I ended up tearing the gun down. I have less than 1 tin of pellets fired. Cleaned everything up, lubed it... My pins were all seated, but also easily came out, but with the gun apart the firing pin still seizes and I can see its not the pin... There was some slop in the pivot on the cocking lever that I thought may have been the issue, as without the hammer spring in, the firing pin would bind, and if I applied pressure it would release and slide.
I could reassemble, cock 5 maybe 10 times fine, then it would lock up.. I can't 100% see the issue. My guess is its torquing it self and wearing the metal, creating a burr and jamming it. I could feel burrs on the hammer spring bushing and inside where it seats it looks worn. But it binds without the hammer bushing in, so it may also be where the cocking pin slides is worn and now torquing it self up and binding.. hard to explain but if you took it apart you would understand. I just don't see obvious wear on the firing pin, and its hard to see into the channel the firing pin slides..
Waiting on some moly paste, but it may be too late, the lube they recommend is not enough to prevent premature wear. Will call umerex monday.
