new Glock 21sf - guide rod oddness?

Just bought a 3rd gen glock 21sf in (apparently) mint, unused condition.

I notice that when I do a field strip... removing the slide... that the guide rod is sitting on the wrong "ridge" there at the back of the barrel.. it is sitting too high.

I put it back in its correct position and put the gun back together. It all seems to operate fine with dry fire and all.

Then, I field strip... and that rod is sitting up too high again. Is this normal? My guess is that there is something in the act of doing a field strip that shoves that rod up a notch.

This doesn't happen with my Glock 19... but I notice that the guide rod is, indeed, pushed up slightly from it's proper position.

Can any of you try this on your 21's and check it out?

I wonder if it's in need of replacement. Maybe worn down and not strong enough to stay put?

The thing looks incredibly mint... Being an unknown history, I can't be 100%.

If anything, the gun feels a bit tight.

I was going to ask on a glock specific forum, but for some reason, it told me I was banned!....so I couldn't register.

What the heck. The firing line is excellent!

Check it out.

I was googling for some information about lubricants for glocks and found a Glock FAQ.

Just a few lines down from the lubricant questions (apparently any gun lube will do fine), I found this at GlockFAQ.com regarding the unseating of that rod:

"How do I keep the recoil spring assembly seated?
Don't worry, it's not supposed to stay seated. When you re-assemble your Glock the end of the recoil assembly will fit snugly into the semicircle cutout in the barrel. During firing it will move down slightly, into it's correct position. When you disassemble the gun you will see that it has moved out of the semicircle a little bit. This is completely normal."

That is correct.

The notch is there to make reassembly easy.

When you first assemble the gun, (assuming you don't pull the slide too far back during reassembly) the spring guide will still be fairly close to its reassembly position. It doesn't quite touch the barrel, but it's close. It actually bears against the frame and is just barely out of contact with the barrel.

The first time you rack the slide, the barrel tilts down at the rear during the process and that bumps the rear of recoil spring guide downward just a tiny bit. The spring guide will stay more or less in that position from that point on and that's what you're seeing when you disassemble the gun.

Yep my 21sf does the same thing. Never has been a problem.

Your are fine... go shoot the snot out of it. Build some confidence.

If you would, post a couple pics of the rod seating before firing (after cleaning) and after firing (before cleaning) to be sure. I'm curious, I've never noticed this with my G21.

Actually, I apologize and take that back. When I remove the slide the guide rod DOES pop out of its semi-circle seat, and I do have to pop it back in before assembling. Never thought about it but it does feel a bit odd now that you mention it.
