I just installed a 9mm Lone Wolf barrel in my Glock 23. The slide seems to be locked slightly back past the unlock position. I can't get the slide to cycle without squeezing the trigger and pushing the new barrel down a little. I can then lock the slide back, but upon releasing the slide it goes back to the same position. It will not completely reset therefore I cannot remove the new barrel.

I have noticed the barrel is really loose and when the slide is locked back. It seems like the recoil spring assembly is caught on something other hand the barrel locking cams.

Anybody have any ideas how to fix this?

Thanks in advance!

That's an odd one.  Post pics, maybe?  I would like to help.

You're sure it's a CONVERSION barrel, correct?  

If I understand you correctly, the slide's not going back fully into battery, correct?  It's "sticking" before that point?  If this is the case, I'd say (and of course, your pistol is unloaded at this point, right?)  let the slide go to where it stops, then give the back of the slide a good smack, to push it into battery, so you can pull the trigger and strip the pistol, to get the barrel out.

From there, look for "witness marks" where things might've been to tight.

Those barrels are made to tight tolerances.  Usually this is just a tight chamber issue.  But I do know that with mine, there were "witness marks" around the hood area, indicating a pretty tight fit in the slide and breech area.  I filed and stoned these down a bit.

It's possible the barrel is slightly out of spec, although LWD has a great reputation for making great barrels.

Yes, I am sure it is a conversion barrel. I recently purchased it from a reliable member of the board here. It is a blind marked 9mm Lone Wolf barrel. I will try to take some pics, but I am not sure how to post them.

Do you think I will damage the gun by hitting it back into battery (slide closed and ready to fire position)?

What about gripping the recoil spring pin to try and release it into proper position?

I hope this helps. I know they are not very good.

I don't think it'll damage it by shovin' it into battery, but I must admit, I'm still not 100% clear on exactly what your gun is doing now.

It seems that it's not going all the way into battery, therefore you can't pull the trigger to release the Firing Pin, thereby allowing you to pull down the Slide Lock and disassemble as normal, correct?

There is a way around that.  Lock the slide back, then look at the "underside" of the back of the slide.  Remove the Back Plate from the back of the slide (you know how to do this, right?  press down on the visivle portion of the Firing Pin Spacer Sleeve, then ease the Back Plate off), then remove the Firing Pin Assembly.  This allows one to then return the slide forward, and strip as normal.  

I can't guarantee this will work, though, as I'm still not quite sure what's keeping the slide from fully returning to battery.

Will the firing pin assembly just slide out the back of the slide?

You are correct it will not go completely forward into battery. It seems like the recoil spring assembly is stuck on something as the barrel is really lose when the slide is locked back. I know this is not supposed to be that way. I can wiggle it around about the .12 of an inch it says you should pull the slide back to release it.

What about the recoil spring "pin"? Could I grip it with some pliers and pull it forward to reset it into the barrel?

Okay.  Yes, once you take the Back Plate off the slide, the Firing Pin Assembly will come right out.

The barrel IS supposed to move around like that when the slide's locked back.  All Glocks, and most semi-autos for that matter, exhibit this.  Perfectly normal.

I'm not sure what you mean by "recoil spring pin", maybe you're referring to the end of the Recoil Spring Guide Rod?  I don't think tugging on the end of it will free things up, but might give it a try.  If you do, don't pull on the end of the rod itself, grab the rod and pull.  That end cap can come off, it's not supposed to.

Of course if you damage this rod, a new Recoil Spring Assembly is very cheap, usually 5 or 6 bucks.

I suppose it's possible the "back end" of the Recoil Spring Assembly wasn't put in it's correct notch in the bottom of the barrel when you initially assembled the pistol, and this may have created the problem.  But, there's not a whole lot of room in there for the rod to get "out of place" to bind things up..............maybe part of the back end of the rod has broken, and is lodged somewhere around the forward locking lug of the barrel.  Hard to say, haven't seen this problem before.

I'd say yank that Firing Pin Assembly out of the slide, run it forward, move the Slide Lock down, as per usual disassembly, and see if the slide comes off.

I wish I could be more helpful, friend.

Let us know how it goes, most more questions or pics.  I'm sure we can figure out something.

Well this had a happy ending. I was able to remove the slide with the advice ViniVidivici game me. Once I removed the slide I was able to remove the recoil spring assembly and the Lone Wolf barrel.

Upon closer examination of the barrel, I discovered what a dumba$$ I am. I thought I had purchased a 9mm barrel for my Glock 23, but in fact I had purchased a 9mm for a Glock 19. Aparently the barrels are not the same length along with the recoil spring cams.

So to end this fine tale...I now looks like I have a Lone Wolf 9mm barrel for sale. Any takers?

Well, glad to hear you were able to get it apart.  Now at least you can throw the stock .40 barrel back in and have a functioning pistol.

Might as well put it up on the EE, surely someone with a Glock 19 who reloads and wants to shoot lead with it will take it.  Good luck sellin' it.

Yeah, gotta be a conversion barrel.  You already know though.
