Generally speaking, the problem is more likely to be you than the gun or its magazines.
If you are not holding your pistol very firmly, with strong arms, some of the recoil impulse the gun needs for operation is being absorbed by the movement of the gun in your hands, or the movement of your arms.
This problem showed up when using PMC ammunition, perhaps because it was loaded to lower velocity than was the Federal stuff that worked for you.
Try holding tighter, and with stiffer arms. My coach always called it "bearing down."
