on other sites More sharing options...
mikeg1005 Posted January 15, 2012 Author Share Posted January 15, 2012 Is there a dimension for the mag catch that is recommended. After tweaking the mags I had to adjust the mag catch openings for the mag release to let the mags go( light filing fixed it) . Just wondering if you go by feel or by a measurement. Thanks, Mike.
