Since the rounds are sticking in the mag, I would take a hard look at the feed lips. A fine polishing of the contact points may be the answer.
Mine looks similar. It seems to correct itself if I hold a firm grip.
See if it jams if you shoot it with one hand.

One other problem I had with a 4566 was a burr in the firing pin hole. The burr would catch about one round out of five, preventing it from sliding all the way up the bolt face, thus, preventing its entering the feed ramp.
Look for a fresh scratch on the head of the cartridge of those rounds that fail to feed. I removed the burr from my gun by spinning a 1/8" drill bit in the firing pin WITH MY FINGERS.
Dino1 and Robotech are on the right track. The feed ramp should be polished and concaved from S&W. Yours looks flat, and there is a "skid mark" up the middle. Not right! DIY, or better, send it back to Smith. It looks like an unfinished barrel.
Practiced with my Shield 40 and a box of WWB yesterday without failure... as always.
Contact Smith. DIY 'improvement' will likely void the warranty
I contacted Smith about my issue and after a lengthy conversation they asked me to send them back the Shield for evaluation. I asked the guy on the phone if he's heard of my issue and he said yes but only a very small percent of Shields.
I concur.
Having shot exactly 1,000 rounds through the Shield, I've experienced a failure to chamber the next round or a jam 10 times - so a 1% failure rate which is unacceptable for a CCW. I contacted Smith about my issue and after a lengthy conversation they asked me to send them back the Shield for evaluation. I asked the guy on the phone if he's heard of my issue and he said yes but only a very small percent of Shields.
I'm hoping they'll polish the feed ramp for me and correct anything else they see wrong with the gun.
As a side note, I've noticed those reporting this issue with their Shield all have the 40 cal version. Anyone experiencing this issue with their 9mm?
I shipped my Shield 40 out to S&W on 2/21/14 and received it back on 3/10/14. Looks like they had it for 9 business days, so that's rather quick.
They gave me an extra 40 cal 6-round magazine along with a note explaining the repair -
"Polished feed ramp, replaced guide rod, adjusted trigger pull, function tested - no issues"
I will take it to the range after Wednesday of this week to see how it performs.
Nomadic Vagabond, what were your results at the range since you've received it back from S&W?
So, I just got back from the range....
HOWEVER... I also fed my Shield 40 my carry ammo, which is 165gr Hornady Critical Defense. I only brought 14 rounds to the range and loaded up 2 mags worth (6+1). I had 2 Failure-to-Feed in the middle of both mags. There was ammo still remaining in the mag with the slide locked back. Same damn issue!!!!!
IT GETS WORSE... I checked out the spent casings on my WWB FMJ ammo and those were fine, BUT, the Hornady Critical Defense casings were BULGING at the bottom!!! This is my carry ammo so I'm really upset this happened....
Actually I shipped mine out and received it back on the exact same dates, Shipped on 2/21, S&W received it on 2/24 and and received from them on 3/10. They did not give me a free mag probably because i sent them all 5 of my mags in with the gun, maybe they figured I had enough already. The repair document states
"Performed Service: Evaluate / Repair - Replace Barrel/Extractor/Function Test"
So I take it out to the range today to fire a few hundred rounds through it to see how it performs. Same damn issue! after 5 Fail to Feed out of 250 rounds (and one stove pipe, slide caught the spent casing as it was feeding the next round) I left the range. Same deal as before, Bullet nose down, not touching feed ramp, happens with any of my 5 mags and 2 and a half boxes of WWB ammo. I'm planning to call S&W to see if they want me to send it back... again.

Shield.40 Still Fails to Feed After Repair2

I will say that it did shoot about 100 rounds before my first fail to feed today. Even before i sent it in for repair, it did have a 70 round streak without failure, and at other times I've had two fail to feed in the same mag... it's very inconsistent. I would like to see it eat at least 500 rounds flawlessly before i consider it truly fixed and reliable. I would hope that's not asking too much? My M&P 40c has a few thousand rounds through it and have never had one issue (that wasn't defective ammo related). My carry ammo is also Hornady Critical Defense but I have yet to shoot any through the gun... I'll have to test those as well.
I'm waiting to install a bunch of parts that I already purchased (Apex DCAEK, AET, Sights, Talon Grip) so I'm kind of committed... which I'm fine with (as long as it gets fixed or replaced in the end) since i really like the Shield 40, hell that's why I bought it. But I'm not interested in the 9mm version at all.
I bought a new .40 Shield that did the exact same thing twice within 100 rds of 165g PMC fmj. I bought it on Monday and traded it back in on the following Wednesday for a Glock 36.
