I have the factory installed mag and bought two extra 5 round mags and one ten round mag and they all work perfectly. I haven't had to do any adjusting and I rotate them so that they all get the same amount of usage. My only problem with them is their price tag!

I've always made it a practice to buy multiple extra mags when I buy a firearm that uses them. These days, it's gotten a lot more expensive to do this.
