My dad has a cruiser and the safety is messed up. I don't know exactly what iis wrong. But I know he has a piece of duct tape holding the saftey into place... and when you shoot sometimes the saftey will engauge for no reason and you'll have to move the safety to get it to work. Anyway, I want to get him a saftey for for Christmas. Which one do I get. I was looking on Brownells and found these three:

http://www.brownells.com/aspx/NS/st...&title=SAFETY+BUTTON,+MILITARY+SPECIAL,+METAL

I don't know which one to get. I've read on this site that you can replace them with a metal one that doesn't break. Is it one of these that I linked? if so, which one? If not, can you link me to the proper one?

thanks

Thanks.
 
Your third link is the metal replacement (the first is also metal.) Given that there's duct tape holding it in place, you might want to figure out what all is wrong with it, since you might need additional parts to fix it.
 
The Mossberg safety is excessively exposed, and thus exposed to breakage if scraped hard against an object such as a metal tool box (like in a car trunk.)

Browning has a similiar safety, but solved the problem by recessing the safety in a "trench", so no idle hard object can scrape the safety and break it.

I honestly think the best replacement part is a Remington 870.
 
I think what happened is it broke off. Now it's loose. I'll ask him.

Is the first one just as good as the 3rd one?

I'd also like to know because I just found a Mossy that I might buy. And I'd do the safety modification right off the bat to ensure it always works properly.
 
The first and the second safeties are just fine for the application.

I hope you're trying to be funny.
 
Your first link is an oversized button, but it's aluminum and should be fine, if you want one that size. The third link is the same as the original button, only made of metal. I believe your second link is for the screw that holds it on.

I've never broken a plastic button in ~20 years of shooting 500s, but the metal one should be more than plenty durable. I have one, and if I ever break a button, I guess I'll put it on. :)
 
Either aluminum safety fixes it. The safety problems are no worse on a getting people killed scale than the feeding problems non flextab 870s have, or a lawyer lock working its way to the on position.
 
So other than the plastic 'switch' the safety is is just as good as any other safety?

I don't want anything that's unsafe. But the fit and feel of the Mossy suits me best.

Andrew... noticed your in Bakersfield. I live in Ridgecrest... 2nd biggest city in Kern county. :p
 
You may have a second problem that is somewhat common to the Mossy safety.
I would plan on replacing the factory plastic safety buttom with a metal one because the plastic ones are a notorious weak spot.

The second problem incountered most often is the detent ball excaping. This ball is staked into the reciever and is spring loaded. It holds the safety in position , and if gone, it will allow the safety to drift on and off . If pushed past its staking it will interfere with operation.
 
sounds like he has the second problem. Hence the duct tape.

how do you fix that?
how do you prevent that?
 
So weird to meet people from Ridgecrest (or the general area). I have a mustang and moderate a forum and found out that another member lived just around the corner from me. Ahh, small world.

Cool, glad to hear it just as safe. I just want to take the precautions to make sure the safety stays the way it should.

_______________ "

1.) To repair you must re-stake the ball in place . Since it is under spring tension it is rather tricky. Secure the reciver in a padded vice - What I did is hollow ground the end of a punch that was one size larger than the detent hole. Place the spring into the hole with the ball resting on the top - push the ball down using the end of the punch and give a couple light taps on the punch to re-stake.
The hollow ground punch (concave end) will help keep the ball from shooting off into space, and will act well as a staking tool to move a small amount of metal around the top of the hole inward to keep the ball from coming back out.

NOTE: Care must be taken not to overdo the staking - light taps with a small hammer. If overdone the ball will be staked too deeply and won't bear on the safety botton.

2.) Most of the time the ball is lost as a result of the safety button screw being loose , or when a safety buttom cracks. This allows the ball to ride to high and bear pressure on its staking. After while the staking wears and the ball can ride out of the reciever . Prevention is putting in a metal safety button and/or keeping the screw snug.
