Downloading USP 40 mags?

3093 Views 13 Replies 8 Participants Last post by  OfcrJosh462
I went shooting yesterday and brought my USP 40 LEM full size duty weapon. I had approx. 3 failure to feeds on the last round of my magazines.... the mags are the ones I carry on duty and have the Lone Wolf + mag springs installed. Now I'm wondering, should I download 1 round in all my duty mags to help stop this from happening? What would cause a last round ftf with the stronger mag springs? Dirty ammo? I know the gun was pristine when I started but we were shooting Tn Cartridge Co. reloads....

Any help fellas?

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?
