Call them and see if you can send them the pics you just posted. Except this time, ask if they will just send you a new barrel since you've already been weeks without your gun.
Updated w/ pictures New Shield chamber problem?

The proof will be in the shooting. However, before you shoot it, could you post a pic of your barrel with a round in the chamber? A view like this would tell us a lot:

Wasn't this the Glock issue
Wasn't that the problem with early Glocks. i.e. case head bulging/failure from a feed ramp cut too deep? Glock was compelled to change their design. Too bad S&W is repeating a mistake that was fixed by a competitor.

So what ever happened with this? Smith modified my barrel too because I was getting light strikes and ftf's with winchester white box. Premium ammo. and blazer worked fine, although on occasion, the primer would still indicate a light strike.
I haven't had issues with the modified chamber, but it appears to be not fully supported near the feed ramp, like in the picture above, but not quite as severe.
Should I request a new barrel?

IMO what we are seeing is a result of the compact size of the Shield. Shrink a semi auto down to near pocket pistol dimensions and you end up facing a choice between reliability or feed ramp intrusion into the chamber.
The problem is that as you reduce the barrel length you also reduce the length of the recoil assembly. In addition it's also very typical for the Slide Overrun to be reduced in an effort to keep the recoil assembly as long as possible. So, what has to be done to provide reliable feed when the Slide Overrun is reduced. You can either move the feed ramp towards the the front of the chamber or you can make the feed ramp steeper. Guess what happens when you make a feed ramp steeper? You create a semi that is EXTREMELY picky about the shape of the bullet and has a strong tendency to jamb.
So, what's to be done about this. It's rather obvious that cases used in the Shield aren't a good choice for reloading. If that bothers you, Tough. There are plenty of other semi's on that market that feature fully supported chambers.
It's also rather obvious that the Shield wasn't designed to be a Range Gun. One aspect of the shortened recoil assembly in the Shield is that I expect the springs will require replacement at rather frequent intervals, probably every 750 rounds fired. I would recommend those who purchased a Shield for Defense shoot it just enough to maintain proficiency with it and no more than that. You'll also want to keep a log of the rounds fired so you know exactly when to replace recoil and magazine springs.

My converted Shield barrels appear to be perfectly even on spacing. .40 on left and 9mm on right.
As for the recoil spring, we're not even going to talk about how many thousands of rounds I have through mine. But you could say i have more than plenty of rounds through it. And it still performs top knotch.

im curious if smith and wesson has put a life expectancy on these pistols like kel tec did thiers (6k or more rounds).
while it may be designed with concealed carry in mind, the quality and materials say it can take range use fine, imo.
my P95 has polymer guide "rails" and ive read numerous reports of people having 5k+ rounds through theirs with no issues or excessive wear on them.
this is what mine looks like...its fired and spit out every round ive put through it so far. havnt checked the empties though and i did feed it a few +p...
