Always Function Check After Cleaning. But why?

[twentyeggs]

This thread is mostly for people familiar with Glocks. I understand function checking is to make sure it is assembled correctly and.... functions. I've taken my glock apart many many time without incident. However, the other day after cleaning. I did a function check and it felt weird. It wasn't racking smoothly, it felt like it was catching or hitting something about 1/8" before going into battery. after manually cycling about 3/10 rounds would get stuck and the slide would hang up that 1/8th inch. you could see the lip on the back of the casing, sticking out of the barrel over the feed ramp.

When i re racked it, there was a failure to eject and i would get a double feed. So I basically took it back apart, just a basic field strip and back together and it is smooth as normal and functions like normal.

I am just wondering what exactly caused this. just curious as to what the problem could have been. When you put things back together there really is no room for assembling it wrong so I am a little confused as to what could have cased something like this.

If you have any ideas, fire away! Thanks.

Maybe you're just having a bad day.
No only did you screw up your reassembly of the simple Glock, you posted this in the 'Centerfire Rifles' forum.

Q - Do you function check with live ammo in your home?

...after manually cycling about 3/10 rounds would get stuck ...

Tell me you weren't manually cycling rounds at home through a gun you suspected to be malfunctioning?

Maybe the guide rod and spring not in the groove correctly? I've had that happen before and it went back together but wouldn't cycle smoothly or it hung up.

Someone you install the magazine release incorrectly. Or a problem with guide rod. But yes don't play with live ammo at home.

Should have function checked this thread.

Sounds like a guide spring issue to me. I always rack the slide and pull the trigger to function check after reassembly. It makes sense to do that. After that, rack a live round in the chamber and reload the magazine for storage or carry. Nice and tight.

Don't just pull the trigger, point the gun straight up, drop a wooden pencil down the barrel, eraser end first, and then pull the trigger. The pencil should jump substantially or even come completely out of the barrel.
Doing this insures the striker is actually functioning.

magazine?
sounds like guide rod, do you have a steel one or oem?

its an oem one. After reassembly I did a function check, that when I felt the rough slide action. I always use the pencil thing to check the striker and it worked. It was only after reloading and racking in the first round that I realized the round would hang up.

I am thinking the guide rod was the issue too, since a simple reassembly is all it took to fix the problem. Is there any way the barrel could be seated incorrectly? The block on top of the barrel seemed a bit loose when dry cycling.

The whole incident lasted 2 min from start to finish, not a big deal. Just wondering if it has happened to anyone else and looking to learn something if there is something to learn, or if it was just a case of putting it back together too quickly and being sloppy.
