Please help diagnose my Glock issues

[Pupulepeter]

Ejection observations scream weak ammo. New gun and weak ammo can cause problems due to stiff springs. Should clear up once things smooth out.

Sounds like a combination of weak ammo and slow slide speed due to the factory preservatives. Regardless of what the "Glock Armorer" said, completely clean and lube the pistol. Shoot full power 124gr Luger or even the hotter NATO spec ammo for break in.

First off, GREAT suggestions all around. Really high-quality feedback. You guys are great.

Second, I am shocked, shocked, that the one time I ever admit that something might be my fault, it turns out it likely isn't. I was actually hoping it was my technique because I figured that would be easier to adjust than having to send the pistol on the big brown truck.

I will check the two feed-lip spreads against each other (and my G26 mags) and see if Mag1 is unusually wide.

Still can't quite make up my mind to wipe the copper lube away, though.

[Chapped Hide]

Leave the copper lube there. Your Glock should function properly dry as a bone.

[Douglas Munro]

Hahahh HOT Ammo! 124gr is Slower than 115gr, mag is bad.

Break in for a new glock is one magazine, more like a mag break in.

Load them up and let them sit loaded until the next range visit.

buy a new mag and your good.

copper anti-seize is good, add a few drops of motor oil on the rails, shoot it till you run out of ammo, clean it once and a while and it will outlive all of us.

Other than the suggestions here, what direction does the brass fly when ejecting?

[static2126]

Thanks for the offer, static. I'm in Marin and shoot at Bullseye in San Rafael. If the issues continue after a more extensive break-in I just may take you up on that.

I'm also having my 1911 cerakoted so that will need some breaking in as well. Lots of lead to send down range.

Def I'm in Livermore.

Try hotter ammo. If you are concerned the springs are too tight (shoudln't be) lock the gun back in the safe for a while

Keep the copper grease on it will work fine.

Good question. Difficult to say, but I remember having shells land on my right forearm, about midway between the elbow and wrist, and a few of them thumped me right on the noggin.

I checked my ammo supply. The only hardball I have is Winchester White Box, which is also 115 grn. Is that stuff by any chance hotter than the federal? The 230 grain .45 drives my 1911 beautifully.

Winchester white box tends to be pretty tame ammo.

Go buy some 124 grain ammo

Another Glock armorer (LE/civy) here. There is no good reason to clean the factory copper lube from your gun unless you want to. The new guns that have come out in the last 2 years or so do in fact need a break-in period due to changes made to them. (Not Glocks smartest idea to change things but it seems Gaston is more worried about the bottom dollar these days that bullet proof reliability)
I suggest shooting hotter ammo 124/147 grain thru it for the next 200-300 rds. You can tinker with the mags, but I would get a hold of Glock and see if they will replace them.

I had similar issues with our Glock 34 when new. It would shoot most factory new ok but at about 500 rounds I started trying good quality reloads and struggled with weak or failed ejects and FTFs. Ultimately the fixes were a stronger recoil spring (I wanted a different design anyway) and stronger mag springs. We've got probably 5k thru it now, mostly reloads, and have had only a very, very few issues. Get yours broken in first and then and only then start your troubleshooting and do one thing at a time. If the change you make yields no improvement then go back a step before you get all messed up. Some guns take longer than others to figure out their particular issues. I have one other Glock that came new with a magazine release spring that fatigued and ruined one of the new mags after only a few outings. The part was cheap so I fixed it and the gun has been 100% ever since then. My third Glock was perfect out of the box but my overall experience with "Glock Perfection" has been one gun in three. I still like them all and when you look at what you get for the money I don't get too concerned about having to do a little troubleshooting. Of course I am not a LEO and am not carrying them so I can have this view whereas others may not.

Gen 3 gun, Gen 4 mags. Not that it should be an issue but try the Gen 3 mags that were intended to be used with the gun. That's my first thought. Second is new stiff springs and weak ammo but the mags are an obvious miss match that I'd try first.

[Stuttgart]

My guess is it's the followers that say "2183-1".

My 2183-1 followers work fine

Right out of the glock handbook... don't wipe off the copper antisieze. When I clean my 19, I do standard on the barrel, and pretty much just wipe the rest down. I pop the trigger group out to just run a couple q-tips through the frame because I hate seeing carbon build up. You shouldn't need to strip the slide after the first pre-firing cleaning until the round count gets up there.

I'd guess strong springs and weak loads. Sounds like it doesn't want to eject fast enough, nor really push the new round into battery. I'm going to say the redneck fix is leave the slide locked to the rear for a day and mags fully loaded. Should weaken the springs enough. Someone with more experience will likely disagree (not claiming to be any kind of expert here).

Maybe just because I'm poor and it's a glock, but all I use is tula/wolf in my 19. It has yet to have a malfunction after about 500 rounds. I shot 50 rounds of 9bple at about the 250rds mark for reliability test. I think the first 50 were perfecta brass. I don't intend to shoot anything but the cheapest ammo I can find through this gun (exception being testing HD anmo). I've done a 25 cent trigger job, put clp on it, and wrapped the grip in some tape to better fit my hand. Oh, and shoot it.
