Like I previously stated, I'm not a ballistics experts, but I do know penetration is only part of the equation. You can often get massive penetration, but inadequate wound tracks. I'll still defer to those more knowledgeable who say they are not sufficient until someone can articulate why they are wrong.
I don't see why what Jerry Miculek has to says about it has any merit. He's a sportsman and exhibition shooter, not a self-defense expert. Plus he's an S&W employee.
You seemed completely focused on the ballistics of the Governor as if they are somehow superior to anything else available. Even if they are acceptable, there are still far better platforms available. My issues are more with the gun itself. And ballistics are not everything. A 12 gauge shotgun has far superior ballistics to my home defense combo of a S&W 642/Glock 17, but Force-on-Force training has convinced me that any long gun has extremely limited applications in my specific situation. So, even if the Governor was indeed an extremely powerful handgun shotgun with far better ballistics than anything I own, I still find fault in the gun itself.
There's nothing wrong with .45 ACP, but I don't like pistol caliber revolvers because of the moon-clip issue. There are just too many potential problems IMO whether or not you use them to consider a gun cut for moonclips suitable for defensive purposes. The concept is neat, but the reality falls flat.
.45 Colt is a serious round, but how many suitable personal defense handguns are chambered in it? Plus there are better choices if that's your caliber of choice for some reason, but .357/.38 special and the guns that fire them makes a lot more sense to me.
The fact remains that the Governor is massive for being a snub revolver. With guns this size, you usually get the benefit of a much longer barrel, but you trade that away with the ridiculously large cylinder to gain the ability to fire .410 shot shells which to me isn't an advantage at all.
All home defense scenarios are not going to be cases of a creeping late night intruder who has gained entry into your home coming down your hallway while you lie in wait in your bedroom. Many home invasions occur during daytime hours and are violently dynamic. They can happen when you are watching tv on the couch, eating dinner, step out to get the mail, take out the trash, walk the dog etc. These would all be reactive close-quarter situations and the Governor lacks the ECQ advantages that an enclosed hammer J-frame does. I have no issues slipping my 642 in my pocket and having it available at all times, but can you say the same about the Governor? It's size is so prohibitive that it actually isn't very versatile at all. And consider that you might be seperated from other family members with the intruder(s) between you and your family.
Even if you are willing to carry it at home, it's slow to access and offers relatively poor close-quarter handling and inherent weapon retention. If relegated to a "nightstand gun", I would much rather have a more shootable, much higher capacity weapon. Why limit yourself to simply viable when there are much better options.
