Mossberg 500 Oddity

I noticed last night that you can depress the slide lock button on a Mossberg 500 and still pull the trigger, with the action apparently unlocked. In fact, I have TWO that will do this, so I don't think it's a defect of one gun.

You can't pull the trigger if the slide lock button is pressed on an 870. Or, at least, not on mine.

Admittedly, you have to work at it to do this, but wouldn't it be unsafe if the button was pressed while it was being fired?

Also, for those of you who have pistol grip or assault-style stocks on a Mossy 500: How do you get to the slide lock button with that type stock? Do you have to roll the whole gun upside down to use it?

I just tried this on a 590A1 and can confirm...trigger can be pulled with the slide release depressed.

I can also confirm that it's not possible on my 870's; the slide release seems to disengage the trigger. Also, it's harder to perform the manipulation on an 870, with the slide release way out in front of the trigger guard.

OK, who's going to go out and perform the test we're all waiting for? I would, but I have to alphabetize my sock drawer.

I tried it on my 12G Mossie 500 and, eeeeyup, depress the slidelock and you can pull the trigger.

Must be a feature, not a bug.....

Clearly it's not a problem or we would have heard of blown up 500's by now. You have to pull back on the forend to unlock the bolt while depressing the slide lock. If you have another hand leftover to pull the trigger, then I guess you and your unicorn are quite unique.

Near as I can tell, the action is unlocked as soon as the button is depressed.

I found that if you really worked at, you can press the button and pull the trigger right-handed from the hip. Just about impossible (for me anyway) to do it from a normal shoulder firing position, and I wasn't able to do it left-handed at all, even though at first glance that seems like it would be easier.
