View Full Version : Mossberg 590A1 Trigger Question

01-04-2012, 09:47
i own a mossy 500 and a 590A1, after disassembling both trigger groups i discovered that the 500 has a single trigger main spring (part 35) and the 590A1 has a double trigger main spring. it has the same trigger spring like the 500 plus a smaller (smaller in diameter) one inside the bigger (normal) one.

is this quite normal? why has the 590A1 2 trigger main springs? to enhance the striking force of the hammer?

if i have a closer look at the manual there is only one main trigger spring.
has anyone a good detailed exploded drawing of the mossy 500 and the 590A1?

in the www. i only find graphics with low resolution.

thanks fellows
