1). Is your SD gun more than 20 seconds from your reach right now?
No... More like within arm's reach.
2) How many dependable rounds of ammo for your SD gun could you gather-up and put into action within the next 5 minutes?
Five minutes? If I choose .45 acp, which I would, easily over 1000 rounds. If I were to choose 9mm, about the same.
3) In your SD's present condition, will it reliably fire 200 rds or more without lubricaton concern? If not, how many rounds would it fire?
Yes.
Bonus Question: Would your instructor or shooting partner share the same level of confindence that you have in your answers?
Yes.
