View Full Version : Mossberg 500 - Frustration

February 20, 2011, 01:23 PM
Hey Everyone,

A few months ago, I purchased a brand new Mossberg 500. Because of stuff going on in the "real world," I didn't get to use it as much as I would like (I shot a few times 25-50 shells total). A few weeks ago, I went out an shot my first round of sporting clays (100 clays total). After shooting for the first time, I tried to reengage the safety and it wouldn't budge from the "off" position. I finished up my round (unloaded and chamber open of course when moving from station to station) and when I got home I tried again and the safety worked fine. I figured that is was some sort of fluke.

Last weekend, I went out and used my trap launched to launch some trap. Again, after this first shot, I tried to reengage the safety and it wouldn't budge. I continued to shoot and shot 110-115 more shells. I then launched a trap, mounted the gun and pulled the trigger. Nothing. I looked at the safety and it was positioned midway between safe and fire, but appeared to be engaged. The safety button itself felt loose.

I am more than a little bit frustrated with Mossberg right now. I recognize that the Mossberg 500 is a utility shotgun, but, in my opinion, it shouldn't break within the first several times I try to use it.

I emailed Mossberg about having it serviced under the warranty and they said to send it back to them. I am frustrated that I have to pay for it to be shipped back to them as well. Anyone have any recommendations on how to ship a gun like this?

Spray some CLP or equavalent and let it soak in overnight in the horizontal position. Maybe just gunked-up with factory lub.
If you bought it at Wal-Mart, they will return it to the factory at no cost to you during the first year of ownership.

I suspect sending the gun to Mossberg will exceed the cost of the repair. Rest assured, you are not the first person to express dissatisfaction with the M-500 safety. Many folks chose to replace the factory unit, have a look at http://www.brownells.com/1/3/mossberg-500-safety-replacement.

hmm? :confused:

my mossberg has been great. i've put over 500 rounds without any hiccups.

That's the one and persistent flaw in a 500.
And it's been one for a very long time.
Just buy yourself a steel replacement and carry on.
It's an easy fix.

Here is a link to a pictorial that I did on the disassembly and reassembly of a 500. If you disassemble it you can then clean and/or replace the safety.

To save some shipping cost just send the receiver.

ask mossberg to send you a prepaid shipping label.
they will do it if you push them for it.
mention the FACTORY defective safety mechanism.
worked for me.:)

The cause is usually an overtorquing of the bolt that holds the stock on. Or an aftermarket bolt that is too long. If you look inside that silver L shaped thing gets bent by the bolt.

i don't have a Mossberg but have heard of a couple of complaints with the safety. One has to do with the bolts mentioned by Kmar40. Another involves staking a detent ball. See http://www.thehighroad.org/archive/index.php/t-146938.html and the post by mnrivrat. I don't know if switching out he plastic safety slide without staking the detent ball will do the trick but I think it would if the problem you are encountering is due to your detent ball becoming wedged in the plastic safety button.
