Thanks to you guys on this forum, I was able to quickly diagnose and solve a problem I experienced with my new XD40 Service on the first outing (12 round).

The second to the last round wouldn't chamber because of too much upward pressure from the last round in the mag. Someone suggested bending the lips inward a bit. I used a stone-slab as the base to press the lips in slightly so that they are now holding the brass a bit lower in the mags. I would guess that the lips are bent inward by 0.050" (maybe less). After about five minutes, the job was done, and every round cycles through the XD without a hitch.

I'm not complaining here - just a note for Springfield: The Croatian quality control should do this before it leaves their factory for the US.

Thanks again!

THANK YOU mcone, I have tried every trick I could think of and this problem would not go away. I love my XD9 but I had doubts as to the future of my XD40. I'll try bending the mag lips in a little, hope it works for me.

I didn't realize there were people having feeding trouble with their .40 high cap mags. I could only get 11 rounds in both of my mags because of the heavy spring pressure but they fed OK. The mags are currently sitting in my safe with 12 rounds (had to really push down on the first 11 to get number 12 in). I'm hoping if I let them sit for a week or so the springs may set or relax a little.

I'm not sure, I just bought two hi-caps from a nearby store, and I could get 12 in one of them, and only 11 in the other. Hopefully by tonight I will be able to squeeeeze in another one to make it 12.

Hey ajames, don, oldschool, and any other frequent hi-cap shooter....any problems with your hi-caps? And if so, does this "bending" method really work?

I'm the guy who started this thread, and it is not original with me. I got the idea from an earlier thread. Search for "lips" and you will find that at least one other guy has tried this. It worked for me. If you have the problem, I recommend that you try it. Or, better yet, please let me purchase your defective 12-round mags so that I can fix and use them myself. :D

So why did it work? Well, every next to the last round would FTF. I carefully examined the round in this position and it was being pushed too high - every time and in both magazines.

End result for my XD40: The rounds don't FTF now.

Here you go atkamano. I found a couple of quotes from other threads from guys that have a lot more experience with the XD than I:

Posted by KoG:
The other thing to check would be the mag lips to see if they have spread apart any.
Posted by adjamesp51:
Just squeeze you magazine lips closer about a 100th of an inch this will push the top round down. Cutting coils still means the top bullet is ridding to high. Try that before anything drastic.

Not sure if you care, but I have had no probs with my hi-cap 9mm mags.

I've got 3 of the hicap40's and not a problem with any of them; after a few weeks its much easier to get the 12th round in.

letting them sit is not enough you need to constantly load and unload them in addition to storing them loaded.

To the ounces that are having problems with their new 12 rounder, you need to use them even if you only can get 11 in. The more you rotate the bullets the more the spring will get a workout and the 12 will go in, in no time. You might want to get a speed loader to help work in the 12th in.

I want to update this report: My XD40 has yet to fail to feed since adjusting the lips inward over a month ago.

The 11th round is starting to go in with a lot of force, but I still have yet to get that 12th round in.

I just picked up an xd40 12 rounder on Saterday. I promptly went to range. The first time I tried to load it I could only get 10rds. in it. It shot ok with Win JHP 180grn. I tried again to get 12 in it. For #s 11&12 I pressed down real hard on the top casing with the tip of my thumb. Finally I got all 12 in there. Shot it 2 or 3 times that way and once more for the trip home. One more thing...I don't know who makes it,but don't buy any black mags. for the thing.Stick with the factory mags.
