I have a 1927(maybe 1926)(serial just over 12000) Model 54 in .30 Gov't 06 and the trigger pull is really not all that bad for that type of trigger. I like the gun in it's original state. Besides, at this point in time, there's not much reason to mess with the trigger no an old 54.
I have hunted with it a few times and, in a hunting situation, the trigger pull is not an issue.
The George Madis book says there were 50161 Model 54s built.
The Roger Rule book says 50024 "standard" and 2005 "special Model 54s built for a total of 52029.
I believe the books much more that the worthless "Blue Book"!
