So first, the arty shot to show I've got class:

yea, that's not so good but what do you want, it's a glock sitting on some empties swept up in a pile.

Just hit the 19k rounds today, and over the history I've:

- 10k-ish replaced mag springs with Wolff +10% and polished mag body internals
- 11,507 new recoil spring
- 15k-ish cleaned mags and polished mag body internals
- 15,500 new trigger spring, new firing pin spring, new firing pin cups, put OEM slide stop back (after market one was toast)
- 17k-ish new extractor spring

I'll start keeping better notes on when I replace parts, haven't been putting that in the spreadsheet just writing the approx round count on the bag that holds the old parts.

With 95% of the ammo being steel case Russian stuff, I've found that the insides of the mags get roughed up a lot and rounds start to bind after a while. Usually the recoil of the gun keeps them knocked loose and feeding but with the original springs getting so weak after 10k+ it was causing issues. Now when it feel them binding I just clean the mags, about every 5k rounds. The 10 mags I use in the gun all the time actually have more rounds through them than the pistol itself because they get used in other glocks and my Ruger carbine, however the other guns and the carbine don't have but a few thousand through them in total.

I had some FETs after the first batch of spring replacements, but I had forgotten to order the extractor spring. Once that one was replaced the FTEs were reduced to just 2, and both were with the same batch of aluminum case ammo. No drama in the last 1500 so I'm calling it fixed.

Wear doesn't look all that bad, don't see any cracks or anything anywhere. Just needs a cleaning more than anything.

Oh wait, I forgot I used those mags in my Sub2k too, so they've got another 1055 rounds on them. Still under 22k though.
 
Great post Jayne! You are tempting me to get onena these long slides. I like your round count reports. Have you ever read Chuck Taylors 30 year 300,000 round test of the G17?? Amazing stuff!
 
I want to hear more about the classes your taking with that grock.

Meh, I don't know that they're helping. I mean, I feel faster and more accurate but my match scores don't reflect that. It's possible I've just hit the max of my ability. Sorta like my draw speed, it's not getting better... we can't all be really good at stuff.
 
Is it my eyes? The firing pin hole looks beat up.
Thanks, I recently got a G34.

Agreed. Side by side with my G26 that has 1/10th the number of rounds through it there is quite a difference. Now, has it been like that the whole time? No data.

Are you running very hot loads?
I'd like to see a pic of your grip, I haven't found a grip that doesn't come in contact with the extended and raised slide release. :confused:

It's all Russian steel, and I know that some are warmer than others but it's not a steady diet of +P or funky handloads.

Just for grins I emailed Glock. The images of cracked breech faces are out there, but I'm wondering if those are early failures from defects or long term use failures.

That's why I replaced it originally, I was always touching it and keeping the slide from locking. Now I just move my non-support hand thumb to the left of my support hand thumb rather than directly on top of it in the standard 'thumbs forward' grip. Actually makes it easier to grip for me since I don't have to force my hand around the gun to get the thumb in the same spot it sits on a 1911 (easier with it's single stack grip) and I don't hit even the extended slide release anymore. win-win.

A pic would help, I’m not picturing it.
Thx!

Not only did I hit a wall, I got worse. But I got past that by quitting.

I have a feeling that you'd do just fine to partner with. I can tell you that from a 72 year perspective things start to dwindle. You can keep them honed, but they are forever sliding away. Everybody, whether Bob Mundon or you and me, reach their own personal ceiling. With the dedication to improvement you have shown, you can ride in my truck anytime.
 
My G34 does not get any love. I put a Burris FastFire MOS on it and it still does not get shot. I bought a big stick mag for it and havent shot that either. Keep meaning to get up to Oxford and shoot steel challenge matches. Now Im down with ortho surgery recovery. Good to know it will take a lickin and keep on tickin.

Try their ProAm falling steel match. Fun with a red dot!

I'm generally pretty safe, several people here have shot matches with me and survived to tell the tale. Those who haven't survived.... probably hang out on that other forum and vote Democrat now.

How frequently do you clean it? That is some impressive carbon buildup around the striker safety plunger.

Gets a brush run through the barrel (the nylon brush that comes with it) every 300-500 along with a cursory cleaning of knocking the big chunks of crud out. I do keep it properly lubed, this isn't some torture test to see how long it goes before it dies due to lack of lubrication.

That sort of buildup can happen pretty quickly with some of the Russian ammo.... although the spreadsheet says that 637 rounds worth of crud. I cleaned it right before class and haven't since, so I will clean it up before the match tonight. It's just powder residue, it comes out easily.
 
Yea, holes magically appear in BMW's, blue barrels and door frames.

Hey, that was because the optic was falling off! I'll admit to the pesky BMW and that barrel, but I never hit the door frame. I had pulled the optic by that stage.
