So recently I picked up the G29SF and while I'm trying to field strip it, I'm noticing the slide doesn't come off as easy as on my other Glocks. It get to the point where the recoil spring sits into barrel and stops...I then have to push up on the spring in order to get the rest of the slide out. Looking at it more closely, I'm noticing the recoil spring is getting knocked away from the curved ledge that its s'posed to sit in...its happening when I put the slide back in. Its moving just enough to where its hitting on the curved lip in on the inside of the frame. Anyone ever see this? Cause(s)? I tried to look and listen as I put the slide back in slowly, could it be the slide lock? I also have an email into Glock, hopefully they reply.

 

What it looks like before reinstalling the slide:

 

 

What it looks like after its removed...moved from its original spot:

 

 

Tad blurry but you can see the spot where the back plate of the recoil spring is hitting/catching the frame:

 

Ok, I think I'm onto something...taking a closer look, all 3 Glocks recoil springs move out of their curved ledge. What I'm seeing is the G26 has a lip in the frame that the end of the recoil spring is catching on...the G26 has no lip in the frame...and the G19 does have a lip in the frame BUT the end of the recoil spring is much smaller and does not hit the lip. Does that all make sense? lol

 

All 3 recoil springs not in their respective curved ledge, left to right G19, G26, G29SF...note the end of the G19 recoil spring is much smaller:

 

 

G26 left no lip, G29SF right with lip...G19 not shown has same lip as 29SF:

 

I've seen that happen with the duplex recoil springs. Listen to whatever GLOCK says but I have not seen any consequence of this.

Ok so heres a silly question...why are the springs moving out of their curved ledge to begin with? Are they hitting the slide lock on the way back when reinstalling the slide?

OK, before answering this post I just grabed my G26 and pulled the slide off. The sheet metal end of the recoil spring was out of the 1/2 moon cut as you describe. I pull the slide twice and both times it was the same.

 

I believe the sheet metal plunger is guided in the frame and as you pull the slide forward it's sheet metal and slides down when its not held captive by the frame.

 

Never thought about it much. I can just tell you my pistol performs flawlessly.

Right, and the reason you prob never noticed this is because the 26 doesn't have that lip in the frame like the 29 has. I just find it odd that the slide on my 29 won't slide off in one fluid motion...I have to fiddle with the spring to clear the lip. I agree it doesn't have an effect of the performance.

Don't fiddle. Just wrap your left hand(if you're right handed) around the barrel slide assembly and push the spring back up w/ your finger tips. Talk to GLOCK and report back please.

Thanks, defitely will.

Some more info I was able to gather:

 

Regarding the guide rod position, the half-moon slot is used only to position the guide rod properly for reassembly of the slide on the receiver. The rear end of the guide rod drops down out of the half-moon slot into a channel on the receiver during normal operation and doesn't touch the barrel at all.

 

When the slide is removed, the barrel lug again catches the rear end of the guide rod and pulls it out of the receiver channel, but typically the guide rod does not fully seat in the half-moon slot as it comes out. There is nothing to be concerned about. What you have observed upon removing the slide is completely normal.

 

The excellent photographs below, taken by GT member Phantom465, show the guide rod in the proper position for reassembling the slide on the receiver and the normal position of the guide rod after the slide is removed:

Because when the slide gets put on the frame the spring rests againts the frame. In other words, the spring never touches the barrel.. That ledge is there only to hold the spring while you remove the slide. Push it down to the bottom of the ledge and re-install slide.

 

It is normal, your Glocks are fine.

This is where your springs rest when the slide is installed. It never touches the barrel. Try to put spring and barrel on frame without slide, you will see how it all lines up.

Right...I'm understanding now that this is all normal operation...but the recoil spring on my 29SF is still hanging up on the lip in the frame when I try to take it off...thats what preempted this thread from the start. Is this also normal operation?

I don't have a G29 but I would think this is normal looking at the lip your talking about. Try lifting the front of the slide as you pulling of, so to be at an angle when the spring gets to that point. And maybe some oil on the lip will help.

 

Does the spring have a rough or damaged edge?

Right, thats what I've been doing to remove it, lifting up on the slide and simoultaneously pushing up on the spring to clear that lip. Spring edge looks fine, not bent or anything. Someone on GT mentioned this:

Perhaps the rear flange of the guide rod is a little bent and lets it drop more than typical when removing the slide.

I meant if the flange was rough or damaged it might be getting hooked on the lip. If not, I think it would just be the nature of the design to have to lift up as you pull the slide off. My best guess is that it is normal for that model.

i gotta check this on my g20, never notice this ever happening to mine. you sure your babying it when taking apart?

Your G20 has a different frame and RSA. It will not experience this.

Ok, so I s/w Glock support. They want me to throw some rounds down the pipe and see how it is. If it still hangs up, they said to call them back, that they might want me to send it back for them to take a look at it. Keep everyone posted.
