Just picked up LDA HI CAP .45. The mag that comes with it is supposed to hold 14 rounds. At first I could only get 9 in it. I bought a used Mag that was once a 10 rounder, someone had pulled out the block and it now holds 16

. Anyways I pulled apart both mags. The new one has a long heavy spring it. I cut 1 coil off and put it back together and managed to squeeze in 11 rounds. Pulled it apart again, lopped off another coil and only managed 12. Now Im pissed. I really dont want to cut the spring anymore. Should I call Para and get a new spring or continue cutting?
Btw both mags feed flawlessly. And the gun sure is a sweet shooter.
I wouldn't have cut the spring at all. It sounds like a good stiff spring that just needs to be broken in. Load it up and put int he gun and let it sit a couple days then unload it and repeat until it will hold the full capacity.
If your mag steel sides go all the way down and the base plate locks onto the side of the steel body, then you have a high cap mag. If the steel sidewalls are shorter, and there is a plastic block that attaches to the bottom of the plastic block and then the mag base attaches to the plastic block, then it's a 10 count mag.
Yes, you can clip the center tab out of the top of the plastic block on the 10 rounds to get a few extra rounds in the mags on some models, but the 10 round will never load to high cap standards. As for carving the center out of the plastic block to allow spring/rounds to go all the way to the bottom of the mag (touch the base plate, the rounds jam up as they reach the top lips of the plastic block.
As for 14-45 mags, ACT-mag makes a great after market unit, then there is Mec-gar mags that will hold one round less, and has a steel bottom plate instead of the plastic type of the act/factory units, then there is factory mags for twice the price of the two above units.
my new mags did the same thing.
load them up and let sit for 1 month. then load and unload (or shoot it) until your hand gets tired. eventually you will get all 14 in there.
the factory mags are all that way.
