Glock 30 SF FTF *pics opinions on why?

[schufflerbot]

Only fired 50 rounds through this thing, all were flawless except this one. Ammo was factory Federal range ammo, after re-racking the slide the round loaded fine and fired without issue.

Anyone have any ideas as to why this may have happened? I bought the gun used but it looks and acts brand new inside and out. I had not cleaned it prior to taking it to the range

My guess is that is probably the issue right there. I have a Glock 30 SF, and when I cleaned mine straight from the box it had some fairly thick grease in a few spots.

Some of that 'grease' is supposed to be there. The copper colored stuff is an anti-seize grease that slicks things up and helps with break in.

Excellent opportunity for a clearance drill...

My Glock manual says, pg 26 "Your GLOCK pistol should be cleaned and lubricated as follows: 1. when brand new, before the first time it is fired..." The manual also mentions on pg 12 in the grey box "Before firing your GLOCK pistol, run a clean patch through the barrel..." My Smith & Wesson M&P 15 manual says the same thing, pg 35 under Cleaning and Maintenance, "Before using your firearm for the first time, it should be cleaned." So while that grease is supposed to be there, otherwise the factory wouldn't have put it there. It does seem unlikely that it helps with break in if you are supposed to clean it out before firing.

He said he had only fired 50 rounds through it, but did buy it used. No telling how many rounds have gone through.

I'd fire another 100 rounds through it and see if it does it again. May have been an issue with the round itself.
Having owned many glocks over the years and having shot many more than I've owned, it's been my experience that very dirty glocks operate flawlessly and brand new glocks operate flawlessly without being cleaned prior to shooting.

That's also been pretty much my experience. The only time mine has done anything like this was when shooting weak hand. I figure that was operator error and didn't have a strong grip.

The manual also clearly states "...Note that the copper colored lubricant found on portions of brand new GLOCK pistols should not be removed, as it will help the long-term lubrication of the slide.". I was not advocating not lubing the pistol - rather that the copper colored 'grease' was there for a reason. I actually did miss that this was a used pistol so the issue was probably moot anyway.

[Jago668]

Don't worry so did I. So much for both our reading comprehension. You are correct about the copper grease, I completely missed that in the manual.

The g17, with new mags will never jam. It survived military trials. Any other glocks will need a bit of lube, especially when new. My g26 jammed once when it was new when I shot without clean & lube. It has since been flawless.
