While wandering through Gander Mtn on lunch today I noticed that just got a shipment of 12 rnd mags for the 40's.

I picked up a couple and ran home to give them a try. The 10 rounders I have slide in and drop out with the greatest of ease. My brand new 12 rnd go in easy to a point and then take a fair amount of force to push all of the way into the handle. Then the mag release is real hard to push and when it does release, the mag doesn't drop, I have to pull it out.

Obviously there's some size and design differences but I wouldn't think it would it would be night and day like it appears to be.


Is this normal for the 12's as compared to the 10's????

With the 12 rd mags that came with my XD40, when fully loaded, are harder to load and realease (if still full) because the springs are new and very stiff. Probably just take a while for the springs to give a little

Leave the mag loaded and give it some time the spring will weaken.

Flip on the Outdoor Channel…..grab 24 rounds…..fix yourself a drink and then load the mags…..unload the mags……load the mags…..unload the mags……load the mags…..unload the mags……load the mags…..when your fingers get raw load them and leave them that way till tomorrow night and then start the procedure again. Trust me it works!

Or go to the range and shoot two or three hundred rounds. :wink:

I assume you mean when the mags are fully loaded. This is just the condition that they will be in when fully loaded and inserted into a gun with the slide fully forward. The top cartridge is pressed down by the slide. making the force required to insert go WAY up. Some people complained about this with the 10 rounders as well.

completely normal... This will partially go away with use.

Thanks for the info guys, the problem ends up being that the front lip of the mag is catching on the flat piece of metal above the mag catch. I noticed that after running the empty mag in and out several times that the 12rnd mag was getting different wear markings from the top of the front lip down to the catch hole in the mag. My other mags had thin light scratches from the mag catch coming in contact with the mag. The 12rnd had a wide scratch marks from the top to about half way to the catch hole. So I filed stripped the gun and ran the mag in and out and could see it not lining up.

I applied a little manual encouragement to the front lip of the mag and now it's running as smooth as the others loaded or empty.

Lesson learned here for me is exhaust all trouble shooting before posting.

Thanks again!

2fast don't be finding a problem is more than half the battle.
now the rest of us don't have to start from scratch if our new mags have problems.

just load 11 overnight and the 12th will go in fine. No need to kill your fingers
