Hi guys, I recently picked up 5 new springfield xdm 9 mags. I noticed they are not all pinned in the same place and they are all 19/10 mags.

On a couple when I load 10 rounds in they are a bastard to get the last round in even using the loader. Ive yet to shoot the pistol so I don't know how they will feed or if you can properly seat the mag on a closed action.

I know you can sand the followers on magpul mags (which I have done) but I didn't want to bugger up a $65 mag without checking here first.

Any suggestions will be greatly appreciated, a tutorial would be even better

Cheers

Fair enough, I've also heard of people snipping the mag spring as well. Is this advisable?

Try just doing the follower. You can always clip the spring later but you can't put coils back on it.

Edit: When you say they are all pinned in a different place, do you mean literally? Like different witness holes?

Yes when you compare the rivets there is almost an 1/8 of an inch difference between them. I by no means can load 11 rounds in the most spacious one but the tightest one is closer to 9 without a fight. Other than the 2 factory mags the other 5 came from two seperate vendors

Are they in the same hole though? My Glock 10/32 mags are all riveted in the 14th witness hole. Is that the case with yours?
 
I find a lot of pinned mags will only hold 9 rounds. or just barely 10 but can't seat the mag in a gun with the slide closed

try keeping them loaded to settle the springs first. you might have to do some filing of the followers after.....or just live with 9 rounds. a lot of times the rivet makes the follower impossible to remove, then you're just stuck with 9 rounds.

makes a great point for single stack guns like the 1911. why have a double stack gun with a big fat grip that you can barely squeeze 10 rounds into it?

+1. Clipping the spring may affect the mags ability to push the last few rounds up in time.

Because the gun is worth the girth, of course. Nothing against the 1911, but there are definite benefits to newer designs.
