Karambit Posted August 4, 2011 Share Posted August 4, 2011 (edited) Just received a new 140mm .45 mag. PROBLEMS: I can't load more than 10 rounds without using extreme force. When I tried stripping off a few rounds the rounds started to nose dive. After stripping off the nose dived round three rounds tumbled out as the follower didn't move. Any suggestions? Edited to add: I just loaded 6 rounds and I can see round 5 is nose diving. I stripped off round 6 and round 5 didn't move. Shaking the mag sounds like a baby rattle.

Round 1 is stuck at the top most hole in the mag Link to comment Share on other sites More sharing options...
UW Mitch Posted August 5, 2011 Share Posted August 5, 2011 Should hold 13 round IIRC. Have you taken the base plate off, removed the follower to see if there's a burr somewhere? Or maybe it's a Cal-legal mag with a dimple preventing more than 10 rounds? My standard thing when I get a mag is to go through the steps outlined in the Dawson Mag tuning kit. Basically using some 400 grit sandpaper wrapped around a piece of aluminum to deburr the inside, deburr the feed lips, make sure the lips are right, check and make sure nothing looks weird with the spring and follower. Usually I put in a Grams Spring/follower and on a couple mags still use the stock floor plate. Sometimes these things take tinkering. ~Mitch Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 5, 2011 Share Posted August 5, 2011 Hello: First thing is to clean the mag inside and out. Next is to check if the follower is dragging in the mag tube. Thanks, Eric Link to comment Share on other sites More sharing options...
walter hornby Posted August 5, 2011 Share Posted August 5, 2011 Also check your bullet length Link to comment Share on other sites More sharing options...
Intel6 Posted August 5, 2011 Share Posted August 5, 2011 (edited) Check your loaded round OAL. I had that same issue when I got my .45 ACP Eagle. I tried some ammo I had loaded for my Spartan and it would only let me load a handful of rounds before it stopped.

feederic Posted August 6, 2011 Share Posted August 6, 2011 I could only get 9 in mine until I lowered my OAL Link to comment Share on other sites More sharing options...
Karambit Posted August 13, 2011 Author Share Posted August 13, 2011 Thank you for the suggestions. I think they must have sent a .40 mag in a .45 package. I sent it back on their dime and will be getting a replacement soon. Best to all. Link to comment Share on other sites More sharing options...
Intel6 Posted August 13, 2011 Share Posted August 13, 2011 Easy to tell the difference. The .45 mag will have shallow indent grooves on both sides of the mag body and the .40 will have shallow indents like the .45 Mag on the right side of the mag and deeper indentations on the left side of the mag. If the indented grooves on the sides of the mag body are the same then you have a .45 mag. Neal in AZ Link to comment Share on other sites More sharing options...
feederic Posted August 14, 2011 Share Posted August 14, 2011 I had to lower OAL on mine too just a tad, that made the difference between 8 and 13 rds. Link to comment Share on other sites More sharing options...
