So I got a new Glock 19 gen 5. Every once in a while it won't chamber a round when I insert a mag with the slide locked back. This has happened two or three times. I have shot the gun a couple of hundred times and it has performed perfectly. I think the reason why it won't chamber a round is that I haven't inserted the mag in all the way or perhaps I am not pulling the slide hard enough back. When I am consciously inserting the mag with enough force I never have any problems and obviously pulling the slide back hard. So can you let me know if this is probably the case. I haven't had this problem with at glock 19 gen 3 and glock 26 gen 4. Perhaps a gen 5 is a little more sensitive.

Operating the gun requires focus and intensity. Sloppy operation will lead to sloppy function.

Yes mag needs to be properly locked in to work.
Yes the slide needs to be cycled properly, that means pulled back fully and let go-- not EASED or interfered with going back...or use the slide release lever.

If neither of the above apply, then your ammo may be non-standard, but the above are the 2 main causes of your symptoms.

I've had first round loading problems ONLY when using a 10-round G19 mag. My first round loading problem occurred in Gens 3, 4, & 5, not just Gen5.

I understand Glock now has a newer 2183-2 follower, but I've not yet tried it as a 10-round G19 mag is only a range mag for me (or ban location, should I decide to carry my G19Gen5 in such a place).

EDIT 8/28/19: I do have the 2183-2 follower (I thought I only had the old/original follower) and did a brief test. JHP rounds (Speed Gold Dot and a Federal HST) both would not chamber from slide lock back, if there was only one round in the mag. The rounds fed fine if there were 2 or 10 rounds loaded in the mag. I suppose if, for some reason, I was down to just one round, I'd have to chamber-load that last round (probably unlikely, but suppose it could happen).

Otherwise, Post#4 seems to have covered the issues. OP didn't mention what ammo or mags. Also, Glock's parts list indicates the latest regular 15-round mag should have a #6 follower now. The latest mag follower is usually a good idea to use.

Either of the two options you mentioned could cause the problem. Make sure the mag is firmly seated every time and make sure you pull the slide all the way back and let it fly forward, and see if the problem persists. You might pick up some dummy rounds to test at home to see if those fixes solve your problem.

My 19 gen 5, serial BGFW... hasnt had any trouble. I've only used the original mags and a couple of Magpul 17 round mags, with HST, Fiochhi, Federal, Blazer, Magtech and S&B ammo (all brass FMJ except the HST).

My early gen 4 19 does exactly the same. A bit of a slap to the magazines bottom fixes it every time. I've ruled out ammo and magazine as the cause, guess my gun's just a bit kinky.

That and the fact that you aren't having problems during firing makes me think it is your error. It is not a delicate instrument. It doesn't need to be abused, but you can do things firmly without hurting it. Put the mag in solidly. Rack the slide completely and let it go forward. Nothing you can do with your hands is more forceful that the stresses it gets when shooting. Don't baby the pistol and I bet you come out fine.

Dang... I remember the 9mm3 follower being all the rage...

Hi guys the ammo I am using is winchester nato 9 mm fmj 124 grain so it is not reload ammo. I just wanted to confirm it was my technique and it seems like it is. I have 200 rounds through it and it has been flawless. This gun though does seem more sensitive than the other Glocks I have since they have not had any problems chambering rounds. Every gun is unique and they have their quirks. Obviously that is why you need to shoot a gun to get familiar with it :).
