Tried that - numerous times....Grab the recoil spring and pull it...

Issue resolved!
I managed to pull the guide rod forward about an inch and a quarter and it locked in that odd forward position, relieving pressure on the barrel which I could now wiggle about.
I then pulled the trigger a couple of times while working the slide back and forth lightly while actuating the slide releases and it released. The slide moved forward and off the frame.. Oddly the RSA was perfectly seated as I recall when I installed it.
I inspected everything closely. No galling of metal or plastic parts. All appears normal.
So I carefully reinstalled the barrel and rsa and with the pistol inverted, gently moved the slide back onto the frame.
It went on normally and with ease. Functions perfectly. Trigger feels the same as before.
Once again - thanks all!
Whew! Glock Perfection after all! Glad it worked out OP!
I agree with your assessment. The little metal rail sections on Glocks can be misaligned if you do it Jackie Chan fast and hard. I’ve done it many times but not to your level! Lol!Indeed - big sigh of relief for certain. I was puzzled since the second it happened.
It felt as thought the slide was locking/hanging up on the back of the slide in the trigger mechanism..
I would wager to guess that somehow I ever so slightly misaligned the slide when reassembling and it did not line up as it should have at the back of the slide in the trigger group. Just a guess from where it felt it was hanging up.
Many thanks again to this wonderful forum!
