If the slide will go back all the way without the spring in, I would think that the spring just isn't being seated properly. Found this thread this morning and disassembled and reassembled my PT140Pro a few times, trying to figure out what might be preventing slide movement.
When disassembling mine, after the pin's been removed, I have to pull the trigger to get my slide to release completely. Wondering if you have to also. If not, it may just be a matter of pulling the trigger while sliding the slide back to its rear position. When putting the slide back on, guide it down the frame to the point where it's stopping, keep slight rearward pressure on it as you pull the trigger as far as it will allow.
Also, saw that someone asked if yours is a Pro model. I had a PT140 before the Pro was out, and had a couple similar-sounding reassemby probs with it. I was always able to reassemble but a few times I recall it fussing like your is. The Pro came out, I picked one up, and have been happier with it than its non-Pro predecessor. Just a note - if you like your PT111 and it's not a Pro model, might think of upgrading to the Pro.
Anyhow, I hope the trigger pull works - let (us) know, I'll keep racking my brain as to what the prob might be.I'd surely think it couldn't be thespring length if it's the same spring you took out of it. If you'd take it to a shop I'm sure they'd slap it together in 10 seconds, making us all feel like idiots, but knowing is knowing. Keep (us/me) posted - got me curious.
Gonna go disassemble mine again and play with the spring. You wouldn't have gotten any debris in the spring which would prevent it from fully extending or rectract I assume...
