It took me a long time to find a shotgun that I felt met all my requirements for a dedicated HD/PD shotgun. Please see my lengthy list of requirements below:
1) 3 Points of contact.
2) Lightweight and easy to maneuver but not too lightweight, and not too easy to maneuver.
3) Buckshot with reasonable recoil because I wanted it to be lightweight. Subsonic buckshot would be even better.
4) Easy manual of arms, so that anyone in the house could use it in an emergency especially when teamed up with requirements 1-3.
5) At least 5 round capacity, with a reasonable ability to be reloaded.
6) Rail for mounting a light/laser.
7) Fiber optic slug gun style sights, cause I hate brass beads, and the light will make that fiber optic pop.
8) Be a double action revolver with a long smooth bore barrel.
9) Cheap so that I dont really care if the police confiscate it after a HD/PD situation.
10) Wood furniture, none of that scary black polymer, needs to look like grandpa's grandma's old hunting gun from before the 20th century.
As you can see my requirements were ridiculous. Surely no firearm on the market could meet that long list of contradictory requirements. Well that is where you would be wrong dear reader. Let me introduce you to the LKCI Eternal Rev410. I keep it loaded with
THE gold standard of .410 defensive ammunition Federal Premium Personal Defense 3" 000 Buckshot 5 Pellet, with a speed strip for reloads. I have an offset no brand name laser light combo from amazon mounted on it that makes the fiberoptic front sight pop, and the enemy soil themselves with terror when they notice the red dot. The only thing she needs is a saddle on the buttstock to hold that speed strip for me.
If you are curious as to whether or not that buckshot will be subsonic from such a long barrel (24" cause I cant find a local gunsmith brave enough to tackle her gorgeous Turkish craftsmanship and chop a bit under 6" off the barrel for me) well let me direct you to this site.
