A couple of weeks ago my XDm started jamming on the last round of each magazine. Springfield said it was the magazine, probably the spring inside it. So, they e-mailed a shipping lable that I printed out and sent the mags back to them. I did get the new magazines yesterday and plan to try them out very soon. However, I am only loading them up with 12 rounds instead of 16. Something funny is going on with those springs - anybody else had an issue like that (or even with a different type of semi-auto?) Later, B
Good luck with that. Same here...for the first thousand rounds or so. Then it started jamming and I lost a lot of confidence in semi-autos. SA replaced the magazines for free, but I'm only loading up to 12 rounds. I shot the gun last night for the first time with the new magazines and I can shoot that gun very well, quickly, accurately...it is an awesome cartridge (.40 S&W). However, every time I pull the trigger I wonder if it is going to fire, and I can't stand that with respect to a defense weapon.
I have purchased an airlite .38 +P revolver and I shot it last night. It's not accurate and kicks like a mule, but every time I pulled the trigger it fired, and based on my experience with revolvers, I am fairly confident that it will fire every time. I would rather have 5 shots that I know are going to fire than 16 that may fire.
Sorry to be negative, but it will take a long time before I have any confidence in another semi-auto. I went to the range last night with a bunch of friends, and I shared the lane with a buddy who has a CZ - it was jamming too. For home defense, I bought a Mossberg 500 12-gage shotgun, and for carry I have the .38. The .40 XDm, for me, is now a novelty that will be fun to plink with at the range, but I would have a hard time trusting my life to it. Doesn't matter what anybody else thinks, its what I think that matters, and I know this gun jams. Good luck with yours.
I do know that disassembly can change the twist of the mag spring and it does have to have a twist to it to work properly. I have not had any trouble from mine (4) and I have about 1,200 rounds thru mine.

DWARREN,
Tell me more about this. Can you explain the twist you're talking about? I did disassemble the XDm magazines to clean them and put them back together...right after that is when they started jamming and I just figured I would never take these new magazines apart for fear I did something wrong last time. Is there a trick that I'm missing on how it goes back together.
What ammo are you shooting? . . . steel casings are a no-no . . .
If you name some type of ammo, I've probably shot it. Mostly WWB. No steel casings. The gun is working now with new mags, but I won't load it to capacity again.

Steel casings won't be the cause for the last round to jam, they would cause every round to jam (if the gun was having extraction issues).
Steel casing's aren't a no-no, they are just rough on extractors. As long as you're prepared to replace extractors at roughly 3000-4000 rounds, rather than 10,000 rounds, then you have nothing to worry about.
The springs in the mags are twisted from top to bottom, the top does not align with the bottom. If the twist is not correct the spring binds on itself and causes loading and feed problems.
Do not ask how I found this out.

Alright then...the magazine problems never happened until sometime AFTER I opened it and cleaned it. I recall when I put it back together wondering how it went...so if I put the spring in 180 degrees off from where it was supposed to be (i.e., backward) could that have caused my feed problem? Thanks, B
XDM 40, got one of the first ones to hit Nebraska, I have never ever had a feed issue over 5000 rounds through it, I shoot mostly 180grain Rem UMC which are reloads.
The problem is not front to back but from top to bottom. If you look from the top of the spring down along it to the bottom you will see that it is twisted, top does not align with bottom. If the twist is not right it will cause the spring to bind and cause loading/feeding problems.
Not disassembling the mags seems to be the cure, mine were not dirty even after appoximately 400 rounds of lead bullets and 1,000 rounds of jacketed.
Putting the spring in with the high part of the top to the front of the mag and the bottom of the spring is fairly hard to insert since it will be twisted to one side, twist it so it will go in and put on the plate then cover.
Do not ever twist the mag spring or try to elongate it in any way when outside the mag as this will cause problems.

I'm convinced I screwed up the magazines when I took them apart. The new ones have worked perfectly (just like the original ones did before I took them apart). I shot Georgia Arms loads through it today and it fired perfectly every time. I still think I may shy away from Blazer Brass in a semi-auto, but I'm willing to shoot anything else. I like having a gun that works.
By the way, I've been going to a fairly new range in Maryville, Tennessee called Gunney's. I went there again today. Lots of fun and the folks there are very nice (unlike some other local ranges).
DWarren - thanks for all the info. I feel better knowing there's a logical reason for my gun issues. I don't think I'll ever clean these magazines again. Thanks, B

It keeps jamming even after you started loading less ammo in it?? That’s weird!
this happenes now and again to magazines from all manufacturers . springs wear out at differnt rates sometimes you just get one that wasnt as well made as it should be .
Anyone having problems with the ammunition inside the magazines rattling? I have tried different loads from 1 all the way to full capacity 19. Rattling seems to start around 8-9 rounds. Both magazines are brand new from the box, never even been fired. Any suggestions are appreciated.
its just the way the rounds ( im guessing you are using JHP) sit against each other. it has not effected feeding yet as far as i have seen in thousands of rounds.
Maybe it's the ammo . . .
