It used to be conventional wisdom to have a 12 gauge at the ready for self defense. Then, slowly, the tactical world fell back in love with the handgun under the guides of manoeuvrability within the home. The thinking was that the handgun, being a smaller package, was better for one to clear their home. Combined with the higher capacity and ease of reloading, the handgun, was per thinking, the easier to use weapon.
This is, of course, before one even brings up the ability to suppress the weapon, which is good for the defender to maintain their hearing.
However, Thunder Ranch posits that this significant manoeuvrability advantage is overstated. While sure, the shotgun is a longer weapon, when presented to a target its really not significantly longer than the handgun at full arm extension in the proper firing position. They back this up with a quick demonstration of a common Mossberg 500, an over-under and a full-size 1911.
There was one point that the instructor made in the video that I think is poignant (paraphrased): “Would you rather fire one shot from a handgun at a guy running at you with a knife or a shotshell?”
I, for one, will take the shotshell.
Unfortunately, I have wee ones floating around so the need to keep the weapon locked up while easily accessible trumps my desire for 00 buck…
