Please help diagnose my Glock issues

[SB1964]

Think you nailed it with the weak ejection pattern. I've never liked the stock (squeaky) springs but I like Glocks. Find some 124 gn & break it in. I'd also suggest polishing the feedramp it's easy & it helps. Use some Mothers metal polish on a soft cloth.

I've never had a failure to feed or eject on a Glock, I've polished every feedramp I've seen.

I had the same issue with a g26. It was a bad batch of perfecta ammo from wally world. I know this because it caused my g19 to fail multiple times as well and it had never given me issues before. I opened a different box of the same ammo and the problem went away.

Sounds like it could be a couple things. First I would look at your grip and make sure you're not riding the slide with your thumbs. This (especially with seasoned prior 1911 shooters) can cause the above mentioned issues. Second I would look at your recoil spring. Glocks sometimes have overly tight recoil springs from the factory,too strong of a spring can cause weak ejections and feeding issues. Lastly, leave the copper grease, the grease helps the break in the pistol.

Rack your slide while you watch TV to help break in your recoil spring

All brand new guns have a break in period. The round count is typically 250-500.

Clean EVERYTHING - don't leave any factory grease on the gun - that's for storage not for function.

Most likely there is nothing wrong with the gun, it just needs to be broken in. The mag may also just need some exercise before it works 100% proper.

My 17 has no issues with 115gr target ammo.

The 'anti-seize stuff' he is referring to is not grease and is not supposed to be removed per the Glock manual.

i never shoot 115g 9mm, only 124 or 147. And never have problems with the five 9mm Glocks I own or the many other 9mm handguns I have.
Many will say it don't matter, but if you look into 9mm malfunctions you will see more failures with 115 then the heavier bullets.

Check your followers to determine what number is showing on the top, slide stop ledge. The latest should be marked with a "2", as there's now a 2183-2. Hopefully, this new follower will cure Glock's 10-round, 9mm mags' intermittent feeding problems. There haven't been any specific reports I've seen regarding this new follower, however.

Leave the anti-seize on the rails, but you can still oil/lubricate over it, as someone else suggested. I don't care what oil you use.

Ammo could be a concern. In general, the Glock doesn't need a break-in, but some of its recoil spring assemblies seem to have that need when new.

Ideally, if you can find somebody shooting with a known 100% functioning G17 with 17-round mags, that's what I'd like to see substituted in for a function test, along with its owner/shooter, for a 2nd opinion. Perhaps you could shoot their gun, too, to rule you out of the equation.

Same note with 115 for me

I also prefer 147 grains than 115

The copper anti-seize compound polishes the slide rails and slide rail cuts reducing the friction as the slide moves. This is part of the break in period.

I am surprised you are having trouble with a gen 3. I have gen 4 because I am a lefty. Both my G26 and G17 had issues that were finally fixed by replacing the recoil springs with stainless steel recoil springs. It was a problem only with my 9mm Glocks. My G 29 and G 30 were great out of the box.

On my G 26 the polymer frame was just slightly out of alignment. This caused the slide to not completely return to battery, but it return enough that the trigger reset and the next round was chambered. When the trigger was pulled, there would be a light striker hit on the primer and the round failed to fire. Now, if I pushed on the slide with my thumb before pulling the trigger it would fire.

By the time that problem was diagnosed, a month ago, it was too late to get it replaced as I cannot now get a Gen 4 DROSed to me in CA. The fix, replace the 16 lb factory spring with an 18 lb stainless steel spring. It runs flawlessly, with with the cheap Russian ammo.

For your situation, I would suspect the return spring. Fire some hot SD rounds through it or even some +P rounds through it. You can also store it for a while with the slide locked back or spend some time racking the slide.

The mag issues are mostly with the G 19, but it could be a factor. You can get some double stacked G17 mags that have been blocked to 10 rounds from Jestice Arms. http://jesticearms.com/index.php?rou...product_id=400

Finally, even a small amount of limp-wristing will have a large effect when shooting a new gun and using week ammo.

Brilliant suggestion to shoot someone elses, functioning, Glock. If it continues to function, it's not you. If it has issues, you need fixing.

[nedro]

You said FTF and I am assuming that it was failure to feed. Together with weak ejection, the recoil spring in your new Glock is stiff and needs to be broken in. Here are my suggestions it soften the spring.

1. Fully rack the slide every night. You can do this together with dry fire practice to work on your trigger press.
2. Keep shooting it.
3. Shoot it with hot ammo.

But if you don't want to waist both time and money waiting for it to finally shoot like it should've done from the beginning , get a 15 lbs spring and tungsten guide rod. Best bang for the buck of any mod you could do to a glock. Cheap and permanent insurance.
A stock 17 comes with a 17 lbs spring. The numbers are coincidence, not a designation.

[midvalleyshooter]

All these have been mentioned but just to sum them up:

1) Clean and lube the gun.
2) Load the mags and leave them in the safe a week +.
3) Lock the slide back on the gun and leave it in the safe a week +.
4) Get a variety of ammo including some hot NATO spec stuff.
5) On the next range visit take a friend with a Glock 17 use the suggestions above to troubleshoot the issue if it still exists after items 1 - 3 above. Another option is go to a a range the has a Glock 17 rental and try that out.
6) If you are then still having issues seek out a Glock Armorer locally to check out the pistol for you.
7) Finally if all the above fails call Glock.

After reading all the responses I have to laugh...

First there is nothing wrong with either you or the gun...It's your ammo.

Go get some good CCI Blazer Brass, Speer Lawman, or Winchester ammo in 124 or 147 grain and just shoot the gun.

As soon as I get any gun I go directly to the range and shoot at least 100 rounds...I have NEVER had an issue with a Glock handgun or magazine.
I have never had any Glock have any issues out of the box. They all shot accurately and reliably.

The only handgun I ever had issues with was a Kimber Pro Carry II. I sent it back and it shoots amazingly...it has since replaced my G19 as my nightstand gun.

Second time today I have to say B and S!
My 17 eats ANYTHING I feed it. If yours doesn't, you are doing something wrong or the gun is. Nothing more and nothing less!

9mm in 124 grain is NATO Standard.

I have no doubt your G17 eats everything, my G26, 19, 17, 34 eat everything too.
