Hey guys-quick question... I have a (parkerized) Mossberg 500 "Persuader" and as much as I like wood/walnut...this gun is a constant companion. Just love shooting it. Was discussing it with a buddy who has at least one 590A1, and he mentioned that the model I have likely has a plastic trigger guard. I thought he might have been wrong about that...but nope, it's plastic.

I've upgraded the safety to a metal one (Tactical Ordnance helped-out :) ) and while I have no real issue with polymer parts on guns, I'm contemplating an upgrade to a metal one as the second, and last item of business for this Mossberg.

Had a quick look in the EE and see nothing being offered, so this is a two-part question;

1.do these ever come up for sale used, or, where might one order a new one? (price?)
2.have any of you ever had a polymer one fail/would you bother with the the expense of a metal one?

I believe the trigger group on my 870 Express is polymer too, and upgrading that has never even crossed my mind. Likely won't either. lol I do look at this parkerized Persuader and see a "poor man's 590A1"...so toying with the idea of this little improvement, if it even is one.

Thoughts?
 
I personally think the force required to break the plastic trigger guard would be strong enough to likely bugger up the trigger too. Plastic could very well survive a blow better than aluminum, as cast aluminum will just flat out break. I have both on various scatter guns, I personally have never felt that the plastic was more fragile than the aluminum. To truly know which would be better, would need to scientifically smash both and see which can survive the stronger blow. My money would say plastic could even come out on top, at the least it wouldn't warrant switching out unless at small cost. If you just like metal, I can appreciate that and then you should swap it out. Could be cheaper to buy another gun and swap parts out though.
 
The 590A1 Specification in the TDP is for Marines jumping across the space between sea vessels and go pushing through a lead rain sh*t show below decks smacking the weapon off of bulkheads and skulls. It is a spec to make it "Marine Resistant". Unless you're a crayon eater in Fleet Protection or on a Boarding Team, you should be good with a plastic trigger guard.

-S.
 
The plastic works fine for regular use. If you start using it as a hammer or a bat, the metal would work better.

Brownells ...
 
I did buy a old mossberg 500 with the plastic trigger guard and the tabs that hook into the reciever were so worn down the trigger would not function properly because it wouldn't stay in the receiver. This was probably from incorrectly/forcing the trigger guard into place when installing it. At least something to think about when dealing with those plastic ones.
 
The plastic trigger assembly tabs shearing off was a random issue on older guns with hard use , Mossberg has since redesigned and beefed them up , I know this , from trying to fit a new trigger group to a older gun , [ones with square ejection ports are older guns .] It wouldn't fit .
I also read somewhere, don't recall where, that the U.S. military tested and are using mossberg 500's with the plastic trigger assembly , that might of been just the Army , but you do see them using a lot of plan jane 500's .
 
I thought about doing this too. Like Greenhorse six said, the tabs are way more beefy than the old ones. I can't be certain about this but, I think it is a different polymer than the old ones. Todays polymer used on firearms is far better than the brittle "plastic" of pre 1990's.
Besides I tried to get hold of an aluminium trigger group housing and I was told you have to send the gun in with a work order to get it changed (Wolverine supplies).

Now as for the safety switch, I'd definitely switch that out with an aluminium one. S&J hardware can fix you up with one or there are plenty of them out there.
 
If you decide to proceed with the aluminum trigger group let me know I can get you one. I'm just outside hamilton ON.

Also from experience in parting out dozens of 500/590/590a1 yearly I've tried mixing parts across the board. I know older 400/500ab parts are different designs ( same overall figure but slightly different designs) on almost every part so don't try and use them unless you want a headache.... However I recently parted a 2020 590a1 retrograde. I tried putting that trigger group in a 2009 20" persuader gun and the trigger group would not go in. I compared the plastic from the 2009 gun to the aluminum 2020 590a1 and the front tabs that slide in in to the receiever first that the trigger group pivots off of for install and removal were different, the overal height and location of said tabs were millimeters off but enough that it would work. Just thought I'd mention that if you have a older gun try and find a trigger group out of the same time frame to ensure it'll fit. Newer guns seem to have ever slightly different castings.
 
Never had problems with either the Plastic or Metal (have both). If you are in a hard use situation, buy the metal. If not, don't bother as it'll last the life of the shotgun.

PM'd!
 
I also confirm i seen on a forum a guy from us tested both trigger to impact and new trigger plastic are holding better if you are using them as a hammer. Also tried to fit a plastic trigger to a old mossberg and the tabs were too big, but could fit after a small filing.

If you ask me which one i prefere.. i would without hesitation take a aluminum one! Just because it looks way more better premium than plastic, prefere the look over strenght because i do not intent using that for hitting skulls lol
