Mossberg 590A1 Trigger Question
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 net i only find graphics with low resolution.

I have a 590a1, never had a reason to take the trigger apart. Did you have a problem?

no, no probs at all, but the weight of pull of the trigger is a little bit to high for competition use and if i get the main spring(s) lighter or leave one (the smaller one) out i'll reduce the weight and probably still have enough striker force of the hammer, just what i thought 'bout

I don't shoot comp so as far as the pull on my 590 goes it suits me like it is. Thinking about it, seems like it has very little creep and is crisp when squeezed.

You must be at the top of your game if concened with trigger weight on a pump shotgun. If I had a complaint about mine it would be the drag in the slide but that is smoothing out everytime I shoot it.

i mostly shoot slugs and there a light trigger in combination with a ghostring sight/rifle sight is a real advantage
