......OK, it was me.....

......since I had let it slide the last two times I had been to the rifle range. So basically, I cleaned 9 guns today, and by the time I got to the last one, I was TIRED. The last gun was my wife's Glock 19. I got it apart and cleaned just fine, but when I reassembled it, I accidentally installed the guide rod/recoil spring assembly backwards. So of course, when I mounted the slide assembly back onto the frame and pulled the slide back to lock it, I so thoroughly jammed up the works that I can neither move the slide forward to remove it, or pull it back to lock it back.
I tried to find out if anyone else on the Interwebs has been as dumb as "my friend", and what they did to fix it. The only recommendation I found, besides taking it to a Glock armorer, is to cut the protruding plastic guide rod off, get the gun apart, and install a replacement guide rod/recoil spring assembly. I gave Marty, Crossfire's husband, a call this afternoon. He's a Glock armorer, and I thought he might be able to help. He told me to bring it by his office tomorrow and he'd check it out.
In the meantime, have any of you ever heard of this kind of problem, and do you have a solution?
