Glock 27 Breakage: Repair Suggestions?

[Duces Tecum]

My G-27 failed after 19,519 dry fires and I’m soliciting repair suggestions. The slide cannot be moved rearwards.

The gun disassembles completely in the normal manner except that the barrel does not remove from the slide. The barrel chamber end of the barrel does not drop enough to clear the ejection port. The tip of the firing pin is unbroken and the extractor and ejector appear to be fine.

Any ideas?

I am going to take a guess that the breachface has cracked and is protruding into the chamber.

My next step would be to call Glock.

This is my guess as well. Give them a call - they have replaced slides for this issue before.

[LOKNLOD]

Agreed on the probability of the breech face crackage. Depending on the severity of the cracking, you might be able to take an appropriately sized dowel and press it into the barrel via the muzzle and "pop" it back enough to remove the barrel.

Going to go ahead and apologize for not being helpful.

But am I alone in being stunned in that someone keeps that detailed count of dry fire pulls?!!

[Duces Tecum]

Thanks, guys. It turns out that is exactly what the problem is: breechface failure. I'd never seen (and certainly not experienced) one before, and I'm grateful for your (plural) comments.

Miller_Man, it's not quite as anal as it might at first appear. I'm doing Claude Werner's splendid 1000 day dryfire challange with a dedicated gun, shooting 50 dryfires a day. This happened 19 dryfires into day 390.

Once again, thanks to everybody.

I was picturing you sitting there with one of these things in your off hand.

So, knowing nothing at all about Glocks, would that many live rounds have likely had the same issue? Would the absence/presence of snap caps change anything?

[miller_man]

Ahhh, ok :o

Any time. Let us know how it goes - they should have a new one out to you in the mail ASAP.

BB, I got a great laugh out of that!

Thanks, Nephrology.

Well, I have significantly over 20K live rounds through G-23 and there is no sign of breechface failure. From what I've been able to determine, live fire pushes the breechface backwards, where it belongs. Somehow, and I'm not entirely clear how, dryfire pushes the breechface forwards, where it shouldn't be. Others will certainly have a better explanation.

I've never been fond of snap caps, especially during repetitive fire practice. Press the trigger. Rack the slide. Find the snap cap. Pick up the snap cap. Chamber the snap cap. Press the trigger. Rack . . .

Ah, right, you've got to rack the slide between dry fires. I always forget that in these conversations.

On Glocks at least you can retract the slide far enough to reset the trigger without fully extracting the snap cap.

[warpedcamshaft]

I dryfire with a snap cap and only cycle the action enough to reset the striker. You don't have to pull back very far to get it to that point. I've heard of about 5 or 6 breach face failures on heavily dry-fired Glock pistols (including Todd's) and am hoping a snap cap helps long term. In reality, it may not help, but it makes me feel better about myself... and isn't that what really counts? :o

Update:

Following the suggestions above, I returned my barrel / slide (could not separate them) by Priority Mail to Glock on 28 Sep 2015. It was delivered on 30 Sep 2015. Russell Murphy, Glock pistolsmith, called a couple of days later to confirm the breech block issue. The repaired barrel / slide unit was FedEx'd back (prepaid by Glock) and received on 16 Oct 2015.

Although the gun was well out of warranty and had been dry-fired over 19,000 times, there was no charge for the repair. That pleased me very much. The next time my eyes start to stray towards the Sig 320, I'll remember when I expected an expensive evening with Glock and she said, "Let's just eat in. I'll cook something."

Many thanks to SecondsCount, Nephrology, and LokNLoad.
