What website are you downloading these mags from? I'm gonna get me a couple!! lol :20000000: I've tried this too and it doesn't seem to help. I would suggest changing mag springs. Go with wolf springs they always seem to help

That's weird; when I was issued the weapon I upgraded all the springs to the 10+. I've got a couple more, I'll try swapping it out again.

What kind of ammo are you running? Are your mags nice and clean and do you clean them often? I'd try changing ammo first. Is your feed ramp nice and clean?Do you have this trouble with any other pistols? as someone else stated it could be you letting your wrist break too much the .40 is usually a snappy round and I've had a few friends have the problem with their wrists.

ETA: here's a link to some springs I was bored and found some for you. http://www.gunsprings.com/SemiAuto/HecklerKochNF.html#USP

Also is that quote in your sig line from when the SWAT team shot that man down in Florida for killing an officer and his K-9?
