Home Defense Shotgun Setup

As antisemitism continues to rise I want to remind my fellow Jewish Americans that if you aren't armed for self defense, you need to be. See my free book, "Guns for Jews," which is a free book I wrote to help Jewish Americans arm themselves. It's a PDF hosted on my Google Drive.

Ideally, your first gun should be a handgun to along with a concealed carry permit. However, many jurisdictions where Jewish Americans live make it difficult and time consuming to get a handgun and a carry permit. Something you can probably get with less paperwork and delay is a shotgun for home defense.




I've had this Mossberg 500 Mariner 12 gauge shotgun for close to 20 years. It's pretty much a dedicated home defense gun, although I did use it in one or two action matches over 10 years ago. Recently, I've done a few mods to make it more useful for me.

When choosing these modifications, I kept Greg Ellifritz's comments in these posts in mind:

So, after a couple different configurations over the years, I think I've settled on my final set up:

  1. Magpul SGA stock, set to my length of pull using spacers. Five extra rounds are kept in a Hill People Gear stock cuff. I also added a QD sling swivel stud to the stock.
  2. A Hi Viz clamp on fiber optic front sight, which much more visible and taller than the factory bead. This corrected the high point of impact with the factory bead.
  3. Defender Tactical Mini-Pro Lifer and Cartridge Arrestor System, so I can shoot the 1.75" mini shells.
  4. CVLIFE 1.25" quickly adjustable rifle sling.
  5. CDM Gear ROC-12 accessory rail.
  6. Inforce WML 400 lumen weapon light mounted so I can activate it using my right thumb (I'm left handed).



I've been wanting to try out 1.75" mini shells due to their reduced recoil and because you can load more in the tube magazine. Mossberg shotguns are easily modified to run with the mini shells with adapters from either Op Sol or Defender Tactical. The Mossberg 590S comes from the factory already setup to handle mini-shells.

Even if I keep the gun loaded with Federal 2.75" 00 Flitecontrol for now, the mini shell adaptor gives me the ability to use reduced recoil loads when I'm older.

Since I no longer have any small children in the house, the gun is kept in a closet "cruiser ready," i.e., full magazine, empty chamber, bolt locked forward.

Set up this way, the Mossberg will handle any home defense situation I can reasonably think of in my suburban location.
