First time disassembly. Maybe 150-200 rounds through it, max.

So, i got the slide release pin out without a problem, but this slide will not push toward the front and off, no way, no how. It goes about 3/4" front from the rear. Clears the rearmost slide rail, but will not go any further front. I tried to "muscle it" but no dice. Wiggle back and forth - not much wiggle.

I'm not sure why it's stuck and don't want to get too aggressive with it and break something it might be hung up on. When it's as far front as possible, the trigger will pull without moving the hammer, but the hammer looks very tight against the slide, like maybe that's what it's getting hung up on. Is this even possible? I tried to pull the slide back, goes back fine and I can pull the trigger about half way (it will move the hammer then) to get the slide to clear it, but still doesn't come off.

Thoughts?
