hornetx40 Posted April 1, 2013 Share Posted April 1, 2013 What defines a drop free mag.? Are all of the gen 4 mags considered drop free? Link to comment Share on other sites More sharing options...
Poppa Bear Posted April 1, 2013 Share Posted April 1, 2013 (edited) Early Glock mags were not fully lined on the inside (NFML). When loaded they expanded enough to keep the magazine inside the grip even when the mag release was pushed. I can be corrected if I am wrong because I am not sure about some of the not so common calibers which might have only been released as FML, but I believe only 1st generation mags were NFM, and ALL generation 2 and later mags were fully metal lined. So if a mag fails to drop free it is due to some other issue much like the occasional 1911/2011 mag that sticks because it is getting hung up on something.

hornetx40 Posted April 1, 2013 Author Share Posted April 1, 2013 Thanks for the help It's not just one mag so it's either dirt or something I changed on the gun. Link to comment Share on other sites More sharing options...
dvc40jim Posted April 1, 2013 Share Posted April 1, 2013 If you have a magwell on the Glock check it, I've seen magwells cause it on both Glocks and STI/SV's. Link to comment Share on other sites More sharing options...
lee blackman Posted April 1, 2013 Share Posted April 1, 2013 Taylor freelance makes non-extended and extended capacity basepads made of brass for Glock mags. The added weight should assist in getting your mags to drop. It doesn't take much dirt to hold an empty mag, or make it slow to drop. Keep it clean, and practice pulling them manually with a mag already in your hand to reload just in case. Having a mag funnel brush, or even just a toothbrush at the matches is never a bad idea. They sell gun covers to, for those dusty ranges on windy days. Go to Double Tap once, and you'll start using one Link to comment Share on other sites More sharing options...

I had already added 1/2' rubber to the bottoms but like you suggested, I think the heavier ones from Taylor freelance ma be a better alternative.

Noximus03 Posted April 1, 2013 Share Posted April 1, 2013 I had to do some inside the grip work when I ran a ZEV. It pinched the bottom of the grip to the point my mags wouldn't drop away completely. Link to comment Share on other sites More sharing options...
blacklab2011 Posted April 1, 2013 Share Posted April 1, 2013 Don't over tighten the magwell may cause mags not to drop free. You may see some longtime glock shooters flip there wrists when dropping mags. Stems from old glock mags that did not drop free. All newer mags I have used with and without mag extensions drop free for me. Link to comment Share on other sites More sharing options...
DRock Posted April 2, 2013 Share Posted April 2, 2013 Just so you can double check here's a picture of a non-drop free mag on the left. The non-drop free aren't metal lined and tend to swell when loaded. You can see the metal lining on the magazine on the right thru the witness holes.

Tuflehundon Posted April 3, 2013 Share Posted April 3, 2013 Loosen the screw the holds the magwell in a 1/2 turn. Should allow the mags to drop free. I had the Zev magwell cause 1/2 of my mags to stick. Once I figured out that was the issue, I hit the inside the the magazine chute on the pistol with a few passes with a file and it took care of my issues.

gennaro Posted April 3, 2013 Share Posted April 3, 2013 It maybe best to just retire the gen1 mags, and pick-up some gen 3 or gen 4 mags, that way you don't have to worry , and enjoy shooting again. Link to comment Share on other sites More sharing options...
Tom C Posted April 3, 2013 Share Posted April 3, 2013 (edited) First, verify that the mags drop free without the magwell in place. This does 2 things: 1) tells you if it's something other than the magwell; 2) if they all drop free you have isolated the issue to the magwell and or it's installation. The actual history of Glock mags not being drop free is that it was not considered necessary for a Military firearm and, after all, this is why the first Glocks were made. It was not until Glock entered the USA and faced the demands of American shooters wanting drop free's that Glock added the linings (additional weight and minimized swelling).

mlmiller1 Posted April 3, 2013 Share Posted April 3, 2013 The original non drop free had a metal lining on 3 sides. Shaped like a U actually. Later mags have full metal lining that you can see through the witness holes. Easy to tell them apart. Link to comment Share on other sites More sharing options...

Dave Also note the rouned "U" shape cut out at the top of the mag is another indicator of a non-drop free design compared to the square cut out of a drop free.

Tyro Shooter Posted April 12, 2013 Share Posted April 12, 2013 it is important (with anyone's . . . not just ours) that you get the magwell insert installed correctly. we all design magwells to fit everybody's extended base pads. if your insert is not "Snug" in the back strap channel there is a tendency to over tighten the magwell on to the insert to "get it tight". this could be the cause of mag binding. For loose or wobbly inserts I apply a piece of "Self Adhesive Shim Stock" to the flat side of the insert. (I.E. Duct tape) so that it Snug and then install the magwell. do not over tighten the bottom bolt, as these tent to be small and thin and will stretch without too much force. if you break a bolt then you've gone a bit too far and now is a customer service issue. Oh and a non drop free mag on a early Gen frame can not converted to a drop free set up no matter how many times you call me, Link to comment Share on other sites More sharing options...
