TT-33 not auto cocking

[Dyspnea]

I bought a pair of tt33's from tradeex, I took them out too the range things were fine to start but after 80-100ish rounds my one pistols stopped auto cocking.

I pull back the hammer and it locks into postion. Pull the trigger and it goes bang, loads a new round, but the hammer locks in at the half #### position or down. I manual rack the slide and the hammer go back to half #### or down.

I switched the hammer and sear groups around and the other pistol will do the same.

I disassembled them both completely and swapped parts around, but the problem remains.

Do I need a new hammer or can I remove some material from hammer to make to the sear spring seat better.

You should quit dicking around with it and possibly making things worse. Get on the phone and call Anthony at Trade-Ex and tell him your problem.

Trade-Ex has an excellent reputation as far as service goes. If you fired less than 100 rounds with the pistol, then something has occurred that makes it malfunction. It would seem from your description that it is a Factory problem and it is possible that the sear or hammer has suffered some damage. Possibly a defect in the steel or broken sear notch in the hammer.

If you start diddling around with the internal parts and trying to modify things yourself, then you will void any possible warranty that you might have on the firearm.

Since the firearm functions when you manually cycle the action, the slide possibly is not coming back far enough to fully #### the hammer, or, it is also possible the disconnector is jamming a bit, so that when the slide comes back, the disconnector does not allow full engagement with the hammer so the sear is not in a position to keep the hammer back, but the hammer then follows the slide forward and is stopped by the half #### notch in the hammer.

As the firearm functioned as designed for 80-100 rounds before this happened, it is possible that some dirt or crap got into it, or some part got bent or out of line, either through firing or from disassembly, etc.

PHONE TRADE-EX.

+1...take it apart to clean and inspect, but don't modify anything or you're up the creek.

Doesn't hurt to give them a call.
If you happen to discover the problem let us know !! I have not completely disassembled the hammer/sear group on one so I'm not sure what's involved.

Did you soak all the GREASE out of the Trigger/Sear Groups before you went to the range?

Grease is a wonderful attractant for dust, fouling, leftover crap from the powder burn, dirt, sand and anything else that sticks and gums up the works.

If you have the PARTS, the Trigger/Sear Groups may be disassembled for servicing, but it is NOT a good idea unless you know precisely what you are doing.

FIRST thing I would look for is dirt and crap in the action, slowing the critter down.
