How important is it that I replace the plastic trigger parts and safety on my 590 with the metal parts from the 590a1?

Anybody have experience with these failing?

Replacing the safety button is a good idea, but the trigger guard will be fine, not much talk abouty them failing.

I've heard of one failing once maybe. It's not an issue. The plastic safety button can be an issue in extreem cold, and metal ones are cheap enough that's it's not a big deal to swap out. (don't loose the detent ball)

I would stick with the plastic trigger group on the Mossy because the metal one is cast aluminum (LIKE THE 870 Police). The plastic safety is probably GTG as well because it is thick plastic supported with a metal liner underneath, and I do not see how it could break as easily as many people say. However, I changed mine out with the Brownells enhanced safety and it is so much easier to actuate because of the raised notch. It is made of steel.

The trigger guard isn't a huge deal, and maybe not even a big deal. Desert01 has a lot of experienece with the 500 in .mil service and is still very involved with Big Army on the platform. He's said that they never had a problem with the plastic units. The metal one would give you some insurance/peace of mind though.
The metal safety would be an upgrade that I would do on any 500/590. The plastic ones do have problems, and have broken with heavy use. If you don't use your shotgun a lot or run the risk of banging it around, then don't worry about it. The metal backing plate helps a lot, but I've seen a couple of safeties that cracked when they were hit hard, and I've seen several 500s that had the recess wear enough on the plastic safeties with the metal backing plate that the safety would re-engage after firing.

I have had to replace two, The weapons were a breecher that was used as a club when it ran dry in CQC.
And the other was from a police issue cruiser that was stored on the floor by the drivers seat between the door and fell out one to many times (not mine)

Under even rough use the original will do IMHO

I have replaced my HD and "go gun" to metal just because I had the extra metal ones on hand. But it was achoice I didnt feel like I needed too and I have not bought new ones for my other Mossbergs and won't.

Thanks all for input.

I bought the 590 last week and walked in a local shop yesterday and saw the 590a1 I had been searching for. Pissed me off.

I guess I will just upgrade the safety.

I had my trigger group fall out of a Mossberg 500,
the front droops out and the gun no longer functions.
You can rack the slide all day long and nothing works.
I picked up an alloy trigger group and don't regret it.
The safety's seem to always break. IDK, maybe i'm hard
On guns. Or maybe I actually use them. Mp

Btw, the trigger groups are the same for 500 and 590
