Contenders with the trigger pivot forward in the forend were the first 195,000 and were more difficult to open. They were originally called Type 1 frames. TC came out with the easy-open frame with the pivot pin directly above the trigger, that's the Type 2. After that, G2.
So, aside from the G2, you can sort frames by the location of the pivot pin for the trigger assembly.
They are 100% right, the whole set-up wouldn't be over $450.
