Here’s my dilemma: I have a carbine, but I don’t really know anything about using it (outside of basic load, unload, and which end the bullet comes out). I’m much more oriented to a handgun, which is what I’ve had all of my training and practice with.
A carbine’s potency as a home defense weapon can’t be ignored, however. Mine has an always-on red dot, and is presently loaded with a Magpul 40-round magazine. It’s just that my familiarity with it is so lacking that I’m hesitant to consider employing it in a home defense scenario, electing to use the pistol with which I'm much more familiar.
I think it’s a bit of a problem of relativity. I can clear any kind of stoppage with my Glock if I were blindfolded. I can’t clear a stoppage in my carbine at all. But decent guns tend to work most of the time, so I don’t even know if that’s a relevant criterion.
So my question is: at what point are you sufficiently competent to start using any particular tool for your protection? And if you’re more proficient with a less potent tool, do you sacrifice proficiency for potency?
