GXN prefix, approx 4K rounds through it. Factory stock except for night sights.
Here is the current problem:
I am getting BTF (Brass to Face) when using duty/SD type ammunition. There are no BTF issues when I use my standard range ammo.
BTF Ammunition: Speer GDHP 124 grain +P and standard pressure. Hornady Critical Duty 135 grain +P and standard pressure. Federal HST 124 and 147 standard pressure.
No BTF: Federal American Eagle 115, 124 and 147 grain. Federal RTP 115 grain standard pressure.
The BTF issue just started within the last few range trips. The recoil spring has maybe 2k on it, extractor is solid with no chips, ejector is good, depressor plunger is the correct setup without issues.
This gun has never exhibited BTF prior to this with any ammunition used.
First, Email glock. Yeah they will probably have you send it in, at least the slide. Maybe just replace the recoil spring assembly, extractor and spring if you want to. It will be the cost of shipping?.. Then it’s probably wear. Apex isn’t a wrong answer either.
Ok, I and apparently thousands more went thru this a few years back. MANY threads on here about it. Yes, my Gen 3 developed BTF after shooting it a lot too.
WHAT I DID: I cured the problem years & thousands of rounds ago, with a $12 ejector. Just stripped my pistol, the ejector number is 30274. Got it from Brownells.
Not a problem since.
Looked at it again- its 30274.
UPDATE: Just checked Brownells…the part is not there now. Lone Wolff has it the Gen 4 trigger housing with 30274 ejector for $7.99. Get that, slide out ejector and install into you Gen 3, its what I did.
I reached approximately 3000 rounds with my G19 Gen 4 when my ejection became erratic. Instead of replacing with another MIM extractor I went the Apex FRE + non-LCI spring loaded bearing route and all problems were eliminated.
While doing some reading on my issue, I came across a thread on TOS. There was a linked video with and ejector test for Glocks. Basically the newest ejector in the Gen 5 guns are the answer to erratic, BTF or weak ejection.
I’m trying to keep it simple where I don’t have to mix/match and replace parts. Not sure if that’s going to happen for me right now.
action steps: detail strip and clean the slide and all components therein. Replace RSA, extractor depressor plunger spring, trigger mechanism housing with ejector 30274 part, magazine springs. Glock relies upon rounds in the magazine to support the empty case during extraction. Test fire.
With that said, if you have only 4k rounds fired your gun hasn’t appreciably worn any parts unless they were defective. And if they were defective, I’d expect other issues.
Id spend $7.99 + $4.00 shipping on a new 30274 ejector, try it for a couple hundred rounds…before Is spend a nickle more. Is what I DID. Not one BTF in years & thousands of rounds. But, do as you wish.
Take with a grain a salt. I had brass to face develop after years of problem free shooting with my Gen4. I went with the Apex extractor and the stock plunger. I also used the 47021 ejector from the G19x which help bring bass ejection from my shoulder to lobbing it to 3 o’clock.
I bought a brand new G17 G3 years ago (TDX prefix) right when the new G4s were showing up. Mine did the same brass-to-face right outta the box. It was actually funny - I was wearing a ball cap and all of the spent brass was landing right on the bill.
Anyway, I lived in north Atlanta at the time so I took a couple of hours to drive it straight to Smyrna. It took them about 45 minutes but everything was fixed free of charge.
If I recall, the issue had something to do with the extractors on the new Gen 4 and late Gen 3s of that time frame. As others have said, a replacement of these relatively cheap parts may be the quickest and easier fix.
As the 19 gen 3 worked until about 4000 rounds. The ejector and extractor geometry is satisfactory.
When new and clean, the extractor holds the spent cartridge properly so that it consistently hit the ejector and had a good (no brass to face) pattern.
What I did with my G19 gen 3.
So what I would do is disassemble the slide. Clean out the channel with synthetic gun scrubber.
Clean and inspect parts. Be sure to clean the extractor at any shiny contact point. Also inspect for any chips where holding cartridge. If chipped I would
use another OEM extractor.
Extractor bearing extractor spring. If all look good reassemble.
I only use OEM.
On the frame inspect the ejector if ok then leave as is.
Reassemble then try it. If still btf then put in a new rsa. Try again if still btf.
Replace extractor spring and bearing.
Hopefully it should be working again as pre 4000 rounds. Premise is it worked before so clean OEM parts should work again.
