re: My new Glock 19 jams a bunch

Probably Mag related. See if you can borrow someone elses mag. But could be something else. The advice to clean (no oil around lower trigger assembly and very little oil on slide rails) is where I'd start.
Put some downrange and if problem happens again Glock would be where I'd take it.

You have an 1/8" gap between the grip and the bottom of the mag, when the mag is seated. Here is a pic of mine, same gun factory mag:
Much smaller gap.

It's about like that.Just doesn't seat all the way up in the grip like my cousins Sub Compact 9mm Glock does. He said it didn't feel or look right.

Hey MJ2. Good to see you in these parts. 
1. Check out my YouTube channel, Bigapple0828. I have a video called "proper technique and grip" (or something along those lines). It will tell you the best way to grip your pistol to make sure you are not causing a malfunction by limp wristing. This is most commonly attributable to a "teacup" or "cup-and-saucer" type grip.
2. If the thing is that new, call Glock. They will know best since it's their gun. I don't own any Glocks so have never dealt with them but I hear their customer support is very good.
3. ANY GUN can malfunction. There are lemons in every batch of something made 1000s of times. For a gun as godly as a Glock to jam is not some stroke of a miracle.
4. The magazines fitting a bit loose is not surprising. Glocks are designed with loose tolerances on purpose. The mag base plate also may not sit perfectly flush with the bottom of the grip (*especially if you're using G17 mags). This is all normal. Then again, I don't own any so I could be wrong.
5. The way modern polymer semi auto pistols are designed these days, adding lubrication is almost entirely unnecessary. My S&W M&P, Ruger SR9c, and Kahr CM9, all of which are polymer autos, rarely see oil of any kind. I clean them with CLP and whatever trace amounts of oil stays on the metal is usually all it gets. If your gun NEEDS oil to function SOMETIMES, there is a problem. Also make sure you don't overlube your gun. This can attract powder residue and cause issues.
6. Do as others suggest and shoot it a couple 100 more times. But for a Glock to have a break-in period is somewhat farfetched. Although I have heard the gen 4s have had a lot of teething issues.
Best of luck. Let us know the outcome.

Is the spring in correctly(not backwards)?
Probably a pic or two of the assembled slide off of the main portion of the gun might help.
Out of all of my guns, I have only had one that had FTE problems when new. The M&P Shield was that gun, and it only FTE'd 3 rounds out of 200. Those were all on the first two magazines I put through it, and no problems after that

That's not uncommon with a gun that has an action that short. Those small subcompact guns have to have a very stiff recoil spring. This is why they have a possible "break-in" period. But the G19 does not necessarily fit this category.

Glocks are the most susceptible to limp wristing. If you watch Military Arms Channel on YouTube, he is unable to replicate a limp wristing issue using a Sig P226, which has a metal frame. But he is able to get his Glock to jam by limp wristing.
The teacup grip prevents the pistol from recoiling against a hard surface, which is exactly what it HAS to do to function properly. If that rearward motion of the slide turns into rotational motion (i.e. if you limp wrist) then the slide may not go all the way rearward. It needs to do this to strip the next round from the magazine while ejecting the spent case.
Let me know if you have any other issues.

That's what makes me think it's that specific gun. Because the smaller a gun is, the more likely it is to be very recoil-sensitive when it comes to reliability.
EDIT: But you should still use the proper grip. If you are in a dangerous situation, your body will gravitate to things that are automatic. If you have it built in your mind to grip a gun the wrong way, it could fail at the worst possible time.

Glocks are almost Fool proof when putting them back together.
I say almost because someone will come up with an unusual example, I'm sure.

I shot a few different types of ammo out of the Shield the other day, and lastly went through a year old box of WWB JHPs. That was the worst shooting I have ever done in my life....to the point of pissing me off.
I was shooting the center out of a 0.5" bullseye at 25ft every time with Herter's brass in the PPQ. Switched to the Shield and the WWB, and couldn't even get 6" groups at 10ft. Got angry and started throwing the bullets at the target more accurately than I was shooting.
I've never experienced something like that, but could only attribute it to the ammo. Very odd

Or, honestly a Sig, H&K or S&W M&P series - for that matter - by design - the last thing they want are reports of somebody have a brand new gun fail to function and get a law enforcement officer or good guy citizen killed.
I took a brand new G23 to the range a couple of years back - CLP (all Glock uses at the factory is CLP) at the metal contact points (I did field strip and thoroughly clean everything with CLP prior to going to the range) - and put 100 rounds of ball and ~30 of my carry ammo through it - and zero issues. That was probably only my second or third experience firing a Glock (although, IIRC I fired a G22 that same day) and I was impressed with how little drama there was in breaking in a new gun. As a Sig guy, I'm relatively spoiled, and unaccustomed to FTF/FTE in a pistol.
(Other than the aftermarket grip issue I mentioned earlier, with my old West German P220 - never should have sold it BTW
- I've never had a malfunction with a half dozen Sig pistols over the years.)

Could you repeat that? Everytime I tried to read your statement the fact that the 1911 has been in continuous combat service for over 100 years kept interrupting my concentration.

Disassemble your gun and check to see if your ejector has 30274 printed on it. This is supposed to be the "good" ejector. I believe the faulty ejector number is 336. The late Gen 3 models had ejection problems. Also check your recoil spring to see if it has 0-3-4 printed on it. This is supposed to be the "good" spring. When the Gen 4 Glocks first came out, Glock was still producing the Gen 3 and Gen 4 Glock 19s at the same time. Glock was installing the early Gen 4 Glock 19s with faulty ejectors as well as the late Gen 3s that they were producing at the same time.
The crazy thing is all Glock 23 Gen 4s are reported to run flawlessly. I have about 800 rounds through my Glock 23 with zero jams. Hope this helps....

I do agree that is very odd. I would've gotten frustrated too.

Exactly. For a tiny gun to have some teething malfunctions (like my Kahr not locking back on the first mag I ever fired through it) is pretty normal. But for a larger handgun to have issues that early isn't normal.

Once I got my CZ 452 sighted in at 25yards, I shot a 10 shot group of cheap remy ammo through the same hole shooting off of my gf's purse, so it wasn't all bad that day
MJ2, I still think a pic or three might help diagnose it a little better. It would be like me trying to describe what type of squeak is coming from my engine compartment over the phone

Make certain you have the spring loaded correctly. There is a seat for the spring on a Glock and there is another ridge slightly above the seat. The spring will sit on the 2nd seat and the weapon will still fire but it will not cycle rounds correctly. I had this happen before and it is frustrating. If this is not the issue make certain you are holding the pistol as high as you can. I often see people hold auto pistols too low and this causes misfeeds.
