I agree with @MusashiAharon and @JohnB. My first choice would be a .38 Special revolver and my second choice would be a .20ga shotgun. @58marine had a good idea also…double-barrel coach gun with external hammers (also .20ga).
All three options are easy to operate, safer to handle than a semi-auto, have manageable recoil, and less damaging to eardrums.
I have shot a fair number of .357 magnum handguns, though I am not as good a shot as you, apparently. Still, your quote of my comments leaves off the “or higher capacity” justification for a rifle. But, I do agree with your comment about lever guns - of which I am a big fan (including .357 magnum lever guns, among others).
If it weren’t for the difficulty in finding a 7 or 8-shot revolver in .38 special (versus .357 mag - which is fairly easy to find in 7 or 8 shot capacity), I would agree with .38 special as a choice. I typically just put .38 special or .38 special +P, in my .357 magnum revolvers anyway.
Also, I agree with using 20 gauge instead of 12 gauge, for self defense.
Not sure about having the exposed hammers as that could set you up for trouble if:
you don’t cock the hammers but get surprised by the perp and have to shoot asap
you forget to cock the hammers in advance of needing the gun to shoot, and now it is time to shoot and all you hear is “click”
some courts might look at your action of cocking the hammers right before shooting as meaning you had time to escape or take alternative actions - either of which could mean legal trouble for you (and no, I am not a lawyer)
would the shotgun with external hammers have a safety ? if not, then, you could actually be walking around with the gun ready to fire - so, what about the trigger pull - could it be considered too light? If so, you could be accused of unintentional firing of your gun (with possible disastrous effects) (again, I am not a lawyer, but look into these points if you want to see what the experts say about them)
Regarding the semiauto shotgun - I can see it both ways (better or more dangerous), for the new shooter.
Its called single double action. Pull the trigger
Being raised on 1911s, I always pull the hammer back on the Sig 45. Its just habit.
All over this forum I say, I am a rifleman. Dont like handguns, have no use for them.
Ive shot the Mrs 357 once, to see if it works.
When you been shooting for over 50 years, you kinda get the feel of it.
I consider the 45 a shooter out to 75-100 yards. The 357, point blank to 10 feet. Different tools for different jobs.
Things like a walking stick or folding walkers can be a very effective long-range defensive tool.
, the author demonstrates the starting position from which
the stick can be used as a shield and strike weapon.
I think the safest self-defense tool is the one you carry on you at all times. The “best” weapon for self-defense is the one that is in your hand when you need it.
