Is it "specifically" designed for a pistol or will it fit on a Picatinny rail on a Mossberg 500?

It should fit, perhaps snug, but it should fit. I put one on my Weatherby PA-459 Reaper, and it was tight, but didn't scratch or damage the polymer forearm. You should be good to go.

Not quite sure. However, if you do own a mossberg 500, it is a perfect fit for it and you do have a little more room to spare.

Hi Mike, this mount is 1 3/4" long and fits perfectly on my Maverick 88. Should fit on your Mossberg 500 just as good. Good luck

Probably not...it is meant to be mounted on either a picatinny rail or with a clamp on to a shotgun barrel.

It should work on any pistol with a rail, you have to have a rail to mount it on.

Yes in fact it works on both the mossberg 500 and the 88 but it is strictly for the 18.5 and 20 inch barrels .

I have it mounted on a rifle, A converted Saiga AK 7.62 with a picatinny rail. It would depend on the mount you have set up on the pistols.

Yes. It fits on a standard 1913 picatinny rail. I just measured one and it measures at 20mm.

not familiar enough with the Circuit Judge to say that it will or will not fit... fits a Mossberg 500 well enough... nice sight, but the ghost ring is held with a very small set screw and it didn't stay on very long (about half way through a tactical shotgun match, which is more abuse than most folks will subject it to)...

Okay here is what I could find out. I went on bing and looked at several 500a pictures. It looks to me like the 500a has all the pins and SCREWS required for this mount. If you open up your action (bolt to the rear) and look in on the far side (left side looking down barrel @ front sigth) you will see a small screw head. This screw holds the ejector ridge on. This is the only screw you need to remove. It is a good idle to put it in a safe place in case you change your mind later or want to put the mount on another weapon. Be careful with the screw that you replace the trigger houseing retaining pin with just snug it down not too much force. They say this mount is only for 12 gauges but I had no trouble getting it to fit my 20 gauge went right on out of the box with no problems. Maybe the folks at Weaver don't know that Mossberg makes a 20 guage. However you should have no problems. From what I could see from pictures. Hank

No. I re read the description and says it will fit any picatinny rail, and that is with the supplied mount. But with the right mount yes it will.

I purchased the Blackhawk Butstock Shell holder for my Mossberg 500. That model should fit most "standard" gun stocks.

It only fits on a Picatinny rail. If you gun does not have one then you will need to see if Ruger makes a rail adapter for you firearm.

It will mount to any standard size picatinny/weaver rail. Consider that with a pistol, it will no longer fit in a standard size holster with this fitted.

Flip your gun over and look at the bottom of the receiver in front of the loading/ejection port. If it says mossberg 500 or Mossberg 590 it will fit.

Does it have a rail system? This light will only fit onto a picatinny rail setup. I do not know if one is or can be attached to the mossberg 500. note: Just checked and a rail system can be setup for the 500. So again, if it has a rail, this should fit it. The light is very nice and very bright. Hope this helps.

I think the picatinny rail and ghost ring shroud might make it too wide. Especially If you have optics on the rail. It seems to work best with a basic 500 or Rem 870.
