5 drops? Or one drop in 5 locations?

One big drop that covers all five would be my application.

Lube it. Pull that slide back and let it snap back on it's own and I bet it will run like a dream.

Video looks like user error to me.

Both times you released the slide your entire hand and fingers stayed on the slide.

One on each side of slide and let gravity do the work, and one very small drop spread around on thinly on barrel.......where do the others go ?

I've had/have a lot pistols and none of them stall on a controlled slide release. Those include CZs, Sigs, Walthers, and the Glock before the mishap. So, if that was my first experience, I wouldn't have any issues with accepting it as-is. But, I know it didn't operate that way prior to my son's goof up. Something happened and just trying to figure out what.

It looks to me like you're not letting the spring do it's job so it's "stalling" and resting somewhere on the barrel lug/locking block engagement, where a bunch of mechanical things happen and need that spring power to get it in there.

I don't know if all your other guns were small with short recoil springs, I'm sure I could get my 43 do the same thing if I ride the slide home with my hand.

Pretty sure all of my Glocks would do this.

1. Connector-Trigger bar interface
2 One drop left slide rail groove
3.One drop rightt slide rail groove
4. One drop underside of slide above barrel-rub it in
5. Barrel locking lugs.

I also put a very light coating on my barrel and barrel hood, although Glock doesn't mandate it.

Might be to late, but that initial coat of hard greeze, don't clean it. Work and fire gun with it in place. Glock's recommendation.

I have a different opinion on Glocks and lube. Glocks don't like being wet at all.. one very small drop on the 5 lube points is all....

I dunno, generally my....oh you said glock. Yeah thats lubed too.

I couldn't get my Gen4 17 to do this, even slowing way down where the barrel jumps into battery the spring still gets it over the hump.

Troubleshooting Flowchart :

Does gun go Bang every time while actually shooting ? If so , no problems .

Does gun not go bang everytime while actually shooting ( brand name fmj ammol? If so avail yourself of nearest Glock Warranty Station.

In the position its sticking it would seem to be the trigger bar where it meets the firing pin plunger. Maybe its canted off to the side and when you release the trigger a little it moves into place. Thats what I would look at. Operate the trigger with the slide off and check that. You can also look at the firing pin plunger and make sure that is not gouged and operates smoothly.

swinokur · Jun 20, 2017

is this part scratched, bent or gouged? as mentioned, also check the firing pin safety plunger

this would possibly indicate a bad interface and the source of the friction

Any updates from the OP? How does it shoot?

Range day is this weekend.

Gonna check the trigger bar when I get home.

Yoshi · Jun 22, 2017

Does the trigger bar hump/bump travel directly over the firing pin safety or to the right side?

swinokur · Jun 22, 2017

The little bump on the side or the main raised part?

The trigger bar sort of looks like a shark fin. When the slide moves forward the pin rides over the fin shape depressing it into the slide body.

You notice how the pin has chamfered edges. People modify this pin by removing it and polishing off the sharp chamfer edges. Supposedly it improves trigger feel. I did this but I didn't notice and difference.

I tried every one of my Glocks and none of them did this. I walked the slide all the way and they all went into battery. There is a slight tight spot just about where the OP pistol fails, but I can't figure out what's causing it. A picture or two of the frame without the slide in place cold be worth a thousand words.

OP, post a few pictures. I have the same pistol, I can compare mine with the pictures you post.
