i just aquired this gun recently not knowing anything about it and
getting ready to clean it i noticed that the trigger has no resistance
like there is a spring missing.
i asked the guy i traded it for and he said he never noticed it not knowing a bunch should i tear it down via youtube reference or just leave it?
In most marlin's you will cock it back and if there isn't a snap as you pull the trigger back then I suggest you take it to a smith and have it looked over.
Marlin's have a solid break in the trigger when it allows the hammer to fall.
If its not cocked then you have some play.
