TheMan 45 Posted June 23, 2015 I was at the range today shooting 12ga slugs when i noticed my switch would not go to safe. Its stuck on fire. Anyone else have these issues? Although its locked through chamber im concerned. Thanks Quote Share this post Link to post Share on other sites
RecessedFilter 222 Posted June 23, 2015 There are 4 or 5 parts in the safety mechanism. It sounds like it may be dirty or there is grit in there but something could have also broke. There is the screw that holds the safety button down, the safety plate under that, that little ball, then there's a little spring. Maybe the spring could have broken?

RecessedFilter 222 Posted June 23, 2015 I'd take it apart, then look at a Mossberg 500 parts schematic and go from there. Quote Share this post Link to post Share on other sites
Lalo 13 Posted June 23, 2015 I'd take it apart, then look at a Mossberg 500 parts schematic and go from there. Do this, it's pretty easy to take it apart. Now might be a good time to upgrade to a big button safety. Quote Share this post Link to post Share on other sites
Old Glock guy 1,125 Posted June 23, 2015 Do this, it's pretty easy to take it apart. Now might be a good time to upgrade to a big button safety. Good advice on the larger, enhanced safety. They are available at Brownells, and are relatively inexpensive (I believe somewhere around $10). I like the one I have on one of my Mossbergs, and have purchased them for my other four, but have not been able to figure out how to remove the special, tamper-resistant retaining screw. Any advice?

Lalo 13 Posted June 23, 2015 Hardware store has a tool for it. Should be >$10 Quote Share this post Link to post Share on other sites
DeerSlayer 241 Posted June 24, 2015 Last time I broke the plastic original safety switch I replaced it with a billet aluminum one off eBay for $5 + shipping. came with the tamper proof screwdriver as well. Quote Share this post Link to post Share on other sites
Old Glock guy 1,125 Posted June 24, 2015 Thanks Lalo! I'll have to track one of those down. Tried a couple of local hardware stores, but they didn't have them. I'll try a couple more before resorting to Amazon. Quote Share this post Link to post Share on other sites
boo 6 Posted June 25, 2015 I was able to loosen the screw on mine by hitting it just right with a pin punch, then followed by a screwdriver with heavy downward pressure. Quote Share this post Link to post Share on other sites

Old Glock guy 1,125 Posted June 25, 2015 I was able to loosen the screw on mine by hitting it just right with a pin punch, then followed by a screwdriver with heavy downward pressure. There's a YouTube video that shows it being done that way, but I seem to be challenged in the use of tools, because I had no success with it. Quote Share this post Link to post Share on other sites
