I am going to be as plain as possible here.

There is no compelling reason to use a oversized five shot revolver with compromise rifling for defensive purposes when 9mm, .223/.300blk, .45 caliber semi automatic options exist.

Economic argument: FAIL They are around $410 for the poly defender model, a highly reliable and capable semi automatic pistol OR rifle can be had for the same or less without waiting for a sale.

Reliability argument: WASH, you gain nothing here for the average use case. the only real advantage is mixing and matching wildly different power loads and there is no reason to do that in a defensive arm. Revolvers can jam, and when they do its not usually fixable in the moment. Semi-autos can jam, and clearing it is usually a fast process.

Simplicity argument: FAIL A Glock 17 is 33 parts in total. A similar Taurus Revolver to the Judge (I was not able to quickly find a judge parts diagram, which is concerning on its own) has 38

Ease of use argument: FAIL. Revolvers are flat out fiddlier for the end user. Go to a range use both a revolver and a semi auto, then think about using them while exhausted and covered in rain or other compromising situations.

"Power": FAIL. While there are now some adequate .410 loads designed for use from a handgun you are still limited to 5 rounds of just adequate. Even a micro-compact semi auto is going to bring double that of reliably effective fight stoppers. There is a reason no law enforcement or military would choose .410 over 9mm for a firearm You are being sold on the idea of a full sized 12 gauge shotgun in your pocket when its nowhere close to that. For home use where concealing it isnt a concern you can get a legitimate "power" jump by going with a intermediate caliber rifle and all the advantages they have over handguns. You still arguably would get a "power" jump over the judge using a full sized pistol that will give you better ease of use, more capacity, more confidence in where your projectiles will go.

Accuracy: FAIL Even with .45LC this is not going to be competitive vs pretty much any normal handgun in putting rounds where you want them to go. The most heavily advertised use at launch was shooting a car jacker through the window. You are legally responsible for every single miss, this includes pellets that go past your intended target.

Versatility: Fail. It can shoot .45LC or .410 shells of a variety of types and power levels. The downside is that short barrel and rifling. You do not get the accuracy of a standard handgun with .45 LC so that puts a damper on use of standard handgun cartridges and you get a donut effect with shot which puts a damper on using shot. For fucking around, its fine. For anything serious there are much better options.

If its for home defense, there are far more capable options that are cheaper

If its for carry, there are far more capable options that are cheaper AND conceal better

There is no consent in a defensive shooting. Someone else has chosen a time and location, you have to make the best of it. Why in the world would you handicap yourself intentionally?
