Just got my Service XD40 last week and have noticed something. It came with 2 12 round magazines and if I load them to full capacity they are way harder to push in and also the eject button is REALLY REALLY hard to push to get the magazine out way too hard to do with just your thumb. If you take one round out and leave them at 10 or 11 rounds they don't have this problem. Great forum btw everything on here has been very informative.
