The firing pin has to drop before it will pump. The button underneath is to safely unload it. If you have it unloaded or use whats called snap caps you pull the trigger and then the action will unlock. Here is a manual and that is covered on page 2.

Mossberg.com will get you set up. But you won't really need one. Just hit youtube and watch some videos on the Mossberg 500. Yours is a .410 caliber model 500. Nice gun. Congrats!

Weak main spring. It's the back-most pin in the trigger group. The spring isn't moving fast enough to get the hammer past the half **** notch on the hammer. It's catching the sear. In a pinch, you can just jerk the trigger extra stout, no hesitation. If you have a decent stone, you can stone off the half **** notch on the hammer. The half **** is when you pull the trigger group out of the gun and hold the hammer lightly as you pull the trigger. The spot where the hammer locks straight up and down is the half **** notch. Current hammers don't have the half ****....it's simply not necessary. It was a redundant safety feature if the gun ever fell hard when cocked and chambered. It causes more probs than it fixes, though. You can replace your hammer with a new part....all of them fit including the Mossberg 500 lines....or you can stone the notch yourself....or you can replace the main spring. All will fix your prob.

Great gun, btw! I have one and love it!

The 535 is simply a slightly stretched model 500. It can chamber and fire 3.5" shells where the 500 will only handle up to 3" shells. The guns are identical in function and pretty much identical in parts except the stretched bits.
