Your problem sounds to me as extremely strange, i have disassembled Glocks more than xxx times but never experienced what you describe, although you will get problems disassembling when you pull the slide back fully and not pulling the trigger (safe direction) before you try to disassemble, in that state there's no other cure than racking the slide and pulling the trigger at the same time.

BTW .40 is a nice caliber but be aware of the feedramp/barrelmouth issue with Glocks, be careful especially with reloads "kB" i think they call it..

So I read your comment on the feedramp/ barrelmouth matter. What's the issue with that on Glocks? I've read a couple other posts that may be related to that, but haven't read too far into the forum postings yet. Reloads do scare me a bit when fired through an auto loading handgun. I hate to ask but what does "kB" stand for. (Killer Bullet?) I'd like to know more about this feedramp/barrel mouth issue. Please Comment.

Thanks in Advance,

i may have a simple solution to your complicated problem

let me start off by saying that iv done the same thing, we start striping the glock like so


remove mag
check the chamber
dry fire
then start the process of taking the slide off

ur problem may have been in the first 3 steps, it sounds like you got alittle carried away and forgot to dryfire after racking the slide to check for a round in the chamber


just a thought

KB is an abrieviation for a Kaboom.

As for your derailment, a similar thing happened to my 21sf while putting the slide back on after a cleaning. I had the slide half way on, and inadvertantly pushed/rolled the left side of the slide up off of the center rail while it was still moving backwards (still on front rails). I gently slid it back into place and checked it... no damage. I have since put 1000+ rounds downrange with it. If it bothers you, have your gunsmith look it over for you. BTW I can't do this with my 19 as the rails are too close together.

Couldn't help myself.

You are terrible Todd.

Hrm weird, I thought I had a post in here but now it appears it never made it.

I was thinking perhaps the magazine was still inserted into the grip and pushing up on the slide as it was being removed, and perhaps this caused the slide to "derail." I can't think of much else which could cause this. Just to be thorough, during the process of checking and clearing the chamber before disassembly, also remove the magazine, THEN remove the slide.

If you're already doing this, well then I'm out of ideas.

Looking back at this I think I must have forgotten to dry fire the gun before removing the slide. So I have to say I'm leaning toward what Knox mentioned. Over the weekend I fieldstripped it multiple times (too many to count) and each and everytime it broke down as it should. I even forgot to remove the empty magazine quite a few times and it still didn't derail and stripped with no problems. I do however try to remember to remove the magazine first.

I've had people bring Glocks in in a panic in this exact state a few times before. I've done it on purpose to show people how to fix it. I've had some non-Glocks come in this way, too. Pretty much, it happens. Just be careful putting the slide back on. Don't throw it back together right away. And if it happens again, just give it a good whack on the back end.

You're not alone,I've done this with my 36.It happens.!
