There was more hand fitting back then. Parlty because machining was not as precise. Which also makes then a bit harder to fix when they wear down. Not to mention there are not many smiths that can ever do that anymore. The newer ones are designed to minimize that sort of things while maintaining the same smooth trigger. They did a wonderful job of accomplishing that. The new ones have great triggers. A lot of older ones are safe queens for fear of wearing them out and not being able to fix them. Depends on what your wanting to do with them.Yeah you can buy a new one for under a grand but the older models are fetching better then new prices all over the internet. Like many firearms folks put a premium on the older models based on truths, rumors, myths or legends. My previous research says the older models had a lot of hand fitting and polishing and the triggers are supposed to be top notch etc. Any truth to it??? Maybe but that's their selling points for the old production.
