On Friday my TT33 became a jam-o-matic and I took it home after 10 shots. Knowing little about it, I decided I'd follow this sticky and it became obvious that the disconnector was binding. I thought I'd touched up the top of the disconnector, but apparently not enough. I also put white grease in that area, and more grease on the slide rails than I usually do.
It no longer binds, 'tho I'll have to test it to be sure, but it feels great now when I rack it, and the trigger is smoother, though no lighter, oddly. It was 5 to 6 lbs before, and remains the same. Would removing a coil from the spring help, or make things worse?
In any event, I now have a much better understanding of this pistol. I tackled it with confidence given the great pics and instructions.
No way on earth I could get the hammer pin back in by myself, though. I managed to hold it in the right position and had my partner insert the pin, otherwise I'd still be trying.
Much appreciated sticky, Mr. Bickle.
