Put about 200 rds. of 115 AND 124 gr. FMJ  and even some 115 gr. FMJ reloads thru a new Glock 19 with no problems.
Then tried some 124 gr. JHP (hydrashok) and had 1 FTF that later fed fine thru a Sig P239.  After cleaning the G19 at home, I tried to cycle other hydrashoks and win JHP and the round would not feed from the mag to the chamber.  The round was not even slightly angled up the feed ramp.  Not a mag problem as all 3 mags were disassembled and cleaned and still had FTF.  Dummy FMJ rounds feed good.
Tried polishing the feed ramp to smooth it out but not down to bare metal and mirror finish, but no help.
My other options is to shoot another 200 rds. of FMJ and then maybe try some hornady critical defense ammo.
Anyone else experienced or know of a similar situation and what else can be done to reliably feed JHP?   My G26 did not have this feed problem with JHP.

Is it every round in the magazine. Or just the last round? If it is what I think it is, it is a problem with the follower in the the 10 round only magazine. It is probably numbered 2183 and I have read online about lots of people having problems with them especially in the g19. I have a g17 and have only shot fmj so far. So I have to try some jhp next time I am at the range.

You should call glock and tell them about your problem and from what I read on many forums, they will just ship you the "9mm3" followers from the standard capacity magazines. Which should fix your situation.

Sometimes it's the 1st round sometimes the last. I now agree with the mag follower as cause after comparing the G26 gen 4 mag follower (1812-6) and the G19 gen 4 follower (2183-2).   Installed the 1812-6 in the G19 mag and no more feed issues with JHP when hand cycled  and will verify at the range.  The G19 follower is flat towards the chamber side and when pushed down tends to like nosedive instead of going down evenly like anti-tilt AR followers.  The G26 follower isn't flat and goes down evenly when depressed.
Mahalos for the tip on calling Glock to get the 9mm3 followers.  Also ordered some extra 1812-6 from Lone Wolf.

If you don't mind me asking. How did the conversation go with glock. Like what did they ask you. And did they give you any trouble trying to get the 9mm3 followers for free? I kinda want to get the 9mm3 followers also. But I have 12 magazines. So idk if they will give me that many.

I just registered the G19 and G26 online today and got a Glock ID number.  Their hours are Mon-Fri so no one on weekends.
I'll give you the 411 when I call tomorrow, may also send a e-mail to them to make sure they get it.
Funny that of probably thousands of G19 gen4 mags in use with the same followers, only a few get reported and 3 are mine.  Either I'm that guy when comes to Glocks or everybody only shooting FMJ since JHP is expensive.   

Talked to Glock  (770-432-1202) and they will send me free replacement followers.  No hassles.  I think that your pistol should have warranty registration with them since they asked for model and serial #.  I told them the problem and mentioned that my followers were 2183 on a 10 rd. mag.  They asked how many mags I had and took my info to send me different followers to try.
Give em a call, may have to wait a short while to connect to the tech guys after talking to the receptionist.
