Question Problems Removing Slide on VFC/Cybergun M&P9, Persistent Trigger Assembly Issues

First, the main problem: pulling the slide all the way back and clicking the take-down lever into the vertical downward position, the slide comes forward, past the usual "rest" position, but does not slide past the trigger assembly for a proper take-down. I cannot remove the slide as a result. The pistol is otherwise functional. I have tried holding the trigger while gently easing it forward and I have also pulled the slide firmly near the front of the mag. I don't want to really yank on the slide for reasons I'll explain below.

Background: I have two Cybergun/VFC M&P9 (full size, not compact). They are obviously not competition grade (I use them purely as a backup to my AEG for milsims and indoor skirmishes) and are currently mostly stock parts except for a replacement slide on one of them and I have previously replaced a trigger assembly with OEM parts on the other about a year ago - a metal component inside the trigger assembly sheared off.

Recently one pistol stopped working. Not only was it not firing, I could not remove the slide because it would not slide past the trigger assembly. After considerable effort, I managed to remove the slide, but it was clear that the hammer was not popping back up into the cocked position after racking the slide. Having replaced the trigger assembly on one pistol last year, I figured it was a similar issue and ordered two new replacement assemblies (I like having a spare on hand).

I have two other pistols, a TM PX4 and a KJW P226E, and I can remove both slides with zero difficulty using the take down lever (P226) or button depress (PX4). Before both these M&P9 pistols began experiencing difficulties with the trigger assemblies, I could remove the slides, usually with a small degree of resistance and occasionally manipulating the trigger, but never having to apply too much force.

While using one (working) pistol as reference for the other, I ran into resistance removing the slide on the working pistol, and used a little more force than usual, and got the slide off. Once I had the slide off, however, the hammer was stuck down, much like the broken pistol - it appears that I had somehow jammed the hammer in the process of applying force to remove the slide. (? - I'm not sure)

So... I broke one pistol trying to fix the other: two broken pistols. I sighed and replaced both assemblies, figuring that once I replaced the assemblies, the slide removal problem would disappear. I lubricated all necessary parts, and reassembled the pistols. After replacing them, the pistols both worked fine - fired consistently, giving expected FPS. However, even after replacing the trigger assembly, the pistols feel like they are resisting having the slide removed - following the steps above, I still cannot remove the slide easily on either.

Now I have two working pistols, but whatever I have done or however I have reassembled the parts, the slide doesn't want to come off on either frame. My worry is that if I try too hard to remove the slide, I'll end up breaking a trigger assembly again, and I'm out of spares.

Any fellow Cybergun/VFC M&P9 owners run into a similar issue? Any pointers for dealing with this issue, or maybe a little trick to removing the slide which I'm not aware of?

I've watched a number of disassembly videos on YouTube, among them:

None of them appear to experience the degree of resistance I encounter when trying to remove the slide.

Thanks in advance for advice!
