The trigger on my 23B is is not great but OK, not so heavy I can't live with it. The 23A had a somewhat rough trigger with some creep. I had a gunsmith friend look at it and it came back with just a hint of creep (which I don't mind) and a pull slightly under 2#. That is probably too light for most folks but since I spend lots of rifle time using set triggers it almost feels heavy. If i remember right he did some light stoning and maybe clipped a spring - he tends to be very conservative when it comes to triggers. It still has plenty of engagement so is safe.
On a Marlin Model 80E (1930s) with a similar trigger arrangement I had a very slim set screw put the trigger (bearing on the receiver bottom) so as to adjust much of the pre-travel out of it. The adjustment and a bit of polishing yielded a crisp 3.5-4# pull. That, by the way, is a nice rifle also.
